Abstract

The invention discloses vacuum drying technology in a motor processing method, which is implemented by the following steps of: pressing a stator coil into a motor shell assembly, pressing a stator shielding sleeve into the stator coil, and performing seal welding; connecting a power supply to an outgoing line of the motor, vacuumizing a sealed motor cavity, electrifying to raise the temperature according to set parameters, and pumping humidity in the motor cavity from a vacuum tube into a vacuum pump at high temperature for exhaust; and after drying, introducing nitrogen for oxidation-resistant protection; and finally injecting glue into a junction box body of the motor for sealing, and curing for 12 hours. The problem of humidity residue in motor processing can be effectively solved.

Description

Technical field: [0001] The invention relates to a processing method for a motor, in particular to a processing method for vacuum drying the motor. Background technique: [0002] At present, there are the following problems in motor processing using conventional technology: [0003] 1. Moisture problem. The stator coil is pressed into the motor housing assembly and there is moisture left in the motor cavity, which makes the stator screen sleeve bulge; [0004] Second, the oxidation problem, the motor is prone to oxidation problems during processing; [0005] Three, the sealing line of the motor junction box body is not good, and moisture will easily enter after a long time; [0006] Fourth, the insulation of the motor is poor, which greatly reduces the service life of the motor. Invention content: [0007] Aiming at various problems existing in the existing motors, the invention provides a processing method for vacuum drying of the motors, and the motors processed by th...
