Motor carbon sleeve and motor

Abstract

A motor carbon sleeve disclosed by the present invention comprises an annular main body, the annular main body is formed by combining an upper ring body and a lower ring body, and the upper ring body and the lower ring body are respectively provided with a plurality of embedding teeth and embedding grooves which are matched with each other; the upper ring body and the lower ring body are both formed by splicing a plurality of arc-shaped split bodies, and the split bodies on the upper ring body and the lower ring body correspond to each other in a staggered mode. The motor carbon sleeve disclosed by the invention adopts a split type structure, the upper and lower layers of ring bodies and each layer of ring bodies adopt a split type splicing structure, and the upper and lower layers of ring bodies are in interference fit connection by adopting the embedding teeth and the embedding grooves, so that the split bodies which are arranged in a vertically staggered manner can firmly form a complete annular carbon sleeve main body structure; and the whole assembly is more convenient. In addition, the heat dissipation holes, the elastic piece mounting holes and the stator lead penetrating holes are formed in the split bodies, so that the motor carbon sleeve is easier to process, the processing difficulty is reduced, and the production efficiency and the production cost are remarkably reduced.
