Abstract:
A method of manufacturing an insulating material for use in an electrical generator rotor, the method comprising the steps of:coating a single layer of fabric material with a thermosetting polymer resin and curing the resin to form an insulating substrate layer having a top surface, a bottom surface and a predetermined thickness; adhering a layer of contacting material to the top surface of the insulating substrate layer to form an insulating material top surface having a predetermined coefficient of friction; disposing a first of layer of copper winding material in a channel of the electrical generator rotor; adhering the bottom surface of the insulating substrate layer to the first layer of copper winding material; and disposing a second layer of copper winding material onto the insulating material top surface, the layer of contacting material providing for relative movement between the first and the second layers of copper winding material.
