PERMANENT MAGNET MOTOR ROTOR AND PERMANENT MAGNET SYNCHRONOUS MOTOR

WIPO Patent Application WO/2016/192581

A1

Disclosed are a permanent magnet motor rotor (110) and a permanent magnet synchronous motor (100). The permanent magnet motor rotor (110) comprises: a rotor core (111); tangentially magnetized main-pole permanent magnets (112); and tangentially magnetized auxiliary permanent magnets (113), wherein the main-pole permanent magnets (112) are disposed in a radial direction of the rotor core (111), the number of the main-pole permanent magnets (112) is equal to the number of poles of the permanent magnet synchronous motor (100), the main-pole permanent magnets (112) are uniformly distributed in a circumferential direction of the rotor core (111), and surfaces closest to any two adjacent main-pole permanent magnets (112) have the same magnetic pole; the auxiliary permanent magnets (113) are disposed in the radial direction of the rotor core (111) and the auxiliary permanent magnets (113) are located between any two adjacent main-pole permanent magnets (112), in order to achieve the purpose that the operating points of the main-pole permanent magnets (112) are improved to thereby enable an improvement in the demagnetization resistance of the main-pole permanent magnets (112) and also a reduction in demagnetization risks.
