6. REWINDING AND TESTING OF ELECTRIC MOTORS
6.1 METHOD OF REWINDING
To start the armature winding, the armature is mounted on the winding stand as in Fig. 6.1,
then the shaft, armature core and slots are insulated as per the insulation scheme taken from
the data.

6.2 WINDING METHODS: There are two methods of winding the armature 1) Hand winding
2) Formed coil winding
Hand winding: For hand winding, four numbers of slot feeders are laced in the two designated
slot at a distance from the coil pitch.
The required number of turns are wound into the slots, say slots Nos. 1 and 4 as in Fig. 6.2.
Enough tension is applied on the wire to make a tight winding without breaking the wire.
