Problems solved by technology

[0005] The purpose of the present invention is to provide a stator heating method, which can reduce the heating time of the stator, efficiently and uniformly preheat the stator to a fixed temperature range, improve the heating efficiency of the stator, and further improve the production quality and production efficiency of the stator It solves the problem that there is no preheating of the stator at present, and it takes a long time to cure the resin, so that the fluidity of the resin will be significantly deteriorated during molding, which may cause defects such as unfilled, thereby reducing the production quality of the stator

Embodiment 1

[0029] A stator heating method, the method comprising the steps of:

[0030] (1) Preheating process: first roughen the surface of the stator, then clean and dry the stator to remove the moisture attached to the end of the stator coil, and the stator will be used after preheating. The temperature is 80-100°C, and the heat treatment time is 1h. The preheating method is to arrange a high-frequency induction coil near the coil end of the stator, and then energize the induction coil to perform high-frequency induction heating on the stator, which can make many high-frequency magnetic force lines pass through. Coil ends to enable uniform heating of the stator;

Abstract

The invention discloses a stator heating method. The method comprises the following steps of firstly, roughening the surface of a stator, then cleaning and drying the stator, removing moisture attached to the end part of a stator coil, preheating the stator for later use, adding a resin material into a plastic extruding machine, and extruding molten resin through the plastic extruding machine, adding a proper amount of diluent into the resin in the molten state. The method is advantaged in that the heating time of the stator can be shortened, the stator can be efficiently and uniformly preheated to a fixed temperature range, the heating efficiency of the stator is improved, the production quality and the production efficiency of the stator can be further improved, and the problems that thestator is not preheated at present, resin needs to be cured for a long time and production cost is high are solved; fluidity of the resin is obviously worsened during molding, and the defects of unfilling and the like are possibly caused, so the production quality of the stator is reduced, and the service life of the stator can be prolonged.

Description

technical field [0001] The invention relates to the technical field of stator production and processing, in particular to a stator heating method. Background technique [0002] Asynchronous motors, also known as induction motors, are composed of casings, end covers, stators, rotors, bearings, etc. The stator is the stationary part of the motor or generator. It is composed of a frame, stator core and stator windings. The rotor is the motor The rotating part of the rotor, including the rotor core, rotor winding and shaft and other parts. 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 magnetic force lines in the rotating magnetic field to generate current. The asynchronous motor generates electromagnetic torque through the interaction of the air gap rotating magnetic field and the induced current of the rotor winding, thereby realizing the conversion of electromechanical energy into mechanical ...
