Abstract:
A transverse flux drive having a first component and a second component rotatable with respect to the first component, and first and second transverse flux motors coupled between the first and second components, each motor having a plurality of magnetic pole elements and a plurality of armature elements, wherein:the first component comprises a non-rotating stator and the second component comprises a rotor which rotates relative to the stator, the pole elements of each motor are coupled to rotate with the rotor; at least one of said pole elements and armature elements of one of said motors being axially movable to a position wherein it is magnetic uncoupled from its corresponding armature or pole element; and the pole elements of one motor are coupled to the rotor by members which prevent said pole elements from moving axially with respect to the rotor, and the pole elements of the other motor are coupled to the rotor and are axially movable with respect to the rotor.
