Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0031] It should also be noted that the orientation terms such as left, right, up, down, top, and bottom in the following examples are only relative concepts or refer to the normal use status of the product, and should not be ...

Abstract

The invention belongs to the field of motors and particularly discloses a motor magnetic ring, a motor and a washing machine. The motor magnetic ring is composed of a hollow inner hole, a metal bracket fittingly matched with a rotating shaft, and a non-metallic magnetic ring formed on the metal bracket through the injection molding process. The metal bracket comprises a substrate, a sleeve convexly arranged at the middle part of the substrate, and an annular convex edge convexly arranged at the outer edge of the substrate. The hollow inner hole penetrates through the sleeve and the substrate. The non-metallic magnetic ring is formed on the annular convex edge and the substrate through the injection molding process. According to the technical scheme of the invention, the non-metallic magnetic ring and the rotating shaft do not directly match each other. Meanwhile, the non-metallic magnetic ring is formed on the annular convex edge and the substrate through the injection molding process. In this way, when the motor magnetic ring is to be installed onto the rotating shaft, no outwardly expanding stress is applied onto the non-metallic magnetic ring. Therefore, the non-metallic magnetic ring is free from cracking. During the rotating process of the rotating shaft, the centrifugal force applied onto the non-metallic magnetic ring is transferred onto the annular convex edge. As a result, the condition that the motor does not run due to the cracking / shedding state of the non-metallic magnetic ring is avoided.

Description

technical field [0001] The invention belongs to the field of motors, and in particular relates to a magnetic ring of a motor, a motor with the magnetic ring of the motor and a washing machine with the motor. Background technique [0002] The magnetic ring of the motor is mainly used for the detection of the control circuit board to determine the position of the rotor magnetic pole, and it is mainly used in the brushless DC motor or the permanent magnet synchronous motor of the inner rotor. Specifically, when the brushless DC motor or the permanent magnet synchronous motor is working, the control circuit board mainly energizes the stator winding, and the magnitude and direction of the current passed are related to the position of the rotor magnetic pole. When the rotor magnetic pole is at a specific position, the stator winding needs to pass a current with a specific direction and a specific magnitude that matches it, so that the brushless DC motor or permanent magnet synchro...
