摘要： A rotor assembly of a motor is configured to be rotatable relative to a stator. The rotor assembly may comprise a permanent magnet rotor segment comprising permanent magnets, the permanent magnet rotor segment configured to be rotatable by a magnetic field generated by the permanent magnets; and a reluctance rotor segment comprising flux barriers, the reluctance rotor segment configured to be rotatable by magnetic reluctance formed by the flux barriers. The permanent magnet rotor segment and the reluctance rotor segment are axially stacked relative to each other so that at least a part of a first torque ripple generated by the permanent magnet rotor segment and at least a part of a second torque ripple generated by the reluctance rotor segment can cancel each other. The permanent magnet rotor segment may be a rare earth permanent magnet rotor, and the reluctance rotor segment may be a synchronous reluctance rotor.

摘要： The disclosure relates to a steering control device and method. Specifically, according to the disclosure, a steering control device comprises a first steering control module controlling a first reaction force motor to generate a reaction force torque for a steering wheel through a first inverter and a second steering control module controlling a second reaction force motor to generate a reaction force torque for the steering wheel through a second inverter. The first steering control module or the second steering control module generates the reaction force torque by conducting one of the first inverter and the second inverter when the first inverter and the second inverter fail.
