Design and Thermal Modeling of Modular Hybrid Excited Double-Sided Linear Flux Switching Machine

This paper presents a Hybrid Excited Double-Sided Linear Flux Switching Machine (HEDSLFSM) with crooked tooth modular stator. Generally, the conventional stators are made of full-length iron core, increasing manufacturing costs and losses. Higher losses result in lower efficiency overall performance. A U-shaped stator is used to consumption increase machine’s efficiency. Ferrite magnets replace rare earth magnets, which also reduces machine cost. Two DC excitation windings above below ferrite magnet reduce PM volume. 2D electromagnetic performance analysis done observe key indices. Geometric optimization optimize Split Ratio (S.R), winding slot area (DCw), AC (ACw). Stator Tooth Width (STW), space between modules (S.S.), angle (α) optimized through JMAG in-built Genetic Algorithm (G.A.) optimization. High thrust force density make it good candidate for long-stroke applications like railway transits. The thermal performed by FEA then validated LPMC (Lumped Parametric Magnetic Equivalent Circuit) model. Both analyses compared, an error percentage less than 4% achieved.
