I've tried to put the power in the other way but then it blow out the other diode D3. For 3 HP just make sure to replace the triac with a BTA41/600 so that it is able handle the rated current comfortably, Swag the new motor for the drill press is a D.C. The LED brightness must vary from 0 to max in response to the pot variations. I have updated the required diagram above, please check it out. Building an electronic circuit for achieving DC motor speed control may seem quite simple, and you should be able to find many such ordinary circuits dealing with speed regulation. the dimmer chopper circuit above can be used as is it, or some components should be changed. Hi Rob, I tried to search for a 350V/400V 5/7 amp PNP Darlington transistor but strangely I could not find a single appropriate one. Mosfet based DC Motor Speed Controller. All the elements are the same as required, the circuit has been checked maybe 30-40 times, everything is correct but it doesn't work. But i keep worrying about the smps situation so i just wanted to ask about that. Another interesting feature of this circuit is its capability of sustaining and balancing optimal torque even at lower speeds ensuring a continuous working of the motor without stalling it during extreme low speeds. To control the speed of a 120VDC 2.5 HP motor, should I use the second circuit? I thought the thyristor will work like half-wave rectifier together with the phase cut-off process. I found an older treadmill on FB Marketplace for $80 and made it happen using parts from eBay. or should replace it with a m11021 transistor instead? I am also the founder of the website: https://www.homemade-circuits.com/, where I love sharing my innovative circuit ideas and tutorials. Hi Peter, yes + indicates the +12V line of the circuit itself. If you want the H bridge, then Darlington may not be required. Dear sir, please let me know how can I run a 180v DC treadmill motor with 5400 rpm and 1.5 hp by using 220 v normal ac current in India. does the '+' next to the variable resistor indicate 12v Power Supply? 3.

A lot of these circuits are widely used for motor speed controls. . When i disconnect magnetic sensor motor running full speed. This greatly increases the … Thanks very much Michael, no programing is required for the devices all the ICs come preprogrammed, just have to wire them up in the shown manner. Hi any possibility a ready made controller can be purchased. yes 6A4 is the minimum requirement for the bridge diodes, 1N4001 will not do as these will blow of due to the high motor back emf. use 100k for R1 so that the maximum voltage is restricted to below 200V. This motor is a beast Swag, I have never seen such a large treadmill motor!!! thank you. The list of elements is in bulgarian, that's why I'm not posting it here. Does that work? BTA41-600E which rated 40Amp and 600V could work properly? I don't use them in the bridge. For MOSFET also I couldn’t find a p-channel 400 v 10 amp device. Price: $389.99 Sole Incline Adjustment Switch ... Price: $21.99 Transportation Wheel. The NOT gates which act as inverters provide the feature of instant toggling of the motors rotational direction by a mere flick of the SPDT switch. Healthier Living. the source of the mosfet will connect with the circuit negative. I also had a view of the motor and it was written 180Volts on it. alright I appreciate your help. Exactly that was my second question. Hi sir, I have a DC motor which uses electromanets where Armature Voltage is 70VDC and Field voltage is 90 VDC.Just help with a circuit diagram to power & regulate the speed, thanx. Which of your diagram should I use to power this motor and use 10k pot to control from 0 to max and I would like a reverse on motor can DPDT switch will do? The circuit from the link you posted is with MOSFET, there's no problem to drive it directly from the IC, but in the first circuit above power Darlington BJT's are used. As for the second one, I tried alll the things you said – removing the engine and the bridge and using a 100W lamp as AC load. Hi Swag, Your site is awesome. can i use MOSFET instead above sir? Like is 1 actually 1 and not some other pin? Would you provide such circuit, mr. Majumdar? To power the lamp I used a 220 to 110 VAC transformer (here in Argentinda we use 220V line) that I then rectified with a KBPC3506. I will remove the mosfet and the 10K resistor and I will replace it with a 1K resistor and an LED. What type of