Abstract
Disclosed is a yoke-less mover of a homopolar linear synchronous machine. The yoke-less mover may include a cold plate having slots. Ferromagnetic cores are fixed to the cold plate. Each of the ferromagnetic cores may protrude through a respective one of the slots, creating gaps between the ferromagnetic cores. Armature windings are fixed to the cold plate. The armature windings may occupy the gaps between the ferromagnetic cores. The ferromagnetic cores of the yoke-less mover have better ferromagnetic utilization and lower weight. It also enables more flexible topologies in the armature windings.
