METHOD AND SYSTEM FOR DETERMINING CORE LOSSES IN PERMANENT MAGNET SYNCHRONOUS MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a method and system for determining core losses in a permanent magnet synchronous motor.SOLUTION: A method and system for determining core losses in a permanent magnet synchronous motor comprises measurement of the losses of the motor not connected to a load, and deduction of the core losses of the motor from the losses of the motor. The motor is placed in an over-fluxing state during the measurement of the losses.SELECTED DRAWING: Figure 1
