On a lark I picked up a treadmill motor on ebay...I actaully can use it for a number of differenet things. Motor is in good condition.. and will rotate with a 1.5 v AA battery...can't stop it manually with a 12 volt source
Specs.
Baldor model # MR10235 you won't find anything else about it on the net.
0- 90 VDC
Brushed ( Checked brushed they are fine)
21 AMP
2 HP
2500 rpm
TEFC case (totally enclosed fan cooled)
weighs about 40 lbs
What is unusual is that this is not a 130 to 180v motor at the 2 hp rating, rather a 90v , so finding a power supply at 90V that goes to 21 Amps could be fun if used for anything else other than a generator.
I will mount the motor in test bench, probably this weekend and see what I get out of it... if not to anything useable for a wind gen at 12v, then maybe build a motorized bar stool with it ( with 3 or 4 U1-3 batteries)
Its items like this that keep my wife puzzled why she married me.
