摘要：Wound field flux-switching linear (WFFSL) motor has the advantages of high thrust force, small force ripple, no rare-earth magnet, wide operation range and low cost secondary. Hence, the WFFSL motor is ideal for rail transit and vertical hoist system which needs a long stator and a wide speed range. However, its field windings and armature windings are overlapping, which increases the end-winding length and copper loss. In order to further improve the performance of the motor, a new 12/7-pole double-sided WFFSL motor with nonoverlapping windings is proposed and investigated in this paper. The new topology and the operation principle of the proposed WFFSL motor are presented first. Second, the design rules, specification and the parameters of the proposed structure are listed. Then, the two motors are analyzed by using a finite element analysis (FEA) method. Finally, the electromagnetic performance of the double-sided motor and the single-sided motor have been compared and summarized. The results show that the new proposed motor has some merits such as larger thrust force density, smaller maximum normal force, less copper usage, higher efficiency and better heat dissipation. © 2019 IEEE.
