Abstract
A motor assembly comprising a mover assembly and a stator. The mover assembly comprising a plurality of mover assembly units, each unit comprising: a non-ferromagnetic core with a profile of an outer surface having at least two flat sections lying on intersecting planes; at least two ferromagnetic laminated structures arranged on the at least two flat sections of the non-ferromagnetic core, each ferromagnetic laminated structure includes a stack of ferromagnetic plates, each plate is covered with a non-conductive coating. Each ferromagnetic laminated structure is arranged on a corresponding flat section of the at least two flat sections of the non-ferromagnetic core such that side of each ferromagnetic plate is adjacent to the non-ferromagnetic core thereby making the ferromagnetic plates of the at least two ferromagnetic laminated structures lie on intersecting planes. The mover assembly unit further comprises windings of wire wrapped around the ferromagnetic laminated structures and the non-ferromagnetic core.
