Answer to Question #173132 in Electrical Engineering for george dotse

Question

Draw a well-labelled diagram of the traverse section of a motor field winding showing the interpoles. What is the function of the interpoles?

Answer 1

Functions of Interpoles

1.Are coils that are plaud between the field coils that generate a field that is used to prevent excessive sparking of the brushes.

2.Are auxiliary set of field poles carrying armature current to reduce the field flux caused by armature reaction in a dc motor.

3.Interpoles are used to reduce/neutralize cross magnetizing effect of the armature reaction.
