| Abstract: | Many contactless rotor position sensors can be used in magnetic suspension motors systems. General principles,performances and different situations of the sensors are compared. Dynamic and static characteristics of an eddy-current sensor are studied systemically. Errors and the methods to eliminate them in the rotor position detection system are given. A testing application example of eddy-current sensor in a magnetic suspension motor is provided.The results show that the eddy-current sensor can be the better candidate meeting with the multi-freedom degree complex controls of the magnetic suspension system for its small size,high sensitivity,anti-noise and preferable dynamic performance. |
