Motor stator

Abstract

The invention discloses a motor stator which comprises an iron core, a coil and a framework, wherein a through hole is formed in the center of the iron core, and a plurality of wire slot bodies convenient to wind the coil are formed in the inner wall of the framework. The motor stator is characterized in that the framework is subjected to integral injection molding and is molded in the through hole of the iron core. A plurality of threading grooves convenient for threading are formed in the edge of the obverse side of the framework, and a wiring slot used for containing a coil leading-out wire is formed in the reverse side of the framework. The framework of the stator is integrally molded, so that the motor stator is simple in structure and saves mounting process. The motor stator has the advantages of improving the motor performance and reducing damage of enameled wires during operation. The motor stator belongs to the technical field of motors.

Description

Technical field [0001] The invention belongs to the field of motor technology, and more specifically, it relates to a motor stator. Background technique [0002] The stator is the stationary part of the motor. The stator consists of three parts: a stator core, a stator winding and a base. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by the lines of magnetic force in the rotating magnetic field to generate (output) current. [0003] The stator is usually mainly composed of iron core, coil, skeleton and so on. The current stator structure has the following defects: [0004] 1. The frame is divided into two parts, the left half and the right half, which are inserted into the core and installed in the core. Because the thickness of the left half and the right half is thicker, the winding amount of this part will be less compared with other parts. , The winding utilization rate of the same size skeleton is ...

AI Technical Summary

Problems solved by technology

[0004] 1. The skeleton is divided into two parts, the left half and the right half, which are inserted and installed inside the iron core. Since the thickness of the left half and the right half is thicker, the winding amount of this part will be less than that of other parts. , the utilization rate of the bobbin winding of the same size is low, and the power will be smaller

[0005] 2. When the left half and right half of the skeleton are installed and combined, there will be certain errors during installation. There will be a certain gap between the left half and the right half of the skeleton, which will easily cause contact between the enameled wire and the iron core in the gap. If the enameled wire is damaged, Then it will cause the phenomenon of motor breakdown and so on.

[0006] 3. The skeleton is formed separately from the left half and the right half, and then assembled together in the iron core at the same time. The installation is more complicated, and it is impossible to accurately control the exact position of the left half and the right half relative to the iron core, which will easily cause assembly failure and reduce the product quality. Pass rate

[0007] 4. The edge of the frame is closed. When threading, it needs to be wound on the frame from above the edge of the frame to interfere with the winding process; after winding, the lead wire of the enameled wire is wound around the bottom of the frame. It is easy to cause damage to the enameled wire, and the damaged enameled wire contacts the iron core, causing motor breakdown and other phenomena.
