In the case of a two-pulse brushless d.c. motor narrow auxiliary poles (81-84; 115-122) are provided in the region of the boundaries (44, 45) between neighboring main poles of the rotor, the auxiliary poles being at least in part of polarity opposite to that of the surrounding main poles of the rotor. As a result of this, one obtains an especially favorable functional dependence of the induced voltage upon rotor angular position.
