  • Torqueless relatively moving transformer windings
    Patent number: 4117436
    Abstract: A transformer for coupling between relatively moving elements having a limited degree of motion without inducing torques or forces between the elements as the result of fluxes coupling transformer windings. The transformer includes a primary and secondary coil respectively secured to the relatively moving elements and housed within a core structure of high permeability material which provides a low reluctance flux path for the mutual or coupling flux between the transformer primary and secondary windings and a relatively high reluctance path for leakage flux.
