Thanks for your replies and suggestions!
A few comments after experimenting:
ITSMOKED: The motor is rated for continuous duty by the manufacturer;
STARKOPETE: There is no data plate on teh motor that indicates "A,C,D,E, or K). I have asked the manufacturer if that is specified, but they...
Hi,
I have DC "brushed" (i.e. it has 2 brushes) motor that is rated at 120 VDC. The full-load current is 3 amps. My questions relate to running this motor with a "simple" power supply.
My first shot was to use a single rectifier (half-wave) to rectify the 120 VAC line. The motor runs, but...
So you guys think that switching the 120 VAC will be an improvement, even though the 120 VDC is full-wave rectified? (And does get to zero 120 times per second, I think).
Bill: I guess that the coasting motor will not feed back through the bridge since it would be generating DC?
Jref: Thanks...
Thanks, ScottyUK...
I'm not sure that there is much difference between 120 VAC and full-wave 120 VDC that is un-filtered, pulsing at 120 Hz??
I'll look at the Crydom products.

I have a 120 VDC brushed motor that we have been switching on and off using an Omron G2RL-24-DC12 relay (contacts rated at 8A 250VAC, 8A 30 VDC). The relay contacts have been "sticking" occasionally, presumably from arcing as a result of switching an inductive load. The motor is being driven...
Hi,
I have a DC motor (with brushes) that is designed to be operated on 120 VDC. I am taking the 120 VAC line voltage and rectifying it with a full-wave bridge. What I don't understand is that when I measure the DC voltage across the motor terminals (using a Fluke 87 multimeter on the DC volts...
