WebApr 23, 2024 · A RC servo has a single turn pot on it for feedback so you would need to take it apart and modify for direct DC to the motor instead of the internal single turn PWM control. The motor controller in your link appears to be a PWM version, there are many on ebay for around $4.00.

It linearly increases with speed, matching the control voltage at full speed. EMF from the inductance of the motor - This can potentially be very high, and can destroy components.

WebDec 20, 2006 · Depending upon the current drawn by the motor. You can use a LM 317 with a pot meter on the adjustment leg so the potmeter only carries a few mA's and the IC controls the current ( this is ok, up to 1 - 1.5 Amps). Or, use a power transistor and control the base bias by means of a pot meter. WebMar 28, 2024 · How to reduce speed of DC motor using resistor.

WebMay 18, 2013 · 804. May 16, 2013. #9. That's a really easy way to make a slow start for a motor. (I hope the attachment shows up) Bascially you use a transistor to drive the motor . The base is biased by a potential divider made by a resistor and a capacitor. When you power it up , the base will be at 0volts because the capacitor is empty , it starts charging ...
