The electric machine comprises a rotor and stator, the rotor and stator having generally equal axial lengths. The stator has at least one primary and at least one control winding disposed around the stator. The electric machine comprises a stator extension of a magnetic material. The stator extension is disposed coaxially with the stator and has only the at least one control winding wrapped therearound. The stator extension extends axially adjacent the stator beyond an axial terminus of the rotor and defines a magnetic circuit around the at least one control winding. The stator extension is configured such that in use, the magnetic circuit remains unsaturated thereby increasing inductance of at least one control winding in an electric alternator/motor.
