DTC P0A90-00: Drive Motor "A" Performance [12/2019 - 11/2023]: Description
WARNING: This page is about a different variant/trim than selected.
When three-phase alternating current flows through the three-phase windings of the stator coil, a rotating magnetic field is generated in the motor (MG2). The system controls the rotation of the magnetic field in accordance with the rotating position and speed of the rotor. 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 motor speed by regulating the frequency of the alternating current. Furthermore, the system properly controls the rotating magnetic field and the angle of the rotor magnets in order to generate high torque in an efficient manner, even at high speeds.
