ABSTRACT:
In an electric motor, for example as used in audio or video apparatus, the rotor comprises a disk-shaped carrier of synthetic resin in which coils are accommodated. In order to stimulate a uniform running of the motor the mass of the rotor is increased by manufacturing the carrier from a synthetic resin filled with a filler having a high specific mass.
