DC motor controller

Hi Bill,

I found this at surpluscenter...

http://www.surpluscenter.com/item.asp?UID=2006111113404127&item=11-2269&catname=electric

Be sure to click on the grey tabs that say "more specs" and "wiring".

Hooked up to 110AC your treadmill motor(like mine) would run at 90VDC.
It controls the speed, gives you your DC Voltage, and you can load
it to 5 amps as is before heat trouble sets in. You can add heatsinks
to go up to 10 amps. 90 volts x 10 amps = 900 watts, thats around
1.25 HP.

Depending on what you want to use the motor for, this may or may
NOT be a good solution. I hope someone will jump in here so
Bill doesn't get steered wrong.

John
