Segmented Stator with Improved Handling and Winding Characteristics
First Claim
1. A stator assembly comprising:
- a plurality of discrete stacks of laminations, each of the stacks having a yoke and a tooth extending away from the yoke; and
a plurality of nonmagnetic containment structures defining pockets, the stacks being at least partially received in the pockets, the containment structures coupling the stacks to one another, the containment structures being moveable between a first configuration in which the stacks are separate from one another and a second configuration in which the yokes of adjacent stacks are in physical contact with one another to form a magnetic circuit.

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.

9. A method of making a stator assembly, the method comprising:
-
positioning a plurality of stator segments so each stator segment is received in one of a plurality of pockets in a containment structure; winding coils around each of the stator segments while the containment structure prevents the respective stator segment from having direct physical contact with another stator segment; and reconfiguring the containment structure to bring the wound stator segments into contact with one another, thereby forming a closed magnetic circuit. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method of making a stator assembly comprising a plurality of stator segments and windings coiled around the stator segments, the method comprising:
-
sandwiching a plurality of stator segments between first and second containment structures comprising a series of pockets connected by flexible hinges so each stator segment is received in a pocket of the first containment structure and received in a pocket of the second containment structure; winding coils around the stator segments; and reconfiguring the containment structures to bring the wound stator segments into contact with one another, thereby forming a closed magnetic circuit. - View Dependent Claims (17, 18, 19, 20, 21)
