I completely understand Jim, I often got that way when I'm tired too. Small permanent magnet DC motors like these hyd. pumps and starters can easily be fed with a higher voltage and run fine, actually better as tm america pointed out. The only coil in a small DC motor like these is the...

trust me tm america, you are changing the coil configuration even in small single phase motors too. If you feed a 120 volt coil with 240 volts you will burn it up. That's why you are putting the coils in a series connection so they can handle the higher voltage. It's the same reason you use...

That's not really the case with AC motors. You said it yourself, you must re-wire an AC motor to make it run on the higher voltage, not the case with the smaller DC motors. Smaller DC motors are still using the same windings and internal configuration, so when you feed it with a higher...
