Abstract

Hybrid excited flux switching linear machines (HEFSLM) are attracting attention in rail transit applications due to their high thrust force density, power density, and efficiency. more importantly, their flux controlling ability gives them an edge over permanent magnet machines, which possess constant flux. This paper investigates a modular mover HEFSLM (MMHEFSLM) with concentrated armature and field windings. The concentrated windings result in thrust force ripples but reduce the copper losses. The modular structure of the mover helps in achieving fault-tolerant ability. The volume of PM is significantly reduced, which is rare-earth material and its price is rising progressively. JMAG in-built genetic optimization is utilized to refine the leading CAD parameters thereby improve performance compared to the initial design. The fault-tolerant ability of the proposed machine is verified by the phase’s inductance calculation. Finally, based on the electromagnetic performance, the proposed MMHEFSLM is compared with conventional design in the literature.
