Motor re-rating for traction applications - Field weakening revisited

Abstract

The conventional wisdom in traction applications is to use machines in their field-weakening regime. Here, an alternative approach is given in which field weakening is avoided in an AC drive traction system. Instead, the motor's performance is extended through a reduced voltage re-rate procedure. This yields an extended full-flux regime that permits a given motor to achieve full rated torque and much higher power as its speed range is extended. specific examples for electric vehicle drives are provided.
