Title:
ROTOR STRUCTURE, PERMANENT MAGNET AUXILIARY SYNCHRONOUS RELUCTANCE MOTOR, AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/174327
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 the rotor body (10) is provided with a permanent magnet slot set comprising multiple layers of permanent magnet slots comprising a first permanent magnet slot (11), and the permanent magnet slot (11) comprises a first permanent magnet slot section (111) and a first bent slot (113). A first end of the first bent slot (113) is in communication with a second end of the first permanent magnet slot section (111), a second end of the first bent slot (113) is arranged to extend towards an outer edge of the rotor body (10), the distance from a center point of a side wall of the second end of the first bent slot (113) that is close to the outer edge of the rotor body (10) to a cross point between a geometric center line of the first permanent magnet slot section (111) and the outer edge of the rotor body (10) is A, and the width of an end portion of the second end of the first permanent magnet slot section (111) is M, where 0.6 M ≤ A. This arrangement optimizes the magnetic circuit of the rotor structure, such that the overall anti-demagnetization capability of the rotor structure is effectively improved, and the efficiency of the motor of the rotor structure having this structure is also improved.
