Abstract
A linear electrodynamic machine (10) includes mover (12) and stator assemblies (14). The stator assembly (14) includes an inner stator having laminations (30-45) and an outer stator having laminations (60-75) for defining a closed loop magnetic flux path. A magnet (95) mounted on an outside portion of the stator assembly (14) produces a constant flux extending through the flux path. The inner and outer stators form at least one pair of aligned spaced apart magnetic poles (50, 80) forming a gap. A group of slugs (24) mounted on the mover assembly (12) moves into and out of the gap to interact electrodynamically with the magnetic flux within the gap. A linear electrodynamic machine (10) includes a stator assembly (14) having at least one pair of elongated stator poles (50, 80) defining a flux gap and having magnets (283A-288A) disposed thereon to interact electrodynamically with a group of slugs (24, 26) mounted on a mover assembly (12) for moving into and out of the gap. Elongated coils (50-53) are disposed on the stator poles (30-33) and are separately wound and then slipped onto their respective poles.
