本文对多层线圈无铁心直线电机的直接和间接液体冷却拓扑进行了比较。电磁力的产生是通过3-D磁标量位建模，而热建模是通过3-D有限元和体积法。每种拓扑结构的功耗和力密度进行了研究，为不同的极距和线圈配置。随后，本地化和比较的磁应力和热应力进行两种拓扑结构。此外，几何形状的变化进行了研究，以减轻机械应力。
This paper conducts a comparison between direct and indirectly liquid-cooled topologies for coreless linear motors with multiple coil layers. The electromagnetic force production is obtained by 3-D magnetic scalar potential modeling whereas thermal modeling is performed by 3-D finite element and volume methods. The power dissipation and force density of each topology is investigated for different pole pitches and coil configurations. Subsequently, localization and comparison of the magnetic and thermal stresses is performed for both topologies. Furthermore, variations in the geometry are investigated to mitigate mechanical stresses.
