Title:
ROTOR STRUCTURE, PERMANENT MAGNET ASSISTED SYNCHRONOUS RELUCTANCE MOTOR AND ELECTRIC AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2019/214223
Kind Code:
A1
Abstract:
Provided in the present invention are a rotor structure, a permanent magnet assisted synchronous reluctance motor and an electric automobile. The rotor structure comprises: a rotor body, the rotor body being opened thereon with a permanent magnet groove set, and the permanent magnet groove set comprising an inner layer permanent magnet groove and an outer layer permanent magnet groove, wherein the inner layer permanent magnet groove and the outer layer permanent magnet groove are outwardly disposed at an interval in the radial direction of the rotor body; a magnetic separation bridge, a first end of the magnetic separation bridge being connected to a first side wall of the inner layer permanent magnet groove, and a second end of the magnetic separation bridge extending in the radial direction of the rotor body and being connected to a second side wall opposite to the first side wall of the inner layer permanent magnet groove. By providing a magnetic separation bridge within an inner layer permanent magnet, the mechanical strength of the rotor structure may be effectively improved, and the efficiency of a motor having the described structure may be effectively improved.
