1. A stator assembly, comprising:
- a) a plurality of discrete stator segments each at least partially encased with a phase change material, wherein the phase change material also comprises a bridge between adjacent segments to link adjacent segments into a continuous strip; and
b) the linked stator segments being arranged and secured together to form the stator assembly, wherein the stator segments are held in a toroidal shape by a retaining member which comprises a metal band.

Abstract
A plurality of stator arc segments 20 are linked together by a phase change material 22 enabling simplified winding and higher slot fill. Once wound this continuous structure can be formed into a toroidal core 17 for a stator assembly 40 used to make a motor 100. In a preferred embodiment, a monolithic body 42 of phase change material substantially encapsulates the conductors and holds the stator arc segments 20 in contact with each other in the toroidal core 17. Hard disc drives using the motor 100, and methods of constructing the motor 100 are also disclosed.

14. A combination of stator arc segments and a flexible carrier used to link said stator arc segments during a winding operation comprising:
-
a) a plurality of stator arc segments; and b) a phase change material constituting said flexible carrier adhered to the stator arc segments which links said segments in a uniform and predetermined position with respect to one another;
wherein the flexible carrier links said segments by connecting two mating sections formed in said carrier.
