 with the corresponding spiral-coil and lap-coil windings; but they

need to be distinguished from continuous-current wave windings 

 of the closed circuit type, which, as we shall see subsequently, are 

 applicable to alternators.

If the common three-phase winding of Fig. 223 is treated in 

 the same way, we obtain the diagram of which a developed portion 

 is shown in Fig. 269. This is a three-phase, two-slot, wave winding.
