This is my first post here, and by intro I am a complete noob. Have played around with various electrical things, no real electronics experience, and no education in this area. So please be gentle, and especially please use simplest terminology.
In my work I am rebuilding a device that uses a small DC motor at low rpm. It is labeled "Motor DC - Filter RF - HP .002 - RPM 24 - Volts 27 - Amp .5 - For use on 28 volt DC system". I attempted to use a cheap PWM controller that I bought on Amazon: http://www.amazon.com/DROK-Controll...=UTF8&qid=1418916526&sr=8-1&keywords=DROK+pwm. I supplied 12VDC to the controller. Regardless of the pot setting, the motor runs at one speed. Using a variable resistive controller the speed adjustability is excellent. What am I doing wrong here? Thanks for any thoughts.
