Document Type and Number:
WIPO Patent Application WO/2023/000735
Kind Code:
A1
Abstract:
The present application discloses a motor rotor, a permanent magnet synchronous motor, and a vehicle. The motor rotor comprises a rotor iron core and magnetic steel mechanisms; each magnetic steel mechanism comprises a magnetic steel body; the magnetic steel body comprises a bushing and a plurality of magnetic steel pieces; accommodating grooves are formed on the rotor iron core; the bushing is mounted in each accommodating groove; the bushing comprises a plurality of magnetic conduction plates arranged at intervals; the plurality of magnetic conduction plates divide the bushing into a plurality of mounting grooves that are sequentially arranged along the extension direction of the bushing; and the number of the mounting cavities is consistent with the number of the magnetic steel pieces, and one magnetic steel piece is mounted in each mounting cavity.
