Abstract
An electric motor for a small-scale electrical appliance, such as a toothbrush or shaver. The electric motor includes at least one oscillatory motor component, a magnet arrangement having at least one permanent magnet, and a coil for generating a magnetic field which, in interaction with the magnet arrangement, generates a force for excitation of an oscillatory linear motion. During the interaction between the magnet arrangement and the magnetic field produced by the coil, a torque for excitation of an oscillatory rotational motion is additionally generated.
