Rotor for an electric machine, retainer for retaining a winding in a slot in a rotor, and method of manufacturing a rotor

摘要

A rotor (1) for an electric machine, the rotor comprising: a rotor body (2) having a plurality of axially extending, circumferentially spaced slots (3) therein; at least one winding conductor (5) disposed in each said slot; and a retainer (7) located in each said slot radially outwardly of the or each said winding conductor for limiting radial outward movement of the or each winding conductor; wherein each retainer has a radially inwardly directed surface (8) configured so as to locate the or each winding conductor in a predetermined position in its respective slot. The invention further resides in a retainer and in a method of manufacturing a rotor. <IMAGE>
