Insulating varnish is almost the life of the motor
The motor is inseparable from the insulating paint. The composition and manufacturing technology of the insulating varnish have been continuously updated and improved. The methods and means of promoting the design and manufacture of the motor are also changing with each passing day, which promotes the wide application of high temperature and high power density motors that originally stayed in the design restricted area.
It can be seen from this that the importance of insulating varnish to the motor is not difficult to understand why the motorist's discussion of insulating varnish has always been so talked about. Ms. Join me today to join in the fun, but also to talk to everyone about insulation paint.
Motor insulation paint can be divided into five categories according to the scope of use: impregnating varnish, enameled wire lacquer, covering lacquer, silicon steel lacquer and anti-corona lacquer. Anti-corona paint is generally only used on high-voltage motors.
Impregnating paint
The impregnating varnish is divided into two types: solvent lacquer and solventless lacquer. It is mainly used for impregnating motor windings (stator windings and wound motor rotor windings) to fill the gaps and micropores, and to form a continuous flat surface on the winding surface after curing. The film is cured and cured into a hard whole.
Impregnation and drying are a special key part of the motor production process. The viscosity, fluidity, solid content, dryness and adhesion of the impregnating paint directly affect the final performance of the motor.
