摘要： 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.

摘要： An electric motor (10) comprises a stator (20) having a primary winding and a rotor (130a,b) arranged to rotate in the stator (20). The rotor comprises a shaft (160), a first magnetic rotor component (140) and a second magnetic rotor component (150), each magnetic rotor component (140,150) having a magnetic pole of a first polarity (43,43',53,53') and a magnetic pole of a second polarity (47,47',57,57'). At least one of the first and second rotor components (140,150) further comprises a structure (35) for carrying induced eddy currents. The second magnetic rotor component (150) is rotatable with respect to the first magnetic rotor component (140) around the shaft (160) from a low-flux orientation to a high-flux orientation. The motor (10) is arranged such that the second magnetic rotor component (150) is in the low-flux orientation when the rotor (130a,b) is at rest and is in the high-flux orientation when the rotor (130a,b) is rotating at an operating speed.

摘要： A magnetic drive has a prime mover, having a first magnet array on a first surface thereof, and a rotor, having a second magnet array on an outer surface thereof. The outer surface of the rotor is located adjacent to the first surface of the prime mover such that movement of the prime mover causes rotation of the rotor about an axis of rotation. A support member has a shaft for defining the axis of rotation of the rotor, and having a third magnet array, and the third magnet array cooperates with a fourth magnet array on the rotor to form a magnetic bearing to resist forces on the rotor acting along the axis of rotation thereof.
