 copper conductor slipped into place from the end of the armature.

In such cases as this it is more usual to carry out the winding 

 as a " bar winding," where the conductors or bars are slipped into 

 the slots from the end, and then connected up into coils by means

of separate V-end connectors all of the same size and shape. 

 Such a bar winding is shown in Fig. 265. This having three 

 slots per pole per phase, the diagram of Fig. 264 applies also in 

 this case. It will be seen that the appearance of the end con- 

 nectors in Fig. 265 is exactly the same as in Fig. 264.
