alright, I have a DC gearmotor, rated 90v coil (maximum rating 130v, goes faster with 110 rather than 90, but don't want to push it close to 130) with a 0.60amp requirement. at the time I got it, I read a schematic that called for line voltage, a rectifier (yanked from old PC power supply) two smoothing caps (also from PC power supply) and a dimmer switch before it all to vary the power. well, I think it was a stupid idea to do it that way. it works, but only after I turn the dimmer up a bit. I know, safety first and isolation transformers, but it is built into the grounded PC power supply case. but I can't in my right mind allow this to go this way because I feel its unsafe and unstable.
I need to take 110v house current, and if possible find a (1:1?) isolation transformer, rectify to DC, smooth out with more reliable or better suited caps, regulate the power to something cleaner than the jagged power I am getting now (sometimes when I start it up the motor bucks, and on lower power it moves, stops, moves, stops, doing that until I increase power). I would also like to trade the dimmer switch for something a bit cleaner if possible. for the life of me cant find a good schematic and or parts to do so.
any good advice short of buying a commercial motor control or power supply?
