WINDINGS FOR ELECTRICAL MACHINES

摘要

A coil for an electrical machine is wound from a foil conductor. The foil is initially wound on a former with the thickness of the foil extending away from the former. The coil is subsequently transferred to a bending tool and the sides of the coil are manipulated so as to turn the coil sides through approximately 90 degrees. After assembly to the stator of the electrical machine, the coil exhibits excellent heat transfer for the losses in the coil, enabling cool running of the winding or increased rating for the machine.

1. A coil for an electrical machine having a stator with salient poles, the coil comprising:
a wound conductor to form the coil having a space for accepting a salient pole of an electrical machine; wherein the conductor has a width and a thickness and an aspect ratio of width to thickness greater than 10; and wherein the width of the conductor extends in a direction away from the space in a portion of the coil.
