Abstract
There is provided a method of using an electric machine. To generate torque, electricity is provided to stator coils on a plurality of salient poles of a stator arranged around a rotor having a plurality of salient poles to pull the rotor salient poles in the circumferential direction. To generate electricity, the method comprises rotating the rotor and generating a magnetic field on a magnetizing member. The magnetizing member is arranged coaxially with the rotor and offset from the rotor in the axial direction. The method further comprise conducting the generated magnetic field to the salient poles of the rotating rotor to induce alternating magnetic flux on the stator coils, and recovering electricity generated by the induced alternating magnetic flux from the stator coils. The generated magnetic field does not change its configuration when the rotor rotates except for distances between the closest pairs of rotor salient poles and stator salient poles.
