摘要: A magnetic gear arrangement, having a first gear member for generating a first magnetic field and a second gear member for generating a second magnetic field. An interpole member is provided between the first and second gear members for coupling the two magnetic fields and controlling the gear ratio between the two gear members. The interpole member includes a unitary body of magnetisable material and associated control wiring, and is arranged such that when current is passed through the wiring, space regions of the unitary body are magnetised by an electrically-induced magnetic field. Discrete interpoles, the number and spacing of which define the gear ratio, are then formed in the unitary body between adjacent magnetised regions.

摘要: A magnetic gear arrangement comprises: (i) a first gear member for generating a first magnetic field, (ii) a second gear member for generating a second magnetic field, and (iii) a coupling device which provides arrangements of interpoles between the first gear member and the second gear member. The interpoles couple the first and second magnetic fields such that different arrangements of interpoles produce different gear ratios between the first and second gear members. The coupling device comprises a plurality of ferromagnetic pole elements which at leastly partly form the interpoles. Each pole element has a Curie temperature whereby the pole element is active below its Curie temperature and inactive above its Curie temperature. The magnetic gear arrangement further comprises a temperature controller for controlling the temperature of at least some of the pole elements such that, under the control of the temperature controller, the temperatures of pole elements can cross their respective Curie temperatures and thereby change from active to inactive or the reverse.

摘要: 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.

摘要: A magnetic gear arrangement is provided comprising a first gear member for generating a first magnetic field and a second gear member for generating a second magnetic field. A coupling element is disposed between the first and second gear members and provides arrangements of interpoles which couple the first and second magnetic fields. The coupling element comprises a plurality of magnetisable lamellae, each interpole in an arrangement of interpoles being formed from a group of neighbouring lamellae. Selected lamellae are deactivatable to provide boundaries between adjacent interpoles. This allows different numbers and arrangements of interpoles to be formed, so as to provide different gear ratios between the first and second gear members.

摘要: A magnetic gear arrangement is provided having a first gear member that generates a first magnetic field and a second gear member that generates a second magnetic field. A plurality of interpoles are disposed between the two gear members for coupling the first and second magnetic fields to control a gear ratio between the gear members. At least one interpole has wiring associated with it that can be activated to alter the magnetic flux at the interpole, so as to vary the coupling between the first and second magnetic fields. The wiring is electrically connected to an electronic filter, which modifies the current passing through the wiring, so as to modify the influence of the wiring on the magnetic flux at the interpole.
