Publication number: 20150300412Abstract: A compact resolver bearing constructed in a particularly simple manner is provided. The corresponding coils P, S are arranged in the annular chamber formed between the bearing rings, the annular chamber being sealed by two circular ring discs, each of said circular ring discs being non-rotatably mounted on another ring and extending radially in the direction of the other ring while maintaining a slight axial distance A from the respective other circular ring disc. In order to modulate the magnetic flux generated by the toroidal coil P1 in the bearing, the circular ring discs are each provided with a segment made from a magnetically permeable material. The changeable mutual overlapping of the segments during rotation causes the magnetic resistance of the corresponding magnetic circuit M1, M2 to change.Type: ApplicationFiled: September 4, 2013Publication date: October 22, 2015Inventor: Joerg Kegeler
