What is Airgap density?

The air gap flux density is the major parameter that a motor designer will base a motor design on. This presentation will show that the motor magnetic circuit designs can be modified to allow maximum motor performance with lower energy grade magnetic materials than the present high energy rare earth magnets.

Why do we need air gap in motors?

The air gap of a motor is the gap between the stator teeth or core and the rotor magnets. This gap is a key component in the motor design, and affects the overall strength of the magnetic circuit and motor efficiency.
