Abstract:
1. A bearing, comprising: an axis of rotation; a first bearing ring having a body with a section; a second bearing ring located radially inward of the first bearing ring body in a radial direction orthogonal to the axis of rotation; a plurality of rolling bodies; and, a power generation unit, comprising: every rolling body included in the bearing is included in the plurality of rolling bodies; all the rolling bodies in the plurality of rolling bodies are aligned with each other in the circumferential direction; a closed magnetic circuit, which runs peripherally around the magnetic induction coil to the second magnetic pole, is closed by the first magnetic pole via one of the first claws of the first claw ring and via one of the second claws of the second claw ring; the first claw ring and the second claw ring are each arranged in a magnetically conductive connection with the section of the body of the first bearing rings; and, the magnetic circuit is closed substantially via the section of the body of the first bearing ring.
