The motor will not be loaded at the maximum power rate but still isn't 4A too less? Treadmills Circuit Breaker. dear sir i also have 2 HP 180vdc treadmill motor. Do half-wave and full-wave rectification give one and the same effective value of the rectified voltage?! It's not absolutely the same as yours because of the single way rotation needed. ….1N4744 are zener diodes and will never work here, you'll have to use rectifier diodes such as 6A4 etc. Sorry Linus, that may not be possible because I have not seen the board practically so have no idea regarding the various stages. The reed switch for determining RPM appears to be functioning correctly, so I think the issue lies with the motor … Thanks Mah, you are right with your assumptions, however converting 220V AC to DC will result in 310 V, which can damage the motor. 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. Please help me. ... wiring diagram for treadmill motor control, trojan treamill motor dive board wiring diagram, treadmill schematic diagram, wiring diagram a tread mill motor and controller diagram, treadmill/triump rti 8 … Please send me the Simulated File i.e Multisim or Proteous File if possible. hi Ialso have a treadmill motor@130vdc @15amps Iwill be120vac with a brige for and feeding the ic with 0-18 vdc after wiring and putting in all the parts needed, my question is where dose the 130vdc come from to hook up the motor??? It is replaced with a 100uF in the second diagram. 130 (+) to the point indicated as "motor voltage"the pulses are applied to the respective transistor bases. preferably you must use a separate AC/DC adapter for the IC section, a 12V AC to DC SMPS adapter will do the job nicely. Ok thanks. 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. Article from the continuous 330V is definitely because of the filter capacitor which is providing a back discharge and not allowing the peak voltage to drop. Thanks for the example but . use 100k for R1 so that the maximum voltage is restricted to below 200V. VFD Start Stop Wiring Diagram: I am here with giving you a VFD start stop wiring diagram for running a VFD through panel board push button and keypad of the VFD (It is called HMI).. Vfd is a short form of variable frequency drive or variable voltage variable frequency drive.The VFDs are working based on changing the input frequency and input voltage of the motor, we can change the speed of the motor. Last Updated on April 25, 2020 by Swagatam 269 Comments. 1) Resistors are 0.25w 5% ! . This step should only be undertaken if you have a lot of knowledge about motors and can easily read an electronics schematic. Hi Mr. Ivan, The first circuit has been tested by me not once but many number of times for different applications. Also how do you suggest I isolate the dpdt switch? My English is not very good and I am using Google Translate, I hope you can interpret me. I need few answers:1. Your email address will not be published. Sole F80 Drive Motor (2013 - 2016) Diagram Part # 34. Your timely help would be highly appreciated, Thanks & Regards Linus Fernandez. This level is directly translated through optimized PWMs at pin#3 of the same IC as explained above. From pin 5 capacitor and resistor in sequence to the gound? when you are not able to troubleshoot a circuit then it's complicated for you. Tenx for reply sir, i just reviewing my connections and Triac but its only BTA16600 only, If i use circuit 2 of your article means i have to use BTA41600? yes 13/14V will cause no harm to the circuit although a fixed 12V is the recommended value….initially you can go ahead with your available set up, and see how it responds. 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. Dec 4, 2020 - How to use IR2110 MOSFET/IGBT driver as high side and low side driver? I have a problem on the kind of project, i would really appreciate any assistance. Price: $14.99 … But before I soldered the components I did a test on a breadboard. That’s equal to around 8 amp current, and the MOSFET is rated to handle 20 amp, so its fine. 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? The idea was requested by Mr. Samuel. Any IC 555 will work. Thanks, Nick. Also let me know if this motor can be run both sides. Hi Jayanth, Rectified 220 V will become 310 V DC which may be too high for the motor. Thanks Ivan, The diameter of the core could be such that it accommodates the 200 turns comfortably, it could be done over an iron bolt or screw…but the diameter of the wire should be more than the indicated 0.6 mm since the motor is rated to carry high currents…a 1.5 mm could be tried initially. Hi Kakooza, if it's a DC motor then you can definitely use the first design which is explained in the above article. I mean like mosfets. thanks again for early replies. … The LED brightness must vary from 0 to max in response to the pot variations. also the design calls for ICMM74C14 can ic4049 be used intead? So this part works. The important thing is that whether or not the dimmer concept works and is able to regulate the motor? Hello Mah, Dimmer circuit is designed to work only for AC loads not for DC loads, because it won’t regulate low DC precisely and a slight wrong adjustment will burn the DC load. I’m Horacio from Argentina. 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. Community Q&A Search. In this post we discuss a simple, accurate, high torque treadmill motor speed controller circuit which may be effectively installed in similar units for acquiring PWM controlled variable speed feature. Let's discuss this question. can i use MOSFET or any other for instead above sir? Glad you liked my site! must feed 180v treadmill motor. Hi Rookie, to which diagram are you referring to?? Permanent Magnet motor. Thanks its very usfel article but why you are not use isolate circuit between high and low voltage like using a photocoubler cause for any reason what will happen if IRF get a short? I am new and lost with all your excellent info.Robert. Power & Electrical Supplies .. 