PURPOSE: An apparatus and a method for measuring a phase of a resolver phase calibration system are provided to easily mount the resolver and to easily control speed and torque of a motor by automatically correcting a phase difference of the resolver. CONSTITUTION: A phase of resolver phase calibration system measuring apparatus includes a battery(10), a battery management system(20), an inverter(30), a safety disconnect unit(40), an MCU(50), a motor(60), a resolver(70), a reduction device(80), a differential device(90), and a driving wheel(100). The battery(10) stores electric energy required for operating an electric vehicle and supplies the electric energy to a driving source, that is, to the motor(60). The battery management system(20) monitors temperature, ambient temperature, state of charge, and voltage/current of the battery(10). The inverter(30) feeds power to the motor(60) by converting DC power into AC power.
