Method of placing coils in a basket or distributed
winding
Objectives: At the end of this lesson you shall be able to:
• state the various methods employed to prepare gang or group of coils
• explain the method of placing coils in the single layer basket winding
• explain the method of placing coils in a double layer basket winding.
The procedure outlined below is common for single or three-phase distributed winding. However this type of
basket (distributed) winding is very popular in three phase motors.
The coils can be wound using a single former and then they can be interconnected by coil connections as shown
in Fig 1. Most of the three-phase motors with the exception of very large ones with formed windings, use coils
wound in groups as shown in Fig 2.
