Abstract
Described is a direct current motor (1) with permanent magnet stator, having at least four stator poles (5, 6, 7, 8) which are spaced at equal angular intervals about the rotation axis (A) of the rotor (3) and which generate a magnetic field that is asymmetrical about the rotation axis (A) of the rotor (3) and where the rotor winding (4) can be powered partially and selectively at least at two fixed, explementary angular sectors.

A direct current motor with permanent magnet stator, comprising a rotor (3) with a respective winding (4) and at least four stator poles (5, 6, 7, 8) angularly spaced about the rotation axis (A) of the rotor (3);
- the motor (1) being characterized in that the rotor winding (4) can be powered partially and selectively at least at two fixed, explementary angular sectors;
- and in that the stator poles (5, 6, 7, 8) generate a magnetic field that is asymmetrical about the rotation axis (A) of the rotor (3).
