Abstract:Abstract—The longitudinal end effect of the double-sided permanent magnet linear synchronous motor (DS-PMLSM) causes a large end force. To overcome this drawback, this paper proposes a novel DS-PMLSM structure, in which the upper or lower primary component is shifted by a certain distance. First, the end-force model of the DS-PMLSM is established, based on which, the influences of the staggered structure on the fundamental and higher-order end-force components are analyzed. Following this, the DS-PMLSMs with different slot–pole
combinations are divided into four categories, and the design principles of possible winding arrangements are discussed. Furthermore, the staggered structures are applied to four slot–pole combinations, namely 21-pole/18-slot, 15-pole/18-slot, 20-pole/18-slot, and 16-pole/18-slot. The back electromotive forces (EMFs), detent forces, thrusts and normal forces of the four
combinations are analyzed and compared through the finite element method (FEM).
