Title:
ROTOR STRUCTURE, PERMANENT MAGNET AUXILIARY SYNCHRONOUS RELUCTANCE MOTOR, AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/174322
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), wherein a permanent magnet slot set is provided in the rotor body (10), the permanent magnet slot set comprises an outer-layer permanent magnet slot (11), and a first air slot (21) is further provided in the rotor body (10); a first end of the first air slot (21) is arranged to be in communication with or adjacent to an end portion of the outer-layer permanent magnet slot (11), and a second end of the first air slot (21) extends towards an outer edge of the rotor body (10) and is arranged to be gradually distanced from a straight axis of the rotor body (10); and if the first end of the first air slot (21) is arranged adjacent to the end portion of the outer-layer permanent magnet slot (11), a first magnetic conductive channel (31) is formed between the first end of the first air slot (21) and the end portion of the outer-layer permanent magnet slot (11). The rotor body (10) is provided with the air slot for deciding the orientation of a rotor magnetic path, so that magnetic flux leakage is reduced during the process in which the stator magnetic field reaches the rotor via an air gap, thereby improving the magnetic field utilization rate, increasing the torque output, minimizing the demagnetization effect of a demagnetization magnetic field on the permanent magnet, and enhancing the anti-demagnetization capability.
