The excitation winding is contained within the stator structure and is located between the main stator windings. Designed to produce a magnetic field powerful enough to fully magnetize the portion of the rotor's magnetic layer that is immediately across the air gap from it, this winding is used to maintain the correct pole geometry in the rotor.

Copper and Motor Efficiency, Motor Copper, Motor Losses

Stator and Rotor Conductors For a motor, either the stator or the rotor can be permanent magnet. When the stator is an electromagnent instead of a permanent magnent, it will be a field coil or field winding, made of either copper or aluminum. For an induction motor, the rotor can be either wound type or squirrel-cage type.
