Rotor, motor, food processor, air supply device and household appliance

Abstract

The invention provides a rotor, a motor with the rotor, a food processor with the motor, an air supply device and a household appliance. The rotor comprises a rotating disc and a magnetic piece; the rotating disc comprises a first support and a second support; the first support and the second support define a containing space, and the magnetic piece is arranged in the containing space. The first support and the second support are used for replacing multiple layers of silicon steel sheets, so the first support and the second support are not prone to loosening, the stability of the rotor structure is guaranteed, the first support and the second support are not prone to loosening, and a rotor end ring used for pressing the first support and the second support does not need to be independentlyarranged. Therefore, the weight of the motor is reduced, the thickness of the rotor can also be reduced by accommodating the magnetic pieces in the first bracket and the second bracket, the thicknessof the motor is further reduced, and the light weight and miniaturization of the motor are realized.

Description

technical field [0001] The invention belongs to the technical field of motor manufacturing, and specifically relates to a rotor, a motor, a food processor, an air supply device, a household appliance, an electric vehicle and a power generating device. Background technique [0002] The motor is mainly composed of stator, rotor and end cover. The rotor is composed of magnets and multi-layer silicon steel sheets. There are two common ways to install magnets and multi-layer silicon steel sheets. One is to attach the magnets to the multi-layer silicon steel sheets. On the surface, this method increases the thickness of the rotor, and the magnet is easy to fall off from the multi-layer silicon steel sheet. The other is to embed the multi-layer magnet into the silicon steel sheet. In order to prevent the multi-layer silicon steel sheet from loosening, an additional rotor end ring is required. It is used to compress the silicon steel sheet, which not only increases the complexity of...

[0002] The motor is mainly composed of stator, rotor and end cover. The rotor is composed of magnets and multi-layer silicon steel sheets. There are two common ways to install magnets and multi-layer silicon steel sheets. One is to attach the magnets to the multi-layer silicon steel sheets. On the surface, this method increases the thickness of the rotor, and the magnet is easy to fall off from the multi-layer silicon steel sheet. The other is to embed the multi-layer magnet into the silicon steel sheet. In order to prevent the multi-layer silicon steel sheet from loosening, an additional rotor end ring is required. It is used to compress the silicon steel sheet. This method not only increases the complexity of the process and the production cost, but also increases the weight of the rotor, making it difficult to reduce the weight and miniaturization of the motor.
