A novel hybrid permanent linear synchronous motor, which adopts permanent poles and current-excitation poles alternative distribution structure,is introduced in this paper.

The thrust and levitation force in linear synchronous motor with hybrid magnet were analyzed.

A real-time data acquisition of vertical transportation system driven by permanent magnet linear synchronous motor(PMLSM) based on DSP is put forward,and the structure of system hardware and the design of software is described.

The theory of permanent magnet linear synchronous motor(PMLSM)doesn t consummate,the whole math model of the transportation system changes a lot under the primary partition model,and the fringe effects is very fierce,so the servo-system of the PMLSM vertical movement can t be designed according to its math model or by using simple controller.

A new variable parameter mathematic model of multi-segmental primary permanent magnet linear synchronous motor(PMLSM) for vertical movement was obtained in a-b-c frame.
