Problems solved by technology

[0002] For the clothes treatment device, the performance of the motor installed inside it is an important factor that determines whether the clothes treatment device is good or bad. In the prior art, the requirements for the performance and cost performance of the motor are gradually becoming higher. For the motor, in Under the action of the quadrature axis armature reaction, the magnetic saturation degree of the motor will be deepened, so it can hinder the performance improvement of the motor

Embodiment 1

[0089] Such as Figure 1 to Figure 5 As shown, a rotor structure 100 proposed in this embodiment includes a rotor core and a permanent magnet disposed in the rotor core, so as to be driven under the magnetic action of the permanent magnet, and the rotor structure can rotate relative to the stator. In order to realize the normal operation of the motor. Specifically, the rotor core is provided with permanent magnet slots passing through the two end faces, and the permanent magnets can be arranged in the permanent magnet slots, which facilitates the permanent magnets to be driven by magnetic force. There is also a magnetic barrier on the rotor core. By limiting the extension direction of both ends of the magnetic barrier to the permanent magnet and the outer edge, the magnetic barrier can be used as a structure to relieve the degree of magnetic saturation and form a magnetic barrier during the rotation of the rotor structure. , to increase the power density and torque density of...

Abstract

The embodiment of the invention provides a rotor structure, a motor structure and a clothes processing device, and the rotor structure comprises a rotor iron core which is provided with a plurality of permanent magnet grooves, wherein the plurality of permanent magnet grooves are arranged in a surrounding manner along the circumferential direction of the rotor iron core; permanent magnets arranged in the permanent magnet grooves; and a magnetic barrier which is arranged on the rotor core, wherein the rotor structure can rotate unidirectionally or bidirectionally in the circumferential direction, the magnetic barrier is arranged on at least one side of the permanent magnet groove in the rotating direction of the rotor structure, and the two ends of the magnetic barrier face the outer edges of the permanent magnets and the rotor core respectively. According to the technical scheme, on one hand, on the basis that quadrature axis armature reaction of the motor is restrained, the magnetic saturation degree is relieved, the load counter electromotive force is reduced, and the torque density and the overload capacity of the motor are improved, the position of the magnetic barrier can be set according to limitation of the rotation direction of the rotor structure; and on the other hand, the rotor iron core is hollowed to form the magnetic barrier, so that the use amount of the rare earth permanent magnets can be reduced.
