A bearing assembly includes an annular carrier, an outer ring disposed within the carrier, the outer ring having an outer raceway and a transmitter coil spaced axially from the outer raceway. The transmitter coil is electrically connectable with a battery and is configured to generate an electromagnetic field when current flows through the transmitter coil. An inner ring is disposable about a rotor shaft and has an inner raceway and a receiver coil spaced axially from the inner raceway so as to be located proximal to and inductively coupled with the transmitter coil such that electric current is generated within the receiver coil when current flows through the transmitter coil. The receiver coil is connected to electromagnetic coils of a motor rotor such that electric current flows from receiver coil to the coils. A plurality of rolling elements are disposed between rotatably couple the outer ring with the inner ring.

Self-contained bearing and wireless power transmission device

An imaging system is for recording images of a bearing raceway and includes a platform having a surface sized to receive the bearing ring and an optical imager having a lens. A positioner secures the optical imager or a reflector oriented to reflect light to the optical imager lens and locates the optical imager lens or the reflector axially between first and second axial ends of the raceway and facing generally toward the raceway. A motor rotates the platform or the positioner relative to the other one of the platform and the positioner. A processor operates the optical imager and the motor such that the optical imager takes a series of images about the entire perimeter of the bearing raceway. The processor also indexes each image to a separate one of a plurality of arcuate segments of the raceway and constructs a panoramic image of the raceway.
