in kw. ; the multiple path winding which generates one-sixth 

 as much e.m.f. as the wave winding could carry six times 

 as much current, making the output of the two windings 

 the same. 



The six path ring winding shown in Fig. 41 shows how 

 the six paths are formed in a multiple path winding; also

how the voltage of the machine is the same as the voltage 

 generated in one path. 



In a bipolar machine the lap and wave windings are 

 just alike except for the end connections, where the coil 

 connects to the commutator. The difference between 

 the two styles really appears only in a multipolar machine.
