Abstract

A rotor 10 has projections 11 which confront similar projections 17 on poles 15 of a stator 14; and in any position of the rotor 10, the projections 17 on only one opposed pair of the poles 15 registered with the projections 11. Field windings 16 on the poles 15, and an armature winding 12 on the rotor 10, are energisable to provide either continuous or incremental operation. For incremental operation, winding 12 is not energised but direct current is passed through the windings 16 successively from one pole pair to the next, the speed of rotation of the rotor 10 being determined by the frequency with which the current is switched from one pair of windings to the next. For continuous operation, all of the windings 16 are energised together and a direct current is passed through the armature winding via slip rings (19), the current flow direction through each pair of windings 16 being reversed as a control axis (N) of the armature winding passes the centre line of the respective pole pair. <IMAGE>
