Abstract
A support and positioning structure for a stator assembly of an inductor type dynamoelectric machine is disclosed. The stator assembly includes a plurality of stationary C-shaped armature elements circumferentially located about a central longitudinal axis and supported by end portions. The C-shaped armature elements include armature windings on a base portion extending parallel to the longitudinal axis and legs extending from each end in a radially inward direction. The support structure includes a nonmagnetic ring shaped member sized to be insertable over the bases of the circumferentially spaced C-shaped armature elements. The bases are in contact with an inner portion of the ring shaped member to thereby position the C-shaped armature elements. The ring shaped member may provide improved cooling effects if made of a heat conductive material and may allow air gap tolerances within the stator assembly to be minimized.
