Abstract
A variable reluctance electric motor comprises a stator including at least three pairs of pole pieces with windings surrounding at least one of the pole pieces of each pair, and a rotor structure. The rotor structure defines a pair of opposed pole pieces each having circumferentially extending extensions on the opposite sides thereof. The extensions extend at least to the adjacent pair of stator pole pieces when the rotor pole pieces are aligned with stator pole pieces, and be selective energisation of the pairs of stator pole pieces, the rotor can be made to move angularly in either direction.
