Laminated sheet metal core for electric machines - has several metal sheets with shaped granules embedded in adhesive emulsion

摘要

A laminated sheet metal body is partic. for electric machines. It is used as sheet metal laminations for stators, pole pieces, and laminated rotor rims. it is designed to provide means for transferring tangential force in the rotor. Several metal sheets (1) with specially shaped elements, or granules (2) contained in an adhesive emulsion, are provided. Alternative systems may be provided to increase the coefficient of friction of at least one surface of the sheet metal. Specially shaped elements may be used with protrusions or indentations such as pits or crimpings that are brought out onto the sheet metal surface.
