Abstract
A stator () for an electrical machine. A core of the stator () is made up of a series of connected segments (), that are rotatable relative to one another during an assembly operation. Each segment () includes a radially outermost base portion () from which a respective integral pole piece () projects substantially inwardly to a pole piece tip. The tip includes a surface () that is arcuate and concentric with an axis of rotation of the machine. Each pole piece () projects in a non-radial direction and such that a semi-closed slot () arranged to locate part of a least one coil () therein is provided between each pair of juxtaposed pole pieces (). A coil () is fittable to a respective one of the pole pieces () during the assembly operation without deformation of the pole piece ().
