Abstract
A rolling bearing having a permanently excited first generator () which is arranged in an intermediate space between two bearing rings which are rotatable relative to one another, the first generator having a primary part and a secondary part and generating a first generator voltage when it operates, the secondary part has permanent magnets () which are arranged with alternating polarity on the circumference of one of the bearing rings at least in sections. The rolling bearing includes a second generator (), and the first generator voltage serves for the supply of energy to a sensor arrangement and/or actuator arrangement integrated in the bearing, whereas the second generator outputs a voltage signal for position determination and rotational speed measurement. A method for the energy management of a rolling bearing of this type is also provided.
