A rotor sensor target for magnetic bearings comprises a ring-shaped assembly of magnetic material (30) mounted on a generally ring-shaped assembly of non-magnetic material (40, 50, 60), which are coaxially arranged and mounted on a shaft (20) having a longitudinal axis of rotation X'-X. The generally ring-shaped assembly of non-magnetic material (40, 50, 60) comprises at least one ring-shaped slit (61) having the longitudinal axis X'-X and may be made of a cheaper material such as aluminum. The ring-shaped slit (61) provides flexibility which permits operation over a wide range of temperatures without risking of damaging the ring-shaped assembly of magnetic material (30). |