transistors would I use for T2-T5? im sorry one more, R4 is that 2.2k or 2002 ? The diagram looks OK, except the transistors in the bridge…you'll need to swap T4/T5 and T2/T3 positions. you can either search for a suitable single device or connect many of these in parallel, just make sure all of these are mounted over a single common heatsink. I see 3 circuits in the article of this web page. . You can upgrade it by adding another NPN/PNP to convert it into a Darlington. Once the triac blowed up and the motor raised its RPM's to the space before the fuse interrupted the mains circuit. But before I soldered the components I did a test on a breadboard. Refer to your original order to verify the warranty period purchased. IN4001 is it enough to counter that much current? (repeating my posting as I'm not sure it went through…) Hi Swagatam, thanks for this. yes IC 556 will work as good as two IC555…. Hello, mr.Mjumdar, I haven't been there long time ago. ...

HP 2.5, RPM 4500, Rotation CW, Duty Continuous. secondly would it be possible to use a dpdt switch instead of the transistor h-bridge for directional control of the pwm signal or would that not work? Is there an easy way to tell?Thanks again for your help. But I have a question. I'm new to electronics so please excuse me if these are dumb questions. You can eliminate the stage that's connected after pin3 of IC2…..you can directly connect the mosfet gate to pin3 of IC2, then connect the load between the motor +V and the mosfet drain. especially the 2nd alternative. Hi ivan, It's not possible to control a mosfet drain load with a varying gate voltage, PWM is the easiest and the most ideal way of achieving the intended speed control through a mosfet. Yes, you are right the NOT gates won't be required in the referred diagram. Your work will be highly appreciated because I'm trying to run this treadmill for 4 months. I'll shall be very thankful to you! The other caps I was going to buy 50VDC ceramic disc. In your first diagram is there any reason you do not include a smoothing capacitor across the bridge rectifier. Why?! my requirement is to utilise treadmill dc motor board to sensorless dc motor. E 33 The walking belt is moving at a faster speed than displayed in the speed window A. OK Wes, that's good! Price: $14.99 … the negative from the rectifier will connect with the negative of the circuit. This type of starter cannot be used for a series machine. 1/4 watt metal film resistors would work, right?C3 is listed as 1uf, what voltage and style of capacitor should i get? TREADMILL MOTOR a) Variable speed 0-110 volts DC motor. Then the bulb got bright like it was in wall socket without any circuit. An exercise treadmill having a direct drive AC induction motor controlled by an AC motor driver/controller. If the auto modes work and the manual does not, you probably need to replace the console. If so is the zener at z1 still needed? What should their values be? 3) Which IC’s should be selected for the circuit ; LM555J, LMC555, BCR555, ICM555CD, NE555P, NE555DR, or ICM7555CD? Just i think its best to isolate between circutis cause if IRF have a short it will pass 180 volt to 555 circuit and we will loss all parts. A very cool and easy DC motor speed controller circuit … The circuit should be supplied with a separate 12V DC, whose ground must be made common with the 180V DC ground. For the transistor you can simply use a single high voltage Darligton transistor such as ST901T with pin3 of IC2 for the required implementation. As always thank you for all you do for the electronics community, it is sure nice to have someone always there to help people through a design or troubleshoot a problem as you do on a daily basis for the whole world….thanks Swag. Thank you Horacio, if your motor is a 120 VDC then you can use the second circuit, however you will to replace the indicated MOSFET with a MOSFET rated at 200 V drain/source capacity. Could you sugest me something?Thank you in advance for your answer. I have a problem on the kind of project, i would really appreciate any assistance. Hi Mr. Majumdar, is it possible for me to reach you through mail please? what are the transistors T1 to T4 should i use? Hi Jayanth, Rectified 220 V will become 310 V DC which may be too high for the motor. Ok thanks. Hello Mah, you can apply the second last design without any changes, except the MOSFET which must be rated at VDs = 200V and ID = 10 amp. I want to build a speed controller