Permanent magnet synchronous motor skeleton

Abstract

The invention discloses a permanent magnet synchronous motor skeleton which comprises a square inlet slot. A small slot is arranged at the intersection of the adjacent planes of the inlet slot. The small slot is disposed at the corner of the inlet slot so that the first layer of a wrapped enameled wire can be arranged neatly, which facilitates the winding of the subsequent multilayer enameled wires, avoids intermediate wire drums, and reduces defective products.

Description

technical field [0001] The invention relates to the technical field of permanent magnet synchronous motors, in particular to a framework of permanent magnet synchronous motors. Background technique [0002] The skeleton of the traditional permanent magnet synchronous motor is made of nylon material, and the whole is injected with the stator, which can be called an integral skeleton; the nylon material often undergoes certain deformation during processing, resulting in inconsistency in size. It is beneficial to the subsequent processes such as winding and rounding. [0003] With the continuous rapid development of domestic technology in recent years, most of the domestic manufacturers have abolished the original processes and used new materials such as PBT, PBS, ABS, PA66, etc. Make a concave-convex fit to the skeleton at the position. [0004] In recent years, domestic demand for servo motors has also increased year by year, and higher and higher requirements have been put...
