DC motor, power supply question
#5
Quote:The data plate shows the motor as 24VDC 39 amps which as far as I can tell is almost a 1000 watts. I thought a power supply and speed controller would be easy to find and relatively cheap but that doesn't seem to be the case. I don't need the full 1HP as the original motor on the Benchmaster was 1/2HP, can I get away with say a 24VDC 600amp power supply? if so, what would the peak HP be at that rating?

If you have a 24V 600A power supply you don't need to worry about a half a horse! I'm assuming (dangerous, I know) that you were thinking 600 watts, not amps.

DealExtreme.com has a lot of power supplies and you can probably find a 24V 40A supply there pretty cheap. I just received a 12V 20A supply for my induction heater today, it cost me about $30 with free shipping. Also got some stepper drivers pretty cheap. Still waiting on the speed control for the mini-lathe (also cheap), should be here any day. It shipped a day or so later.

As to running it on half current, I'm not too sure that would work out so well. Seems the startup inrush would exceed the 20A rating.
