A fault-tolerant reluctance motor has a multiphase stator winding. The stator (2) has a different number of poles from the rotor (5). The lead angle and the pole angle ((beta)s, (beta)r) embraced by each stator and rotor pole (3, 5) is at least the same as twice the step angle (a): (epsilon)=360 /(q.Nr), where (q) is the number of phases and (Nr), is the number of rotor poles. In particular, the stator has ten poles, the rotor has six poles and the stator winding has five phases. Such a reluctance motor starts up from any motor position in one or other direction of rotation, even when one of the phase windings (6, 7) is completely or partially ineffective owing to a fault. |
