<p>A magnetic gear arrangement comprises: a first gear system having a plurality of first gear members, each first gear member generating a respective first magnetic field for that gear member; a second gear system having a second gear member generating a second magnetic field; and a coupling device which provides arrangements of interpoles between the first gear system and the second gear system. The first gear members are changeably selectable by the coupling device such that the interpoles couple the first magnetic field of a selected first gear member to the second magnetic field to produce a gear ratio between the first gear system and the second gear system, the gear ratio being changeable by changing the selected first gear member.</p> |
