ABSTRACT:
An improved hybrid variable reluctance linear forcer design of the type known as a Sawyer motor forcer is provided with a 6-phase magnetic design. The 6-phase magnetic design has reduced force ripple compared to existing 2/4-phase and 3-phase designs providing smoother motion with lower velocity ripple. Three identical electromagnets each having four salient toothed poles with each pole being spaced at a unique 30 degree phase increment form a 12-pulse force function equivalent to a 6-phase motor. The electromagnets are provided with split-phase windings, which enable balanced 3-phase amplifiers to drive 6-phase coils.
