Title:
ROTOR STRUCTURE, PERMANENT MAGNET AUXILIARY SYNCHRONOUS RELUCTANCE MOTOR AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/174325
Kind Code:
A1
Abstract:
A rotor structure, a permanent magnet auxiliary synchronous reluctance motor, and an electric vehicle; the rotor structure comprises a rotor main body (10), the rotor main body (10) being provided thereon with a magnetic steel groove set; the magnetic steel groove set comprises outer-layer magnetic steel grooves (11) and inner-layer magnetic steel grooves (12); magnetic conduction channels (13) are formed between the outer-layer magnetic steel grooves (11) and the inner-layer magnetic steel grooves (12), and connection holes (131) are opened on the magnetic conduction channels (13). By means of the connection holes (131) opened on the magnetic conduction channels (13) that are formed between the outer-layer magnetic steel grooves (11) and the inner-layer magnetic steel grooves (12), the deformation of the rotor is effectively lessened during high speed rotation, and the obstruction of magnetic flux by the connection holes (131) of the rotor may also be prevented, thus improving the efficiency of the motor.
