(Electrical engineering: Electrical power, Motor or generator)
A pole piece is a piece of magnetic material that forms an extension of the magnetic circuit inan electric motor, and is used to concentrate the magnetic field where it will bemost effective.
The current in the rotor creates a magnetic flux that reacts with the pole piece to create torque.
When the current of the AC wave form increases from zero toward its positive peak,a magnetic field is created in the pole piece.
