The invention relates to a rolling element bearing (01) comprising a first bearing ring (02), a second bearing ring (03), and a Lundell alternator (04) that is arranged between said two bearing rings (02, 03). The Lundell alternator (04) comprises a sequence of magnetic poles (05) running along the first bearing ring (02), a sequence of magnetically-conductive claws (12, 13) arranged along the circumference of the second bearing ring (03), and a coil (15). Together the claws (12, 13) and the poles (05) form magnetic rings that surround said coil (15). It is essential to the invention that the magnetically-conductive claws (12, 13) are only arranged along some sections of the circumference of said second bearing ring (03). The coil (15) is arranged in the region of said magnetically-conductive claws (12, 13). The invention also relates to a Lundell alternator for installing in a rolling element bearing. |
