Problems solved by technology

[0004] However, during the actual use of the rotor, due to the large and frequent changes in the ambient temperature, and some mechanical shocks are prone to occur, the insulating paint layer on the surface of the rotor is damaged, such as cracks. Lead to the expansion of damage, and eventually cause the insulation performance of the insulating paint layer to decrease or even fail

Abstract

The invention discloses a self-repairing type insulation treatment process for a motor rotor, and belongs to the technical field of rotors. According to the self-repairing type insulation treatment process, a detection line is doped into a molten raw material, the molten raw material is pre-buried into a parison after being extruded, and then a compressed gas is introduced into a mold to blow up the parison, and due to blow-up stretching of the parison, the detection line is pre-broken so that initiating detection of a spalling phenomenon of the parison is performed. Once the spalling phenomenon occurs, the compressed gas enters the detection line along the spalling area for filling, and then the pre-filled molten raw material is extruded by utilizing the internal expansion action so that the molten raw material is forced to flow out to the spalling area for material supplementation. Good combination with the parison under extrusion action of the compressed gas is realized, the spalling area can be automatically repaired in the blow-up process, on one hand, the spalling area can be prevented from being further expanded, the quality of the product can be improved, and on the other hand, the mechanical strength can be effectively improved through embedding in the product.

Description

technical field [0001] The invention relates to the technical field of rotors, in particular to a motor rotor self-repairing insulation treatment process. Background technique [0002] Generally speaking, the motor rotor is the rotating part of the motor. The motor is composed of two parts: the rotor and the stator. It is used to realize the conversion device of electrical energy and mechanical energy and mechanical energy and electrical energy. The motor rotor is divided into motor rotor and generator rotor, and the motor rotor is divided into two types: inner rotor rotation mode and outer rotor rotation mode. The rotation mode of the inner rotor is that the core body in the middle of the motor is a rotating body, which outputs torque (referring to the motor) or receives energy (referring to the generator). The rotation mode of the outer rotor is to use the outer body of the motor as the rotating body, and different modes facilitate the application in various occasions. ...
