An alternating-current motor control apparatus includes an inverter unit, a current-command divider, a current controller, a torque-variation calculator, and a phase angle generator. The current-command divider is configured to divide a command current amplitude into command current components based on a phase-angle command value that is a sum of the phase angle and an alternating current signal. The torque-variation calculator is configured to calculate a motor electric power based on the command voltage and either the motor current or the command current components and to calculate a torque variation based on the motor electric power. The phase angle generator is configured to generate a phase angle based on the torque variation.

An alternating-current motor control apparatus includes an inverter unit, a current-command divider, a current controller, a torque-variation calculator, and a phase angle generator. The inverter unit is configured to output a command voltage to an alternating-current motor. The current-command divider is configured to divide a command current amplitude into command current components based on a phase-angle command value that is a sum of the phase angle and an alternating current signal. The current controller is configured to control current to match a motor current flowing through the motor with the command current components. The torque-variation calculator is configured to calculate a motor electric power based on the command voltage and either the motor current or the command current components and to calculate a torque variation based on the motor electric power. The phase angle generator is configured to generate a phase angle based on the torque variation.
