ELECTRIC MOTOR FOR A SMALL ELECTRIC APPLIANCE

摘要

The invention relates to an electric motor for a small electric appliance, comprising a rotor and a stator, a coil for the generation of a magnetic field; and a first magnet arrangement having a first permanent magnet which, by interaction with a magnetic field generated using the coil, generates a force for the excitation of a rotary movement of the rotor. In accordance with the invention, a second magnet arrangement is provided which has at least one second permanent magnet which is arranged such that a translatory oscillatory movement of the rotor is effected by the Lorentz force acting in the field of the second permanent magnet on the conductors of the coil through which current flows. The invention furthermore relates to a small appliance having an electric motor in accordance with the invention and to a method for the generation of a translatory oscillatory movement of the rotor of an electric motor.
