Abstract
A reluctance motor electric machine including a number of stator pole teeth and a number of rotor pole teeth selected so that with a minimal reluctance, due to the rotational alignment of the rotor in relation to the stator, three air gaps that can be flowed through are produced between three pairs of stator pole teeth and rotor pole teeth. This results in the fact that now three regions of the yoke body are elastically pulled in the direction of the rotor rotational axis and consequently, the elastically deformed zones of the yoke body only extend over essentially and therefore act in a more rigid fashion. This results in the advantage that with the same excitation frequency, the deformations take place with small amplitudes and therefore with less generation of noise.
