MOTOR CONTROLLING SYSTEN AND MOTOR CONTROLLING METHOD

摘要

A motor control system according to an embodiment of the present invention includes: a vehicle controller which generates a torque command; an inverter which generates the maximum reverse magnetic flux, measures a current temperature of a motor, generates a compensation temperature by adding a correction temperature to the measured current temperature of the motor, and generates a current command by substituting the maximum reverse magnetic flux and compensation temperature on a current map per temperature; and a motor driven by the inverter. The compensation temperature is generated by using a reverse electric intensity constant of the motor at 90° and a reverse electric intensity design value at 90°.