for a 90 V dc motor, variable speed, 11 amp. Dimmer circuits are voltage regulator and as you know it can support high currents consumer by using high amp triacs or thyrestors. Below the circuit you indicate “The 10K pot can be used for the speed control, while the 220uF determines the soft start feature. I think it will be much more comfortable for the motor starting at 20-30rpm or even less, for example instead of, let's say, 300rpm. Look up parts for your model on our convenient parts list diagrams and get your treadmill fixed quickly. . As long as I can see it will provide directly 180V from the 230V rectified AC grid voltage in the power line. I don't have a heater coil, but I connected up a 100W bulb (40 ohms) in series with the motor to avoid drawing too much current. According to the datasheet of this it has a build in diode so it lets the DC power go straight thru in one direction. Could i use it for this? thanks sir. I'm and forever will be glad for your work. do any changes have to be made to the alternative designs for my situation? This step should only be undertaken if you have a lot of knowledge about motors and can easily read an electronics schematic. Treadmills Circuit Breaker. The capacitors can be rated at 25V or above. The idea with putting a powerful light bulb as a voltage divider is groundless because of the power it dissipates in the small area of the treadmills motor bay. Dear Linus, It seems the sensor system is installed to control the motor over-speed through feedback…so may be the feedback loop has some problems and it could ne latching ON and stopping the motor from rotating. Hi, Could you explain how a constant torque at low speeds is achieved? I have been planning to use Arduino UNO, the problem is finding the relevant H-bridge driver since the PWM from the arduino is about 5V. The other way is to use half-wave rectifier (single diode) and a capacitor behind it in order to get smoothed voltage with the value motor needs. Hi Swagatam, I have been working on the second circuit to control the speed of a 120VDC 2.5HP treadmill motor without reversing. I think it gives feedback to the controller about the current speed of the engine no matter what is the speed set by the user. I'm trying to fix my treadmill using the dimmer + bridge rectifier option you show at the end. The 180V could be achieved through a half wave rectification using a single 6A4 diode and filtered using a 10uF/400V capacitor. hello, I made the second circuit replacing the mosfet for irfp460 to run a 180v treadmill motor, the problem is that the mosfet overheats and the motor shuts down, what would be the problem? No, triacs cannot be added in parallel, because they have different working characteristics compared to transistors. Besides that, the noise from the motor becomes louder when the RPM's go down. but I cant the ic can only take 18vdc ,130 will fry it???? The disadvantage of this type of starter is that it may drop out if field resistance control is used to weaken the field for increased motor speed. Here's a simple PWM based motor speed controller circuit which can be used for controlling a treadmill speed right from zero to maximum. If you are not interested in the reversing feature the circuit definitely becomes much simpler as shown in the following image: ignore the four diodes shown at the top which was drawn for some other similar application need. Hi Mah, I referred you the second last design, meaning the second circuit from bottom. I don't intend to use MOSFETs anymore. Please remove the two BC547 transistors from pin5 of IC2, remove the associated parts like R9, C5, 10k pot. I just want to make a circuit which can control its speed from zero to maximum. . I really don’t know if that is possible and even more I don’t know how to handle the high starting current of the motor. Any suggestions? Sorry i'm still learning electronic circuit. I tried connecting it to the treadmill and it blew the fuse in the dimmer and destroyed it. Hi Jayanath, yes NPN is available but PNP is not available. These transistors should be rated as per the motor specifications, and the voltage across this bridge should also be as per the motor requirements. You can insert the coil afterwards once all the testing is completed. Could I possibly modify this circuit towork with this type of motor, and if so, what component modifications would be necessary? I ran my 220 and 180 vdc motor by using a 4kw dimmer