Parker does not support rewinding motors in the field on our products, and do not recommend sending 3rd party motors to repair houses to be rewound.
Improperly wound motors at repair houses are a common occurrence. "Improperly Wound" is defined as a motor not being rewound to it's exact specifications on the nameplate. If exact values of inductance, resistance, field current, or voltage ratings are incorrectly implemented into the drive then instability in the control loop can occur. If implemented motor data is incorrect from the actual motor values due to being rewound (by an undefinable margin) then at best that instability causes a decrease in performance and control ability that may not be rectifiable. Worse, entire loss of functionality can occur due to the instability.
We provide this below document as a means of verification of potential motor breakdown or if there are concerns that the motor is not up to specifications.
