Abstract
A self-starting brushless electric motor having a first motor part (stator) (,) with poles arranged in a row, the poles constituting ferromagnetic poles (,S) or permanent-magnet poles (,A), a second motor part (rotor) (,) with poles arranged in a row, the poles having ferromagnetic poles (,A) or permanent-magnet poles and being arranged opposite the row of poles on the first motor part (,), wherein the motor part with salient ferromagnetic poles or, if both motor parts have salient ferromagnetic poles, at least one of the motor parts has a permanent-magnet pole, and also a magnetizing winding on the first motor part. The system of poles formed by the pole rows is magnetically asymmetrical in the direction in which the motor parts (,) are movable in relation to each other.
