An electric motor has a stator and a rotor. The stator (1) comprises an annular armature (5) having a plurality of poles (7) evenly spaced about the inner circumferential surface of the armature (5) and directed towards a central longitudinal axis defined by the rotor shaft. A pair of firing/accumulator circuits (14,16) are connected in common and in series with respective sets of coils wound about the stator poles. The circuits are switched into and out of contact with their respective coil sets according to the position of the rotor with respect to the stator via position sensing elements which operate switches in the accumulator circuits. In an alternative embodiment firing and accumulation is effected using commutators and electrolytic capacitors (ECP, ECN). The motor is adapted to retrieve breakdown energy of the magnetic fields to realise a more efficient motor. (FIG1).
