US 12,592,594 B2 · Rotor structure, motor structure, and laundry treatment device

Abstract

A rotor structure, a motor structure, and a laundry treatment device are provided. The rotor structure has a rotor iron core, multiple permanent magnets and multiple magnetic barriers. The rotor has multiple permanent magnet slots arranged along a circumferential direction of the rotor core. The permanent magnets are disposed in the permanent magnet slots respectively. The magnetic barriers are disposed on the rotor iron core. The rotor structure can rotate unidirectionally or bidirectionally in the circumferential direction. At least one side of a permanent magnet slot is provided with the magnetic barriers in the rotation direction of the rotor structure. Two ends of each magnetic barrier face towards the permanent magnet corresponding to the permanent magnet slot and towards the outer edge of the rotor core, respectively.

A rotor structure comprising:

a rotor core having a plurality of permanent magnet slots arranged along a circumferential direction of the rotor core;
a plurality of permanent magnets positioned within respective ones of the permanent magnet slots;
and
a plurality of magnetic barriers formed by the rotor core,
wherein, for each permanent magnet slot:
one or more of the magnetic barriers are disposed on at least one side of the respective permanent magnet slot;
a first slot segment of at least one of the one or more magnetic barriers forms a straight-line shape that extends towards the respective permanent magnet slot;
and
a second slot segment of the at least one of the one or more magnetic barriers forms a straight-line shape that extends towards an outer edge of the rotor core.
