ABSTRACT:
A stator assembly has discrete stacks of laminations. A plurality of nonmagnetic containment structures define pockets. The stacks are at least partially received in the pockets and coupled to one another by the containment structure. The containment structures are moveable between a first configuration in which the stacks are separate from one another and a second configuration in which yokes of adjacent stacks are in physical contact with one another. In a method of making a stator assembly, a plurality of stator segments are positioned so each is received in one of a plurality of pockets in a containment structure. Coils are wound around each stator segment while the containment structure prevents the stator segment from having direct physical contact with another stator segment. The containment structure is reconfigured to bring the wound stator segments into contact with one another, thereby forming a closed magnetic circuit.
