Problems solved by technology

However, this method is not only difficult to control the coating amount of lubricant, but also it is very difficult to apply uniformly
In addition, the lubricant is easy to absorb dust, foreign matter, etc., so there are big problems in use
In addition, attempts have been made to directly disperse polyethylene wax, polytetrafluoroethylene (PTFE) powder, etc. in the varnish to improve lubricity, but these lubricants are difficult to uniformly disperse in the varnish, and the uneven lubricity caused by this inhomogeneity is also a problem. issues that need resolving

Embodiment Construction

[0016] The present invention will be further described below through the following embodiments. It should be understood that the following embodiments are only used to illustrate the present invention, not to limit the present invention.

[0017] A self-lubricating polyamide-imide varnish according to one embodiment of the present invention includes a polyamide-imide resin, a bismaleimide compound, and a lubricant.

[0018] The lubricant in the self-lubricating polyamide-imide varnish can improve the lubricity, and the bismaleimide compound can make the lubricant penetrate into the film formed by the self-lubricating polyamide-imide varnish (hereinafter also referred to as "self-lubricating") Insulation film", "film") surface, thereby further improving the lubricity of the film.

[0019] The polyamideimide used as the base resin is not particularly limited, and polyamideimides obtained by conventional methods, such as polyamides obtained by directly reacting tricarboxylic anhy...

Abstract

The invention relates to a self-lubricating polyamideimide varnish, an insulating coating, an insulated wire, a coil and a motor. The self-lubricating polyamideimide varnish comprises polyamideimide resin, a bismaleimide compound and a lubricant, wherein the bismaleimide compound accounts for 10-200% by weight of the polyamideimide resin, and the lubricant accounts for 0.5-10% by weight of the polyamideimide resin.

Description

technical field [0001] The invention relates to a self-lubricating polyamide-imide varnish, an insulating film, an insulated wire, a coil and a motor. Background technique [0002] In recent years, with the downsizing and higher output of electric motors, it is desired to downsize the coil itself so that many insulated wires can be accommodated in a limited space. An insulated wire generally includes a conductor and an insulating film formed on the outer peripheral surface of the conductor. Therefore, there is a problem in that the insulated wire is easily damaged due to contact with the jig during loading, and an interlayer short circuit defect is likely to occur. In order to solve this problem, attempts have been made to reduce the coefficient of friction of the film, one of which is to apply lubricating oil to the surface of the film. However, in this method, it is not only difficult to control the coating amount of the lubricant, but also it is very difficult to apply ...
