Abstract

The invention provides a magnet separator and a motor. The magnet separator includes a first joint part configured to extend along a first axis, and a second joint part which is configured to extend along a second axis and configured to be integrally formed with the first joint part, wherein a preset angle is formed between the first axis and the second axis; the shape of the first joint part is configured to be matched with the shape of a concave part in a motor rotor; and the shape of the side surface of the second joint part is configured to be matched with the shape of the side surface of a motor magnet. The magnet separator and the motor have the advantages of being simple, reliable, easy to implement, convenient to use and the like, automatic and rapid assembly of the motor can be achieved, and meanwhile good mechanical stability is provided.

Description

technical field [0001] The present application relates to the field of electrical machine construction. More specifically, the present application relates to a magnet spacer intended to provide convenient and flexible assembly of motor magnets. The present application also relates to an electric machine comprising the above-mentioned magnet spacer. Background technique [0002] For a motor in which a stator is mounted on a motor axis and a rotor is arranged to rotate around the motor axis, motor magnets need to be mounted to the rotor in the circumferential direction of the rotor. For example, a plurality of motor magnets may be arranged on a certain cross-section of the rotor. Existing motor magnets are usually fixed by means of glue and mechanical fixation. Glue can be an adhesive that needs to be cured at high temperature, while mechanical fixation is usually achieved with components such as bolts. [0003] However, existing magnet fixing solutions are disadvantageous...
