The general equation, then, for multiplex wave windings is w = py + 2m, where m = number of windings, and the general rules governing wave windings of one turn are collected together below. Coil windings are considered on p. 110. Importance of Multiplex Two-circuit Drum Windings.--As the two-circuit simplex winding has only two circuits, the voltage developed is higher than that of the corresponding multiple-circuit case where there are more than two poles. Hence, if the current to be collected is too heavy for a two-circuit winding, it is usual to adopt the multiple-circuit type. Thus the multiplex forms of the two-circuit winding are relatively unimportant, and the multiplex forms of multiple-circuit windings are only necessary for such purposes as plating or for electric furnaces. Rules governing Two-circuit Windings.--1. Two-circuit windings are of necessity " wave" windings, the system of end connections being such as to pass continually in one direction around the armature periphery when the winding is reduced to its simplest form--i.e. with one turn per commutator section. 2. These armatures may be simplex, duplex, triplex, etc., according to the number of parallel paths (through the armature) from brush to brush. 3. A multiplex winding may be singly or multi-re-entrant; this re-entraney depending upon the relationship between the pitch and the number of windings. 4. There must be in all cases an even number of conductors, which must be a multiple of the number of commutator sections (and also, in the case of a slotted armature, of the number of slots). 5. The rules for connection are given by the general formula w = py 2m where w is the number of conductors; p is the number of poles; m is the number of windings required; y is t...
