Title:
ROTOR AND MOTOR HAVING THE ROTOR
Document Type and Number:
WIPO Patent Application WO/2020/145220
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a rotor and a motor having the rotor. The rotor includes a rotor core that rotates about a central axis and is composed of electromagnetic steel plates laminated along an axial direction. The rotor core includes a plurality of flux barriers penetrating through the electromagnetic steel plates along the axial direction, and a permanent magnet is accommodated in at least one of the flux barriers. An end cap assembly covering at least a part of the rotor core is respectively disposed at two axial ends of the rotor core. The end cap assembly includes at least two end caps separately disposed along a circumferential direction. In the embodiments of the present invention, the end cap does not impede installation of the permanent magnet, so that more permanent magnets can be installed into the flux barrier, thereby improving output efficiency of the motor.
