Title:
ROTOR STRUCTURE, PERMANENT MAGNET AUXILIARY SYNCHRONOUS RELUCTANCE MOTOR AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/174323
Kind Code:
A1
Abstract:
A rotor structure, a permanent magnet auxiliary synchronous reluctance motor and an electric vehicle. The rotor structure comprises a rotor body (10). The rotor body (10) are provided with permanent magnet slot sets, each permanent magnet slot set comprising an outer permanent magnet slot (11) and an inner permanent magnet slot (12), and an magnetic conduction channel (13) being formed between the adjacent outer layer permanent magnet slot (11) and the inner layer permanent magnet lot (12). At least one end of the magnetic channel (13) is formed with a deflection section, and the distance from the deflection section to the quadrature axis of the rotor body (10) gradually decreases in the radial outward direction, so that the end of the magnetic conduction channel (13) is provided close to the intersection axis. The technical solution optimizes the magnetic circuit of the rotor structure, improves the reluctance torque of the motor, and further improves the shape of the permanent magnet slots, so that the overall anti-demagnetization capability of the rotor permanent magnet is improved, the motor torque ripple is reduced, the vibration and noise of the motor are reduced, and the anti-demagnetization capability of the electric motor is improved.
