P0C64 Meaning

A resolver is a sensor used to detect the position of magnetic poles in a motor-generator rotor. Knowing the pole position is essential for precise control of MG2 and MG1.

Each resolver contains a stator with an excitation coil and 2 detection coils (S, C). The gap between the stator and rotor changes when the rotor rotates because the rotor is oval-shaped. Alternating current with a predetermined frequency flows through the excitation coil, and the S and C detection coils produce alternating currents according to the sensor rotor position.

The inverter with converter (MG ECU) detects the absolute rotor position based on the phases of the S and C detection coils and their waveform amplitudes. Additionally, the CPU calculates the amount of position change over a predetermined time period to use the resolver as a speed sensor.

The MG ECU monitors signals from the motor resolver and detects malfunctions.
