Rotor structure, wheel hub motor and vehicle

Abstract

The embodiment of the application provides a rotor structure, a wheel hub motor and a vehicle. It relates to the technical field of vehicles. The rotor structure comprises a shell, a fixing assembly and a plurality of magnetic steels. An installation groove is arranged on the inner side wall of the shell. The magnetic steels are arranged on the inner side wall of the shell in the circumferential direction of the shell, and the bottom of each magnetic steel is inserted into the installation groove and abuts against the side wall of the installation groove. The fixing assembly is detachably connected to the inner side wall of the shell, and the fixing assembly abuts against the magnetic steels to limit the magnetic steels from sliding out of the installation groove. The rotor structure is used to reduce the loosening of the magnetic steels in vibration.
