Title:
PERMANENT MAGNET ELECTRIC MOTOR ROTOR AND PERMANENT MAGNET ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2021/244478
Kind Code:
A1
Abstract:
Disclosed in the present application are a permanent magnet electric motor rotor and a permanent magnet electric motor. The permanent magnet electric motor rotor comprises: a rotor iron core, V-shaped magnetic steel grooves uniformly provided on the rotor iron core and magnetic steel assembled on the V-shaped magnetic steel grooves. The rotor iron core is provided with magnetic bridge protrusions, and the magnetic bridge protrusions are provided at the positions on the outer sides of the V-shaped magnetic steel grooves close to the q-axis of the rotor. The permanent magnet electric motor rotor optimizes a magnetic circuit of the electric motor and reduces iron loss under various working conditions by optimizing the shape of a magnetic bridge, thereby greatly improving the driving efficiency and the rotating speed of the electric motor and meeting the driving requirements of new energy vehicles.
