ABSTRACT:
Attachments are removably coupled to the magnetic core of a rotating electric machine, the magnetic core being shaped to include a plurality of coil-receiving slots that are separated by radial teeth. Each attachment is constructed as a unitary member and includes a base and a stem, the stem being dimensioned for fitted insertion within a recess formed in the distal end of a corresponding tooth. The base includes a convex bottom wall, a flattened top wall and a pair of non-planar sidewalls. The stem is integrally formed on the top wall of the base and includes a front end, a rear end, a flattened top wall and a pair of opposing sidewalls. A longitudinal groove is formed into each of the pair of opposing sidewalls of the stem. An outwardly protruding shoulder designed for engagement by a retention plate is formed into the front and rear ends of the stem.
