Common Insulation Materials for Electric Motors - Films, Composites, Mica and Laminates
Films and composite materials for electrical applications
Several high molecular polymers can be made into films with different properties and uses. Films for electrical use are characterized by thin thickness, softness, moisture resistance, and good electrical and mechanical strength. Commonly used electrical films are polyester film (grade E), polynaphthalene film (grade F), aromatic polyamide film (grade H), polyimide film (grade C), polytetrafluoroethylene film (grade H) ). Mainly used for motor coil wrapping insulation and winding gasket insulation.
Fiber materials, such as insulating paper or varnished cloth, are bonded on one or both sides of the film to form a composite material. Fiber is used to improve the mechanical strength, tear strength and surface stiffness of the film, and is mainly used for slot insulation and interlayer insulation of small and medium-sized motors.
The friction on the surface of the film will generate a strong electrostatic field, which is easy to absorb dust in the air and reduce the electrical performance. Therefore, when the film and its composite materials are processed, the workplace must be kept clean, and the processing equipment should be equipped with static eliminators. Films and composite materials should be stored under the specified temperature and humidity conditions. If the storage period is exceeded, they should be re-examined according to the standard before they can be used.
