Abstract

A reluctance motor comprises a stator having two salient poles (11, 12) and a rotor (16) also having two poles (26, 27) and being of soft magnetic material. The stator poles (11, 12) support windings (13, 14) which when being supplied with current generate a magnetic field which strives to set the rotor in a stable position of equilibrium in which the rotor and the stator poles coincide. Either or both of the stator poles (11, 12) and/or either or both of the rotor poles (26, 27) are designed so as at high flux density to cause a constriction in a part of the cross section of the flux path in order to displace the position of equilibrium and when the flux density is moderate to distribute the flux generally uniformly over the said cross section. The constriction of the flux is formed by two recesses (17-20) or the like which are symmetrically located in a pair of stator poles and rotor poles (11, 26; 12, 27), one recess (19, 20) or the like being located in the rotor pole (26, 27) at its front or rear edge, as seen in the direction of rotation, while the other recess (17, 18) or the like is located in the stator pole (11, 12) at the opposite edge.
