what possible checks could be carried out to see if a 1HP dc motor is functioning correctly?
The motor is fitted to a running machine and is tripping the control circuit on over current.
As the brushes where creating a lot of sparks i have cleaned the commutator which seemed to cure the over current problem, until the machine had been used a couple of times then the same problem occured.This did not make sense as i thought the higher ressistance between brushes+commutator connection the lower the current draw?
The over current device is set to 7 amps.
The belts driven by the motor are all set up fine.
ps what am i reading if i use a ac clamp ammeter on a dc source?
