  "textContent": "A bearing assembly includes an outer ring connectable with a housing, 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 disposeable 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.",
