A resolver phase calibration system comprises a reference pulse generation unit, a resolver-to-digital converter (RDC), and a calibration phase calculating unit. The reference pulse generation unit is configured to generate a reference pulse signal based on a back electro-motive voltage signal of a motor. The RDC is configured to convert output signals of a resolver to a pulse signal, to count pulses of the converted pulse signal, and to output a digital output signal corresponding to a number of the pulses. The calibration phase calculating unit is configured to calculate a calibration phase of the resolver based on the reference pulse signal from the reference pulse generation unit and the digital output signal from the RDC.
