Abstract

In this chapter, a new position detection method for tubular permanent magnet linear synchronous motor (TPMLSM) is proposed. Instead of using grating sensors, the linear hall-effect sensors are adopted, which reduce the cost largely. In some special PMLSM, the position of hall-effect sensor is restrained by the size of motors, leading to an extra error. So a predetermined lookup table for error compensation is proposed in this paper. Furthermore, the finite element analysis based on Ansoft also demonstrates the validity and reliability of the position detection and error compensation of the tubular PMLSM based on hall-effect sensors.
