Stator assembly for electric machine e.g. spindle motor having fluid dynamic bearing system, has a pole tooth having windings which are arranged with winding wires that are arranged in vibration-damped manner on the pole teeth

摘要

The stator assembly (34) comprises several pole teeth comprising a stator core (36), in which each pole tooth has windings (38) which are arranged with the winding wires. The winding wires of the windings are arranged in vibration-damped manner on the pole teeth. A viscoelastic material such as rubber or natural rubber is arranged between the pole teeth and the winding wires of the windings. The pole teeth are coated with the viscoelastic material in the region of the windings.
