Title:
ROTOR STRUCTURE, PERMANENT MAGNET AUXILIARY SYNCHRONOUS RELUCTANCE MOTOR, AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/174314
Kind Code:
A1
Abstract:
Disclosed are 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) being provided with an inner-layer permanent magnet slot (11) and an outer-layer permanent magnet slot (12), wherein a magnetic conductive channel is formed between the inner-layer permanent magnet slot (11) and the outer-layer permanent magnet slot (12); the cross-section, in a radial direction of the rotor body (10), of the inner-layer permanent magnet slot (11) is of a U-shaped structure; and the cross-section, in a radial direction of the rotor body (10), of the outer-layer permanent magnet slot (12) is of a V-shaped structure. The above technical solution can effectively improve the material utilization rate of the rotor, and also effectively improves the efficiency of an electric motor having the rotor structure.
