Introduction of insulation film suitable for use in motors #InsulationFilm

In conventional motors, resin materials were used between the electromagnetic steel plates (iron core) and copper wire (enameled wire) to insulate the copper wire (enameled wire) from the electromagnetic steel plates (iron core). Occasionally, when winding the copper wire around the core, the enamel may peel off, leading to short circuits, which necessitated insulation treatment during the winding process. Subsequently, as the quality of insulation films improved, films such as PET film began to be used to enhance the packing density. Currently, the following films are primarily used as insulation films: PET film, PEN film, PEI film, PI film, and PP film. The main materials for these films include: - Epoxy film - Polyimide film - PTFE film - Acetate cloth - Polyester film - Glass cloth - Glass filament polyester film Each film has its own heat resistance and insulation classification. In the manufacturing of motors, insulation films are used in positions such as the insulation work between the copper wire (enameled wire) and the electromagnetic steel plates (iron core) and during crimping operations.
