Title: An Improved Method of Winding for Electric Machines and Appliances
Inventor: ROUGE RAYMOND
Filed: 1902-04-18
Granted: 1903-02-12
Abstract: 9057. RougÚ, R. April 18. Converting alternating and direct currents; transformers.-A winding for electric machines, e.g., rotary converters, is built up of a number of coils which are all identical with one another and have their conductors arranged in a sinusoidal manner. Fig. 1 shows the principle of the invention. Each of the coils is composed of conductors or groups of conductors, numbered 1 to 6, connected together in series and distributed in such a manner that, if they are assumed to be cut by a plane at right-angles to the axis, the centres of all the sections of conductors or groups of conductors are situated upon a semi-sinusoid S-S, the length of which is equal to the distance from pole to pole of the winding, while the height h is equal to the thickness of the winding. The arrangement and number of the conductors of each coil are such that, if all these conductors are projected upon a line at right-angles to the axis, their projections succeed each other without overlapping and without interruption, as shown on the left-hand side of fig. 1. The successive coils are imbricated with a constant displacement, such that the superposed coils completely fill the spaces reserved for the conductors. In some cases, the coils are composed of groups of conductors having different crosssections in different parts of each coil. It is also possible to subdivide the sinusoids, and to connect the different parts in any desired order of superposition. Figs. 9 and 10 show, by way of example, a coil having six conductors, the guide-curve of which consists of two parts of a sinusoid joined at their summits. Starting from o, the winding of the coil follows the course 4, 3, 5, 2, 6, 1, and terminates at p.
