Tool for coating motor core electrostatic machine with powders and method for coating motor core electrostatic machine with powders

Abstract

The invention relates to a tool for coating a motor core electrostatic machine with powders and a method for coating a motor core electrostatic machine with powders. A motor core comprises an annular core body. The annular core body includes a plurality of core units that can be spliced to each other to form an annular structure. Each of the core units includes a yoke portion and a tooth portion extending in the radial direction from the yoke portion to form the internal teeth of the annular core body. The tool includes a positioning component. The positioning component includes a positioning body. The outer side wall of the positioning body is provided with at least one positioning groove. The shape and size of the positioning groove match those of the yoke portion of the core unit. The yoke portion is engaged in the positioning groove. The tooth portion protrudes from the outer side wall of the positioning body in the radial direction. The tool for coating a motor core electrostatic machine with powders can simplify the powder coating process of the motor core with internal teeth, and improves the powder coating efficiency and precision.

Description

technical field [0001] The invention relates to the field of motor manufacturing, and more specifically relates to a jig for powder coating of a motor iron core electrostatic machine and a powder coating method for a motor iron core electrostatic machine. Background technique [0002] At present, the iron core used in the motor generally needs to coat the contact surface with the coil winding with insulating powder, so as to be insulated from the coil winding. In the prior art, clamps are generally used to clamp the iron core at both ends of the iron core for the iron core with external teeth, and then the assembly is sent to an electrostatic machine for powder coating. However, for iron cores with internal teeth, this method cannot be applied, and it is easy to cause the outer surface of the yoke of the iron core and the inner wall of the teeth to stick to the insulating powder, which affects the use of the iron core. At present, the iron core with internal teeth generally...

Problems solved by technology

However, for iron cores with internal teeth, this method is not applicable, and it is easy to cause insulating powder to stick to the outer surface of the yoke of the iron core and the inner wall of the teeth, affecting the use of the iron core

At present, the iron core with internal teeth generally uses a mask to cover the surface that does not want to be coated, but this method has disadvantages such as cumbersome operation and low efficiency.
