  • hello friend, I ordered on pcbway and assembled it after I tried the speed control (potentiometer) it didn't work, the motor ran very fast as if there was no control, and when I turned left the motor potentiometer stopped...please advise

    Hi. Usually the regulator behaves so when there is no signal from the tacho-sensor or the TDA1085 microcircuit may be faulty (entrance from the tacho-sensor). You also need to check the tacho-sensor.

    yes thanks, I checked and the problem was in the TDA1085C IC, I replaced a new one and I ran it.. it was running normally for 40 minutes and the TDA1085C IC was broken again (the green and yellow power LEDs didn't light up) I think it's a problem in the IC again.. is there no IC protection or is my IC fake? what do you think???..I will send a photo of the module that I worked on to your email maybe you can give advice ...

  • Здравствуйте, я сделал эту встречу, но она не работает должным образом. Симистор подает на двигатель только 130 В, даже когда он находится под нагрузкой. В чем может быть проблема?
