Abstract: 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.

Abstract: A spooler arranged for leading wire to a rotating spool through a wire tension controller and winding it onto the spool while distributing it in alternating directions along the spool between flanges thereof has means for varying the length of the distribution in either direction, arranged to be so controlled by means responsive to changes in the length of the wire in the wire tension controller in a period adjacent the moment of change to the other distribution direction as at least to reduce wound wire profile deficits or excesses adjacent the spool flanges.

Abstract: An electrical machine comprises a longitudinally movable device and an intermediate rotor. A first arrangement of magnets is disposed on a first surface of the longitudinally movable device, and a second arrangement of magnets is disposed on a first surface of the intermediate rotor. The longitudinally movable device is movable in a first direction. The intermediate rotor's first surface is held adjacent the first surface of the longitudinally movable device such that it cannot move in the first direction. The intermediate rotor is, however, rotatable about an axis and the arrangement of the first and second arrangements of magnets translates movement of the longitudinally movable device into rotation of the intermediate rotor about the axis.

Abstract: 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.
