P0C03 Meaning

When three-phase alternating current flows through the three-phase windings of the stator coil, a rotating magnetic field is generated in MG2. The system controls the rotation of the magnetic field based on the rotor’s rotation position and speed. As a result, the permanent magnets provided in the rotor are pulled in the direction of rotation, generating torque. The generated torque is almost proportional to the amount of current. The system controls MG2 speed by regulating the frequency of the alternating current. Additionally, the system properly controls the rotating magnetic field and the angle of the rotor magnets to generate high torque efficiently, even at high speeds.
