Type of Course:

The coil is a vital part of any electrical machine; if it breaks the motor will not work. It is the job of the Armature Winder to locate the broken parts, remove them and either replace them with new ones or completely rewind all the coils. They use various kinds of testing instruments to trace burnt out coils.

The armature winding is the main current-carrying winding in which the electromotive force or counter-emf of rotation is induced. The current in thearmature winding is known as the armature current. The location of the winding depends upon the type of machine.
