Abstract
A generator assembly for harvesting energy in a bearing arrangement having a first component and a second component, wherein the first component is configured to rotate in relation to the second component. The generator assembly includes a plurality of coils attached to the first component, wherein the coils are configured to interact with a magnet ring with alternating magnetization directions attached to the second component. In order to achieve an adaptable and flexible design, the coils are placed and oriented such that a winding axis of the coils is oriented in an essentially circumferential direction in relation to a rotation axis of the bearing arrangement.

A generator assembly for harvesting energy in a bearing arrangement having a first component and a second component configured to rotate in relation to the first component, the generator assembly including:
- a plurality of coils attached to the first component,
- wherein the coils are configured to interact with a magnet ring with alternating magnetization directions attached to the second component,
- wherein the coils are placed and oriented such that a winding axis of the coils is oriented in an essentially circumferential direction in relation to a rotation axis of the bearing arrangement.
A bearing assembly including:
- a bearing,
- at least one sensor for determining an operating parameter of the bearing;
- at least one electronic device for at least one of (a) processing signals of the sensor and (b) transmitting signals of the sensor;
- and
- a generator assembly comprising:
- a plurality of coils attached to the first component,
- wherein the coils are configured to interact with a magnet ring with alternating magnetization directions attached to the second component,
- wherein the coils are placed and oriented such that a winding axis of the coils is oriented in an essentially circumferential direction in relation to a rotation axis of the bearing arrangement.
