In this paper. a novel LPMV machine that employs magnet arrays with appropriate magnetization directions has been described. The salient feature of the proposed machine is that both the three-phase armature windings and PMs are integrated in a short mover. while the stator is made of toothed lamination. Thus. the proposed machine topology is particularly suited for long-stroke applications. It has been shown that the proposed machine exhibits high force density with relatively large airgap necessary for the targeted application in urban rail transit systems. It has also been found the thrust force ripple of the proposed machine is quite lower since the detent force and the fluctuating force due to reluctance variation are in opposite phase. The merits and performance of the proposed machine have been validated by the measurements on the prototype machine and drive.
