Abstract

The invention provides a vacuum potting process. The vacuum potting process includes following steps: performing demoulding processing on a clamp; assembling the clamp; preheating a to-be-potted device; performing multi-segment potting in a vacuum environment; performing curing processing on the potted device; and performing demoulding on the device after completion of potting. According to the vacuum potting process, the device is fully preheated, the viscosity of glue potted into the device can be rapidly reduced, infiltration is guaranteed, and the influence of moisture on the potting effect is avoided; and the multi-segment potting process is performed in the vacuum environment, air in gaps between components in the device can be completely eliminated, the infiltration of the glue intothe gaps can be guaranteed, and bubbles or gaps can be avoided.

Description

technical field

[0001] The invention relates to the field of potting, in particular to a new energy vacuum potting process. Background technique

[0002] The new energy vehicle industry is a strategic emerging industry focused on by the state. Especially after the State Council promulgated policies such as exemption from purchase tax in July 2014, the production and sales of new energy vehicles have continued to blow out; however, due to the complex environment in which new energy motors are used In order to meet the requirements of its extremely high withstand voltage strength, dielectric strength, thermal conductivity and heat resistance, mechanical strength, electrical strength and noise, the usual practice is to impregnate and pot the motor stator. Treatment; although dipping treatment can improve the mechanical strength, thermal conductivity and heat resistance, electrical strength and external environment resistance of the motor stator, it is far from enough for new en...
