Abstract: Contraposing the constant lowspeed longdistance transport system , studied the lowspeed permanent magnet linear synchronous motor with segmented design. Did some optimization designed on the single section of lowspeed permanent magnet linear motor at first , and then designed how to achieve the best fit among plural segments. With simply introducing the optimal design of single motor, this article introduced more paragraphs motor mainly, introduced the sectional principle , the sectional criterion and how to do sectional optimal design at the same time. The best match between active cell and stator is realized, and the optimal result is obtained according to the artificial figure.
