Title:
ROTOR STRUCTURE, PERMANENT MAGNET ASSISTED SYNCHRONOUS RELUCTANCE MOTOR, AND ELECTRIC CAR
Document Type and Number:
WIPO Patent Application WO/2019/174315
Kind Code:
A1
Abstract:
A rotor structure, a permanent magnet assisted synchronous reluctance motor, and an electric car. The rotor structure comprises a rotor body (10), which is provided with a permanent magnet slot group, comprising an inner permanent magnet slot (11). The rotor body (10) is further provided with a first bent slot (21) and a second bent slot (22). The first bent slot (21) is in communication with a first end of the inner permanent magnet slot (11), the geometric center line in the length direction of the first bent slot (21) and the geometric center line in the length direction of the first end of the inner permanent magnet slot (11) having a first angle. The second bent slot (22) is in communication with a second end of the inner permanent magnet slot (11), the geometric center line in the length direction of the second bent slot (22) and the geometric center line in the length direction of the second end of the inner permanent magnet slot (11) having a second angle. The first angle and the second angle are of unequal values. Making the values of the first angle and the second angle unequal can optimize the magnetic circuit of the rotor structure, thus increasing the torque of the rotor structure, reducing the effects of torque ripple, raising the resistance of the motor to demagnetization, and improving the efficiency of the motor.
