The rotor with rotating blades is eccentrically installed in the stator cylinder. When the rotor rotates at high speed, the four radial sliding blades in the rotor slot divide the pump chamber into four working rooms. Due to the centrifugal force, the rotating blades are close to the cylinder wall, separating the stator inlet and outlet. Rotor (rotating) is the antonym of stator (stationary). These terms are not specific to aerodynamics, in a electric motor there is usually a stator and a rotor as well.
