Abstract
Abstract In order to reduce the operating noise of a reluctance motor having rotor poles (2.1) which have reduced reluctance and are distributed over the rotor circumference thus forming cut-outs (5) having increased reluctance, the cut-outs (5) are provided, at least on the circumferential side of the rotor, with a filling (2.11; 3.1, 3.2) with a smooth circumferential surface for the purpose of preventing noise being formed by turbulence and with a magnetic permeability for the purpose of preventing noise being formed by magnetostriction and/or moment pulsation, with a rotor which rotates relative to the stator (1) during operation. <IMAGE>
