WebNov 8, 2024 · Air-gap eccentricity is made up of two types of conditions, referred to as static and dynamic. Static eccentricity is where the air gap is constant to one side of the stator, while dynamic is where the air gap rotates with the running speed of the rotor. WebAug 24, 2024 · Because there is a tiny gap between the outer surface of the rotor and the inner diameter of the stator, these motors are known as a radial gap or radial flux machines, and they may generate a lot of power because they can run at high speeds. Axial flux motor is considered superior to a radial flux motor. lieutenant governor of delaware