with bridge rectifier feeding the pwm circuit and worked very well. Thank You. By the way the author of the circuit I uploaded says that the C1 capacitor's value is determined experimentally (between 1 and 10 uF) to choose less jerk and max torque (something like compromise between both). thank you, which circuit are you referring too…? This is an amazing site and appreciate the time you dedicate to helping others. Description: Treadmills How To Read Wiring Diagrams Treadmill Circuit Diagram intended for Treadmill Wiring Diagram, image size 800 X 565 px, and to view image details please click the image. in the second circuit, remove the motor, the bridge diodes network..verify the circuit using an AC lamp as shown in the following lamp, if this doesn't work will mean your circuit is faulty somewhere, 1.bp.blogspot.com/-s2Fe-xTv4YA/T4V-Z597HLI/AAAAAAAABFk/mafeMQ6JYm4/s1600/How+to+Control+AC+Motor+or+a+Ceiling+Fan.jpg, connect a 100 watt bulb in place of the "AC motor" in the above link. I hope it will work much better than the previous one. Would 1N4007 would do it? the 220k variable resistor controls the frequency of the soft start PWMs. 2. . i.imgur.com/NHR9ug3.png. It is label rated at input: 120ac 60hz. 3). Fig 2: DC Motor speed control using PWM method Circuit Explanation: Here N1 inverting Schmitt trigger is configured as an astable multivibrator with a constant … If the requirement is above 30 amps mosfets could be preferred…mosfets require stricter parameters while configuring compared to BJTs therefore sometimes become difficult to handle.however in the above design mosfets could be used since the configuration does not demand a high side driver due to the involvement of both n/p mosftes.. For 1500 watts you may have to use a 600 V 16 amp triac. ….1N4744 are zener diodes and will never work here, you'll have to use rectifier diodes such as 6A4 etc. is it ok to connect rectified 220vac through rectifier to the given points of the motor directly? This is the information i got sir. And Im assuming the 100kpot in the open/close door circut will be the knob I turn up and down to speedup/slowdown the motor is that correct. The idea was requested by Mr. Samuel. 130 (+) to the point indicated as "motor voltage"the pulses are applied to the respective transistor bases. here a link of my half work so far. Treadmill Motor Speed Controller Circuit | Homemade Circuit … The above frequency from pin#3 of IC1 is fed to pin#2 of IC2 which is wired as a standard monostable. But what i dont know is the long time effects. 3rd since i plan on full bridge rectification of 110vac mains and am expecting to end up some where around 156v dc after rectification and my motor only needs 110v would i be able to use a voltage divider to create the 15v vcc input? I will let you know how it is going. Almost like your circuit with a BTA41-600E triac. and for the mosfet the application notes points out that the drain should be connected to a positive terminal of the supply and you say the neg – ??? It's been very helpful. Thanks Mauricio, It is possible since the load gets proper DC from the bridge, while the triac circuit works with an AC, again through the bridge connections. OK, no problem….then you can go with the first PWM based concept, let me know if you have problems while making it…. Is this possible and which way is the best? From pin 5 capacitor and resistor in sequence to the gound? Alright, let it be so, let's forget about this . It worked properly untill i turn the pot on 40%. Use any 200V NPN transistor, connect its base with pin#3 of IC2 directly. …please make sure the negative of 110V DC joins with the 12v negative of the circuit…. the word "simple" was mentioned in context to the subject….compared the complexity of the PWM concept this circuit looks easy that's was I meant to say in the article.. there's another way of keeping the voltage under control, as shown here: 4.bp.blogspot.com/-zEbdlZt9sTo/VEoQWzsHz5I/AAAAAAAAIfs/p53qd3foLaA/s1600/voltage%2Bcontrol%2Bfor%2BIRS2453.png. I have all part of the circuit (without reverse) stuff only IRF840PBF Instead of irf540. the diode polarities inside the bridge is incorrect, it should be exactly as given in my diagram. OK, for the PNP you could probably use MJE5852 and 2SAR340P together to form a 400V rated Darlington transistor, the configuration is simple and may e done as follows: connect the emitter of the 2SAR with the base of MJE, connect their collectors