Carrier tooth for use in e.g. adjusting- or drive motor, for receiving wounded coil in motor car, has wounded coil arranged in front side of tooth, and heat conducting thermal film arranged on side surface of tooth

摘要

The tooth (1) has a wounded coil arranged in front side (4) of the tooth, and a winding carrier (5) formed as a separator component, where the carrier is made of plastic material. A heat conducting thermal film (3) i.e. thermal silicon film, is arranged on a side surface (2) of the tooth, where thickness of the tooth is greater than that of the winding carrier. The thermal film is arranged transverse to a longitudinal axis of the tooth. The thermal film and winding support are adjoined to each other, where thermal conductivity of the thermal film is about 2 W/mK to 3.5 W/mK. An independent claim is also included for an electrical machine comprising a stator.
