Introduction of Forming Method of Motor Insulation Paper

With the continuous increase of population and the continuous improvement of people’s economic level, people’s demand for electricity is also increasing, which has resulted in many motor products. In order to avoid accidents in the use of these electrical equipment, various insulation materials have been widely used. Motor insulation paper is one of the commonly used insulation products. Let’s take a look at the forming method of this motor insulation paper.

There are many molding methods for motor insulation paper, including hand lay-up molding, injection molding, fiber winding molding, compression molding, pultrusion molding, RTM molding, autoclave molding, diaphragm molding, transfer molding, reaction injection molding, soft film expansion molding, Stamping, etc.
The forming methods of motor insulation paper can be divided into solid phase forming method and liquid phase forming method.

The former motor insulation paper is formed by applying pressure below the melting point of the substrate, including diffusion welding, powder metallurgy, hot rolling, hot drawing, hot isostatic pressing and explosive welding.
The latter motor insulation paper melts the matrix and fills it with reinforcing materials, including traditional casting, vacuum suction casting, vacuum back pressure casting, extrusion casting, and injection casting. The ceramic-based insulating paper is mainly formed by solid-phase sintering , Chemical vapor infiltration molding, etc., chemical vapor deposition molding, etc.
The above has described in detail the molding methods of motor insulation paper: solid phase molding method and liquid phase molding method. I believe everyone can have a simple understanding of the forming of motor insulation paper. In addition, it should be noted that the forming method of the motor insulation paper should have different choices according to different substrates in order to exert its normal insulation effect.