together. Thank you so much for your time. The MOSFET must be rated at 250V or more. At all I intend to use this circuit: 2.bp.blogspot.com/-wJnI3vNWGoo/UoxAV_X6LyI/AAAAAAAAFxU/7NZJ4A2bg88/s1600/treadmill+motor+speed+controller+circuit.png. I have explained how 555 geneartes PWMs in the following article elabprately: https://homemade-circuits.com/2012/12/how-to-use-ic-555-for-generating-pwm.html. Page 41: … Can something else be used instead of diac, for example something from the MOCxxxx zero-cross series? If the riac is appropriately ated it will be able to handle the initial surge. We already have a PWM controlled power transistor, all that remains is just the flywheel circuit (a diode, inductor and a capacitor). Dear Swagatam. Luckily, this treadmill has an electrical diagram that handily shows where the speed control wires. IR2110 Mosfet Driver Pinout, Examples, … I apologize for my lack of knowledge. Thanks Mah, you are right with your assumptions, however converting 220V AC to DC will result in 310 V, which can damage the motor. Do you have any idea what to do? I have a 2000W AC dimmer, a 50A 1000V bridge rectifier and a 400V 4.7uF capacitor across the DC output. The 220k should be adjusted such that transistor in the above link just begins conducting at 190V, an additional 22k preset could be used in series with the 220 k on the input side and used as a fine control preset, in the link above a bridge can be seen, which could be replaced with a single diode from the 220k preset upper lead to the 220V DC. Hello Swag, How can this circuit be used for 180Vdc 5.5 A motor? The output starts not from the zero but from few dozens of volts. Hello Jems, you can remove the entire sensor opto stage to remove the feedback. 1) Resistors are 0.25w 5% ! This level is directly translated through optimized PWMs at pin#3 of the same IC as explained above. there's no voltage on the bulb, but when slightly opened, 207V are suddenly on it and so on until pot gets on max. make sure to use a 100K resistor in series with the pot. The motor controller runs the motor at the speed you select at the console. My pleasure! Or perhaps my several earlier attempts have blown the motor. b) If there is DC voltage on the Red wire (M+) the treadmill motor will turn clockwise. meaning T5 will move to T4 and vice versa, same with T2/T3. It seems that the circuit must be without those NOT gates because of the single way rotation and I'll need only 2 power transistors (in parallel oor in sequence). in the above article 555 IC are shown but if you wish you can use a single 556 instead of the shown two 555. voltage is not indicated because different users may have different voltage requirements as per their motor specs. for operating with 110V DC, you will need to isolate the DPDT connection from the R2 point and connect it with your 110V DC source….and the circuit section will need to be powered from an external 12V DC supply. The ic4049 data sheet says the 4049 can take up to 18v and 10ma max input so i would assume my small 12v power adapter would do the job of powering the ic circuit. I should say that C1,C2,C3 rated voltage are 100V. 2. Thank you very much for the quick answer. does a triac always get hot in such circuits ? Hence the question for the torque. Center leg connected to pin5, the other two legs connected to the +/- supply rails of the 12V DC. i unable to found magnet wires. use the collectors as a single collector, the base of 2SAR as the base, and emitter of MJE as the emitter for the final connection in the circuit. which schematic sir,i am still confuagused? Many thanks Sir. Hey Mah, it is a tested design so it should work. Your email address will not be published. If the circuit is too complicated and the people who will try to build do not have even the slightest idea of how it works and how to be checked for troubleshooting, then what is this all about? . Thanks for the great design! i.imgur.com/VP0JdCE.png. Alternatively you can also try Mosfets in place of BJTs and that would work equally good, according to me. I think is possible to use a controller for an Ac motor made with triac and diac and then to use a rectifier bridge to feed the motor. Glad you liked my site! must feed 180v treadmill motor. I am new and lost with all your excellent info.Robert. However the design is not simple and it's recommended only for the experts in the field who has a thorough knowledge of practical and theoretical electronics. It's not absolutely the same as yours because of the single way rotation needed. Connect a MOSFET with pin3. as mentioned in above comments i should make first circuit and to be eliminated N1 to N6 and S1 joining R6&7 to 2nd ic pin 3. sir. Hi Peter, if a capacitor is used the whole idea of PWM control would get mitigated, because adding filter capacitor would cause a constant peak voltage for the motor and stop the PWM function from controlling the motor speed. 