Hi,
I recently got a Wolfgang Engineering TB-650 spindle and I am looking for a PWM unit to control the speed a little bit better. I got a 12V 20A power supply setup and the missing part is the PWM unit.
The motor used in the spindle is a "Atomik 50T 540 Fireball Rock Crawler Brushed Motor" (see RC Car Motor - 50T 540 Fireball Rock Crawler Brushed Motor | Atomik RC) Richard (the guy who sells these) told me he would use a 12V, 20A supply along with a PWM unit on ebay. That one doesn't work very well and just overheats. I suspect it's because it is not meant for inductive loads and lacks flyback diodes.
Also, the motor description says "Input Volts: 4.8-9.6V" instead of 12V, so I am a little puzzled by that. Anybody here who could recommend a PWM unit that would work with this?
Thanks,
Felix
