Abstract
An electric motor comprises a stator () having an air-gap which extends around an axis and in which a rotating magnetic field is generated, and a rotor () comprising a shaft () which is rotatably held by a bearing () and a permanent magnet () which is held in said air-gap and is driven to rotate around said axis by said rotating magnetic field. The stator () is adapted to generate, in addition to said rotating magnetic field, a stationary magnetic field which is rotationally asymmetric with respect to said axis.
