摘要
Common position sensors cannot achieve detection of the rotor position with high precision at high speed, which badly hinders the development of servo control for high-speed motors. In this paper a novel single-pole magnetic encoder has been proposed for precision feedback of rotor position of high speed motors, and a compensation algorithm for feedback lag has been put forward to ensure the control precision. Control experiment has been carried out with a permanent-magnet synchronous motor(PMSM) with 600 W, 4 pairs of poles and the rated rotation speed of 20000 r/min, and confirms the validity of vector control of high speed motor by using the position sensor proposed.
