Rexroth servo drive and SEW motor


Thread Starter


Running an inverter duty 3 phase motor with Rexroth indramat servo controller.

Old motor still runs but is worn. New motor, 3rd try, will not run. The replacement is supposed to be the same as original. So, after three motors, is it a drive problem or is there something we are missing with the motor? As stated, the original motor still runs, it's just worn, bearings have been replaced, but motor is worn. This is three phase only application, no feedback to controller. Thanks for any help.
