ABSTRACT:
A method of making a motor includes placing radially deformable support cuffs around the protruding winding portion of the stator windings, inserting a core therethrough, placing the assembly in a hollow mould and closing the mould to press the cuffs radially inwardly against the windings, filling the remaining voids in the mould with curable casting material, and curing the material. The resulting unit is removed and the rotor and bearings are inserted. Embodiments of support cuffs are disclosed.
