Abstract:
1. A bearing, comprising: an axis of rotation; a first bearing ring having a body with a magnetically conductive section; a second bearing ring having a body with a magnetically conductive section; a rolling body: a power generation unit which comprises: the second furthest distance is less than the first furthest distance; a closed magnetic circuit running peripherally around the induction coil is closed by the first magnetic pole of the first pole pair via the first claw of the claw ring; the first claw of the claw ring is arranged in a magnetically conductive connection with the magnetically conductive section of the body of the first bearing ring; the magnetic poles of the magnetic pole pairs are arranged in a magnetically conductive connection with the magnetically conductive section of the body of the second bearing ring; and, the magnetic circuit is closed substantially via the magnetically conductive section of the first bearing ring, the magnetically conductive section of the second bearing ring, and the rolling body.
