Problems solved by technology

[0008] Therefore, in the process of insulating the stator windings with the traditional insulation treatment process and process equipment, it is impossible to effectively prevent the liquid insulating varnish from flowing out from the notch (slot wedge) along the radial direction, and from flowing out from the slot along the axial direction. The axial ends of the winding slot flow out, resulting in insufficient filling of the insulating varnish in the stator winding and a large number of gaps, especially the small amount of paint on the surface of the ferromagnetic boundary and a thin paint layer
In the notch part, it is also difficult to form a strict sealing ring on the outer periphery of the slot wedge, resulting in a gap between the slot wedge and the silicon wafer of the core notch, and moisture and water will naturally enter the slot along the debonding gap to destroy the insulation. operation poses safety hazards

Abstract

The invention discloses process equipment and method for sealing and curing after liquid filler impregnation of a motor armature. The process equipment comprises a cylinder, an air flow supply device,an armature end part choking device and an infrared cylinder, wherein the armature end part choking device is arranged in the cylinder and is arranged below a to-be-cured winding, first air flow received by the air flow supply device is used for impacting an armature end arranged below the winding from bottom to top so as to form pressurization sealing on the armature end, the infrared cylinder is vertically arranged in an inner cavity of the winding, an upper end and a lower end of the infrared cylinder are opened, and an annular passage is formed between the infrared cylinder and an inner side of the winding.

Description

technical field [0001] The present invention relates to the field of motor technology, in particular to a process and process equipment for sealing and solidifying the liquid filling material of the motor armature after impregnation, more specifically, the present invention relates to a sealing method and a method for preventing liquid from flowing out from gaps of various tissue parts Synergistic curing device. Background technique [0002] Wind energy is one of the cleanest, non-polluting renewable energy sources. Utilization of wind power generation has increasingly become the main form of wind energy utilization, and is highly valued by countries all over the world. A wind turbine is a large-scale power generation device that converts wind energy into electrical energy. [0003] As the core component of the wind power generating set, the motor includes a rotor and a stator, and the stator includes a stator core and a winding wound on the stator core. Such as Figure 1...