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,, connect a 100 watt bulb in place of the "AC motor" in the above link. No it won’t, the design does not include a torque compensation feature. Thanks again for all your help. 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? Or should I be looking at a different approach to driving that big D.C. Hello Mah, All resistors are 1/4 watt 5% All capacitor rating can be equal to 2 x supply voltage or above. 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. Do you think I’m making a mistake? Should I use a lower power bridge rectifier? 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. The resultant PWMs from the selected NOT gates finally reach the transistorized bridge network that holds the motor between them for implementing all the specified features discussed above. It worked properly untill i turn the pot on 40%. 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. the dimmer chopper circuit above can be used as is it, or some components should be changed. I replaced magnetic sensor still same issue. is it getting hot?….you can first test the circuit with a 200 watt bulb and make sure the bulb dims across the entire pot rotation uniformly…. Motor controller. the BC547 should be actually BC557, please note this. All above told the truth. And what's so hard in the first circuit so I must be an expert in order to run it? For 1500 watts you may have to use a 600 V 16 amp triac. P1 will need to be connected with an appropriately dimensioned series resistor so that the max voltage to the motor is restricted at 220V, because the rectified voltage could be well above 300V. Thanks, mr. Majumdar, one more question, what diameter should the iron core of L1 have? if the blowing-up of the triac was the issue, in that case you try using a bigger and a higher rated triac, and also employ a fuse in series, that would solve the issue. The output starts not from the zero but from few dozens of volts. IC1 stage may be ignored and removed….D2 could be replaced with a 200 V zener diode. At all I intend to use this circuit: Will the motor maintain its torque at any rpm. Now I found another circuit in one of our old elctronic magazines (I'm from Bulgaria). Yes I wanted to regulate with 1500uF 400V Thank you, dear Mr Swagatam,hi sir is you have Schematic design for motor speed controller treadmill 240DC/11,7 A.thanks before I have a 2000W AC dimmer, a 50A 1000V bridge rectifier and a 400V 4.7uF capacitor across the DC output. dear sir, NPN transistors are there but PNP 400v 15A is not found. Hi, mr.Majumdar, I did the first circuit. Hi, Mr. Majumdar, I did exactly as you told me – a half-wave rectifier with 6A4 diode and a 10uF/400V capacitor, but the voltage between the poles of the capacitor is 325V DC! lastly do the uf ratings of the capcitors change with the higher vaoltage needed in my circuit? Remove the MOSFET, connect an LED from pin3 to ground nine via a 1k resistor. As long as I can see it will provide directly 180V from the 230V rectified AC grid voltage in the power line. 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. Rather I was meaning that all the circuit can be set to power the motor to 180V only no matter what the grid voltage is – with other words we have 220V, but the power transistor passes only 180 of them at maximum turn of the potentiometer. Any possibility contact you in skype or phone? I have a treadmill which controller chip has failed and now i would like to build independent control of the motor. Excuse me for the late reply. Explore. 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. 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 … Can I use it again? 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. Thank you for you time and your response would be greatly appreciated. That is already done. just make sure that the drain of the mosfet is isolated from the R1—R5 positive line and gets separately connected with the 300 DC rectified source. My kind request to you is not to proceed with this project, you seem to be extremely new to electronics, and this project is not for the newcomers with no prior experience. , they are having similar voltage and current max. Treadmill Transportation Wheel. Required fields are marked *, on Treadmill Dcmd57 Control Board Wiring Diagram, Treadmill dcmd57 control board wiring diagram. Do i also have to find a mosfet (or BJT) with more than 180V rating? it will work purely on a PWM feed and it could be entirely different from the ordinary triac dimmer concept. By moving the 10K potentiometer the intensity of the led increases. You can add a optocoupler if you want, but it is not necessary. ok so just connect the 130dc on the plus where the motor is connected and the – to 0 rail : I don't understand how the motor would get the pluses. If I use a full-wave rectifier and a smoothing capacitor the rectified voltage will be above the motor's and even transistor's allowable. sorry I can't verify the pics because it can be too time consuming…but I can assure you that the circuit in the first diagram is correct and has been tested by me, now it's upto you to discover the faults by checking it stage wise. They also had a cautionary notice that the T.Mill shouldn't be run beyond 2hrs continuously. And finally, if there's a man on the treadmills belt when the problem occurs, he will fall down, with possible injury. After closer examination it looks like BJTs were wrongly configured. It was BTA41/600 already. The 130v will come from your mains AC outlet after rectifying it through a bridge diode network, although it would become 150V after rectification, can still be used for a 130V motor considering the regulation feature available with the circuit. As rightly suggested by one of the dedicated readers of this blog, Mr. Ivan, a 180 V treadmill motor can be simply controlled through mains phase chopping concept, normally incorporated in all commercial dimmer switches for regulating home fan speed. Would 1N4007 would do it? you can try a IRF450 for your motor application or any other similar. starting voltage/ current= 130vdc/16.2A cont.
