Embodiment Construction

[0020] 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.

[0021] 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.

[0022] Such as figure 1 and figure 2 As shown, the rotor assembly provided by the embodiment of the present invention includes a rotating shaft 1, a first insulating member 4, a second insulating member 5, a rotor core 2 sl...

Abstract

The invention is applicable to the field of motors and discloses a rotor assembly and a motor. The rotor assembly includes a rotating shaft, a first insulating member, a second insulating member, a rotor core and a magnet arranged outside the rotor iron core. The first insulating member is arranged on the rotor iron Between the core and the magnet; the rotating shaft includes a first shaft body and a second shaft body separated from each other, the rotor core includes a first iron core split body and a second iron core split body separated from each other, the first iron core split body and the second iron core split body The two iron core splits are sleeved on the first shaft body and the second shaft body respectively, and the second insulating member includes an axial insulation part arranged between the first iron core split body and the second iron core split body. The present invention solves the problem of electrical corrosion of motor bearings through the insulating effect of the first insulating member and the second insulating member; at the same time, through the connection between the first shaft body and the first iron core split body, the connection between the second shaft body and the second The split connection of the iron core ensures the axial bonding force and radial bonding force between the first shaft body and the second shaft body, and ensures the stable and reliable operation of the motor.

Description

technical field [0001] The invention belongs to the field of motors, in particular to a rotor assembly and a motor with the rotor assembly. Background technique [0002] In order to solve the problem of electrical corrosion of motor bearings, an existing motor is designed in such a way that the rotating shaft is divided into two sections of shaft bodies, and insulating magnets are sleeved on the ends of the two shaft bodies. Although this design scheme can achieve the purpose of insulating the two sections of the shaft body, due to the use of insulating magnets to connect the two sections of the shaft body, the axial bonding force and the radial bonding force of the two sections of the shaft body are relatively small. When running at high speed or high torque, the shaft body is prone to slipping or even slipping, which seriously affects the running stability of the motor, and makes this design scheme only applicable to motors with extremely small power; at the same time, bec...
