1. A motor apparatus, comprising:
a motor;
an inverter, used to convert an input voltage into a three-phase alternating current voltage and provide the three-phase alternating current voltage to the motor;
an inverter controller, used to control the inverter; and
a rotation angle sensor, fixed to the motor, used to detect a rotation angle of the motor,
wherein the inverter controller comprises a calculator, and the calculator calculates an offset angle of an installation position of the rotation angle sensor according to a difference between a measured value and a theoretical value of a voltage phase of the motor.
