Vacuum encapsulating technology method of motor stator notch

Abstract

The invention discloses a vacuum encapsulating technology method of a motor stator notch, which is characterized by adopting pouring sealant with composite components. The method comprises the following steps: before each component sealant in the pouring sealant with the composite components is mixed and stirred, firstly, pouring each component sealant in the composite sealant into a stirring container; then, sealing the container, vacuumizing, stirring each component sealant in the container in vacuum, and preventing air from dissolving in the pouring sealant with the composite components during stirring; and encapsulating completely mixed pouring sealant with the composite components into a stator notch area in vacuum by a pipeline for vacuum encapsulation. The invention is a vacuum encapsulating technology of a motor stator notch, and the technology is characterized in that the function of the technology can completely reach the encapsulation requirements of a megawatt-grade motor stator notch, and no air bubbles exist in the composite sealant and external surface.

Description

technical field [0001] The invention relates to a manufacturing process of a motor stator, in particular to a vacuum potting process for notch insulation of a motor stator. The motor stator notch vacuum potting process of the present invention can meet the requirement of megawatt-level stator notch potting. Background technique [0002] During the operation of the motor, the stator winding of the motor is loosened due to mechanical vibration and electromagnetic vibration, resulting in inter-turn or inter-wire friction and insulation damage, especially when the motor is working in a harsh environment with a lot of water, oil, and dust. The situation is complicated, and it is easy to cause accidents due to insulation breakdown of the stator winding of the motor. Therefore, it is necessary to perform notch filling and sealing work on the production stator to seal the notch part. At present, the filling and sealing of the stator winding slot of the motor is mostly carried out w...
