초록

A reluctance torque coupler includes a first rotor assembly which provides a magnetic field and a second rotor assembly which rotates relative to the first rotor assembly. The second rotor assembly includes a pair of elongated, arcuate flux poles that are attached to a non-magnetic frame. The flux poles extend towards the first rotor such that they are magnetically coupled to the first rotor. Air gaps between ends define a position of minimum reluctance for the first rotor. When the conductors magnetic axis of the first rotor is aligned with the spaces, ...

청구항

A reluctance torque coupler comprising: magnetic source means for providing magnetic flux having at least one magnetic axis; first rotor means for allowing said at least one magnetic axis to be rotated about a rotational axis; at least two elongated, arcuate, ferromagnetic flux conductors whose opposing ends define narrow spaces, said conductors functioning to conduct at least some of said flux provided by said magnetic source means, said flux conductors having a higher magnetic permeability than said spaces; and second rotor means, to which said flux co...
