Abstract
A stator for an electrical machine includes a back iron including a substantially cylindrical annular structure having an inner surface and an axis. A plurality of supports are fabricated of non-magnetic material, each support extending parallel to the axis of the annular structure along the inner surface of the annular structure, each support including a primary base and at least two primary support members. The primary bases substantially conform to the inner surface of the back iron with the primary support members extending radially inward from the primary base towards the axis of the annular structure. A stator winding is positioned between the at least two primary support members and between the primary base of the support and the axis of the annular structure.
