摘要：

In this paper, a segmented-stator linear vernier permanent magnet machine (LVPMM) is proposed for syringe pump systems. The proposed machine adopts segmented-stator linear vernier machine configuration. The mover is sandwiched between the segmented stators. By using the sinusoidal shaped magnets, the harmonics of the back electromotive force is reduced. By selecting an appropriate slot-pole combination and fine tuning the relative position of the two stators, the cogging force due to the slot-pole interaction is mitigated. In addition, by optimizing the stator length, the cogging force due to the end effect is suppressed. With these design techniques, the thrust ripple for the proposed machine can be suppressed. By using the finite element method, the analysis confirms the validity of the design and optimization approach.
