Abstract

An electrical machine, comprises a first rotor, rotatable about, or movable along, a first axis, and having a first arrangement of ferromagnetic salient poles on a first surface thereof; and a second rotor, held with a first surface thereof adjacent the first surface of the first rotor and such that it is rotatable about a second axis, and having a second arrangement of magnets on the first surface thereof. The first and second arrangements of ferromagnetic salient poles and magnets are such that rotation of the first rotor about the first axis, or movement of the first rotor along the first axis, causes rotation of the second rotor about the second axis.