4) D1 is a Zener Diode 2.7v 0.5W? Circuit Diagram. I never imagined that controlling the speed of a DC motor can be so difficult!!! Article from microcontrollerslab.com. The speed cannot be adjusted from zero (at least not in my case) and is unstable. Hello, mr Majumdar, I have something much simplier in view with respect to 180V DC treadmill motor control powered from 220V AC grid. So you will have to attach a large heatsink to the mosfet to control its heating, or add two mosfets in parallel, or use a 300 V 70 amp mosfet or similar which may have a much lower RDson resistance. it will work purely on a PWM feed and it could be entirely different from the ordinary triac dimmer concept. Sorry Michael, I guess I misread it, no problems, you can try the following diagram, this should work perfectly: Please make sure to Add a 1K resistor between pin5 of IC2 and the ground line, I forgot to show it in the diagram. From the thousands of photographs on the net with regards to treadmill wiring diagram, we picks the top selections with best image resolution only for you, and now this photos is among photographs series within our very best photographs gallery about Treadmill Wiring Diagram.Lets hope you may as it. Dimmer Phase Chopper Circuit, 400V 4.7uF and 1500uF 400V capacitor change possible. Add New Question. Kindly correct me about the mentioned circuit about these concerns; 1) I need to convert 220Ac to 180VDc and connect the positive to place indicated as +12VDc in the Circuit ! voltage/ current? It seems the 2 BC547 Darlington is too sensitive to the pot movements. I was intrigued by this circuit design because of “its capability of sustaining and balancing optimal torque even at lower speeds ensuring a continuous working of the motor without stalling it during extreme low speeds.” This is necessary for milling operations. The preset or a pot positioned at pin#5 of IC2 forms a  potential divider network for a selectable fixing of any voltage from zero to maximum supply voltage at pin5 of IC2. Hi, mr.Majumdar, I did the first circuit. I need few answers:1. Sincerely, Michael Sakach. please advise if there is anything else in the auto door control circuit I must change for it to work with my 250w 110v dc motor. Turn Switch off and disconnect. That is already done. Does the C4 (10nF) stay at it's place in that case? Or should I be looking at a different approach to driving that big D.C. Hi Horacio, In the second diagram I forgot to show the 1k resistor across pin5 and ground line of the IC2. Hi Jayanath, BT136 will support upto 200 watts only. How about just changing the gate voltage in order to control the drain current? FIGURE 2: Three-point manual DC motor starter circuit diagram. That why i'm asking the property value and which you used for the project that work and from there I cant experiment. Ok great.. And that reminds me i forgot to mention for the 12v circuit i recall you mentioning an smps power supply however i dont know how to tell if it is a smps powersupply or not… im using a small ac to dc (wall dart) power adapter which belonged to a wireless router enclosure. OK, how about if I use FJL6920 with TIP29C as the NPN darlington? Hello Hasan, do you mean replacing 4.7/400 with 1500/400…?? Can I use it again? the BC547 should be actually BC557, please note this. Thanks Is this possible to use couple of triacs in paralell in order to get higher rated amps? Thanks! Thank you very much Swag for your time, it is much appreciated as always!! Hey Swag, My first attempt to make the circuit as you suggest, was not successful but I am sure I will find a way to fix it ofcourse with your help. It is replaced with a 100uF in the second diagram. . TL494 circuit will also work. Dear Mr. Swagatam thanks for the reply. Thank you very much. Just in case my email is hbarrabasqui@gmail.com Thank you very much!! I want to use the circuit to power a 180V 15A d.c motor but i don't know how to go about modifying the original circuit for this purpose.
