3ufficiently closely, and may be more quickly drawn. Moreover, 

 the drawing of the connecting lines between the conductors and 

 ends in Fig. 165 is a rather long process, and these lines have no 

 counterpart on the actual armature. 



TWO-CIRCUIT WINDINGS. 



It will have been noticed that in multiple-circuit windings, 

 successive conductors (following the winding connections) lie

under poles of opposite polarity. Thus in the first winding 

 considered (Figs. 151 to 162), the connection was from conductor 

 No. 1 over the back end to No. 50, then over the front end to 

 No. 3. If conductor No. 1 lies under a north pole, conductor 

 No. 50 will lie under a south pole, conductor No. 3 under a north 

 pole, etc. The important requirement is that each successive 

 conductor shall lie under a pole of opposite polarity. This, it is 

 evident, could be accomplished by the arrangement shown in the 

 lower half of Fig. 166, just as well as by the arrangement shown
