A permanent magnet linear motor (135) including a primary (137) comprising a magnetically permeable core having a first face surface on a first side of the core, a plurality of teeth forming a plurality of slots on the first side, and a plurality of multiphase windings wound to have segments thereof in the slots forming a plurality of magnetic poles at each of the first face surfaces. A permanent magnet pair of opposing polarity is configured to produce magnetic flux and cause the primary (137) to exert a force on the secondary (139a, 139b) when the plurality of multiphase windings are excited by a multiphase source. A passive ferromagnetic secondary (139a, 139b) is adjacent to but spaced from the first face surface, the passive ferromagnetic secondary (139a, 139b) being moveable with respect to the primary (137).
