Abstract
A motor control method of the present invention is a motor control method for controlling, by a voltage phase control, an applied voltage applied to a motor via an inverter. The control method includes: calculating a phase command value to be used for the voltage phase control by a feedforward control based on a torque command value to the motor; calculating an amplitude command value to be used for the voltage phase control, based on a drive voltage for the inverter; calculating a voltage command value to the motor based on the phase command value and the amplitude command value; and a voltage application step of applying the applied voltage from the inverter to the motor based on the voltage command value.
