Abstract:
A two-phase motor formed by a stator part excited by electric coils and by a magnetized rotor, characterized in that the rotor is provided with N pairs of poles magnetized radially in alternate directions, N being equal to 3 or to 5, and in that the stator part is provided with at least two ""W""-shaped circuits, each having an electric coil surrounding a central leg and pole shoes, the ""W"" circuits being disposed such that when one of the central legs is facing a magnetic transition, the other central leg is facing a magnetic pole, the pole shoes of the legs of a ""W"" circuit being spaced angularly by .pi./4 and the pole shoes of the central legs of two ""W"" circuits belonging to different phases being spaced angularly by an angle substantially equal to .pi./2.+-.k. .pi./N, where N is the number of pairs of magnetic poles, in this case 3 or 5, and k is equal to 0, 1 or 2.
