The inducing or primary coils wound on the core are divided into pairs or units, and they are so connected electrically that while the coils of one pair or set co-operate in fixing the magnetic poles of the core at two given diametrically opposite points, the coils of the other pair or set--assuming, for the sake of illustration, that there are but two--tend to fix the poles at ninety degrees from such points.
With this induction device or converter an alternating current generator is used with coils or sets of coils to correspond with those of the convertor and by means of suitable conductors the corresponding coils of the generator and converter are connected up in independent circuits. It results from this that the different electrical phases in the generator are attended by corresponding magnetic changes in the converter or in other words, that as the generator coils revolve, the points of greatest magnetic intensity in the converter will be progressively shifted or whirled around. This principle of operation may be variously modified and applied to the operation of electro-magnetic motors and the various conditions under which it may be so applied will suggest modifications in the present system. The intention herein, therefore, is merely to describe the best and the most convenient manner for carrying out the invention as applied to a system of electrical distribution. It will be understood that the form of both the generator and converter may be very greatly modified.
