Embodiment Construction

[0031] 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.

[0032] 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.

[0033] 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 is applicable to the field of motors, and discloses a motor magnetic ring, a motor and a washing machine, wherein the motor magnetic ring includes a non-metallic magnetic ring sleeved on a rotating shaft and a metal sleeve sleeved on the non-metallic magnetic ring, and the non-metallic magnetic ring It includes a mounting part for matching with the rotating shaft sleeve and a magnetic ring working part located at one axial end of the mounting part and used to generate a magnetic field for detection by the control circuit board. The metal sleeve is sleeved on the mounting part. In the present invention, the non-metallic magnetic ring is axially divided into two parts: the installation part and the magnetic ring working part, and the installation of the non-metallic magnetic ring on the rotating shaft is realized through the installation part, and the magnetic field is generated by the magnetic ring working part for detection by the control circuit board In this way, the position of the magnetic poles of the rotor can be determined; at the same time, by installing a metal sleeve outside the installation part, there is no risk of cracking at the installation part of the non-metallic magnetic ring and the working part of the magnetic ring, thereby preventing the damage caused by the non-metallic magnetic ring. If the ring breaks or falls off, the motor will not work.

Description

technical field [0001] The invention belongs to the field of motors, in particular to a motor magnetic ring, a motor with the motor magnetic ring 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 synchronous motor can continue t...
