  • Patent number: 5446327
    Abstract: A brushless shaft mounted eddy current drive has a coil mounted to bearings by way of a coil mount. The bearings are located on a hub. The coil mount is anchored to a fixed object. The pole pieces are coupled together by a nonmagnetic material to form a cavity that receives the coil. In another embodiment, a brushless drive has a coil rotatably mounted in a cavity within the pole pieces. A rotary inductive coil is mounted to the pole pieces about a stationary inductive coil. Alternating current is provided to the stationary coil to induce current into the rotary coil. In still another embodiment, an alternator is used to induce current into the rotating coil. In a still further embodiment, a brushless drive incorporates a liquid conductive rotatable coupler in the hub.
