An apparatus and method for estimating the position of a rotor. An apparatus comprises a first rotor having an angular position, a second rotor which interacts with the first rotor in a magnetically geared manner, a sensor for measuring a kinematic property of the second rotor and means for estimating the angular position of the first rotor using a model-based observer, wherein the estimation is based on at least the kinematic property of the second rotor.A method of estimating the angular position of a first rotor comprises measuring a kinematic property of a second rotor, wherein the second rotor interacts with the first rotor in a magnetically geared manner; and estimating the angular position of the first rotor using a model-based observer based on at least the kinematic property of the second rotor. |
