슬롯리스 리니어 동기모터의 구동특성 개선

Abstract

Attends home automate of recent years, improved performance of linear motor is more required. Control is excellent among linear motors, and the permanent magnet linear synchronous motor (LSM) of high efficiency drive is being applied as operating source. The purpose of this study, that basis primary method as structure of LSM most satisfiable and value relevance of the slotless LSM that thrust force variation does not proceed by the cogging force. Also, the characteristics is obtained by experimental equipment and the aim was to apply. Valuation basis is the acceleration 0.5[m/s²], the maximum speed 0.1[m/s] and the aim was that improve of following of real speed for command speed. It is concluded through experiment when PD control start vibration of real speed for command speed is curbed within ±5[%]. As a result, proved it about usability of the PD control by position feedback through a position following accuracy of the slotless LSM, vibration suppression of a real speed regarding a command speed.
