Title: MOTOR CONTROL METHOD AND MOTOR CONTROL DEVICE
Abstract:
A method for controlling a motor provided with a plurality of windings each having a phase, the method comprising: an estimation step for estimating the maximum temperature of the winding that reaches the highest temperature among the plurality of windings each having a phase, in accordance with the magnitude of input power that is input to the motor; and a limiting step for limiting the input power on the basis of the maximum temperature estimated in the estimation step, said estimation step and said limiting step being implemented when the motor is in low rotation mode.
