DEFINITION
Classification: 318/496
(under subclass 495) Subject matter in which the armature or primary windings comprises two or more windings or sections thereof, one or more of which are displaced in space relation to one or more others of the windings and which windings or sections thereof are designed and adapted to be connected to a polyphase source of supply (i.e., two or more sources of alternating current having the same frequency and being displaced in time phase relation to each other).
