Re: [TCML] Treadmill Motor Question

Question for the list experts. If one were to employ a DC rsg motor with full wave rectification, are filter caps needed? Is the ripple any worse than pulsed AC from an inverter or pulsed DC from a cheap SCR speed controller?

Response: I had trouble with a DC rectifier on my rotary buring out until I placed MOV's across the input and output lines. The DC supply is close to the rotary motor but in an aluminum box which needs to be grounded to RF ground.
