Abstract

A multi-pole generator rotor and a method of making the same are disclosed. A multi-pole generator rotor includes a rotor body having a central portion with a generally cylindrical outer surface. The outer surface includes three pairs of diametrically opposed slots extending along a length of the central portion, with each of the slots being sized to receive therein a plurality of wires. Each of the slots further includes a pair of opposed retaining flanges. A plurality of retaining members are sized for insertion into a corresponding one of the slots. Each retaining member engages a pair of the retaining flanges from its corresponding slot. The retaining members thereby retaining the wires disposed in each slot against radially outward displacement. A method of forming a multi-pole generator rotor includes the steps of providing the above rotor body, winding first, second and third wire coils by repeatedly winding a wire through a first, second, and third set of opposing slot pairs, and inserting a retaining member longitudinally into each of the slots.
