Hi guys picked up a motor of ebay think it came from a golf cart or granny wagon lol
fair size any how connected the motor to a car charger to test it out works fine
24v = 2100 rpm ish not realy shure what the voltage for this motor should be as the specs have come off the sticker

i adjusted the pot on me speed controller right down on max speed which gave me
0-100volts used a meter to mark 24v on the knob
was hopeing to use my mills speed controller to drive this motor but when i connected
the motor it sounded rough cogging and rotating very slow also adjusted the torque setting right down and slowley raised a little no joy any ideas guys

open the motor to check the bearings and found one the the brush wires had come off the motor has 4 brushes
now at 24v i get 3000 rpm also noticed that the charger is showing the motor drawing 10 amp
