A plurality of clamping grooves 7 of [ U3] are radially arranged on the impeller rotor 5, and a blade 8 is slidably arranged in each clamping groove 7. During the rotation of the impeller rotor 5, the blades 8 in the working volume area 6 are thrown out of the clamping grooves 7 by centrifugal force generated by the rotation until the ends of the blades 8 contact with the inner wall of the cylinder stator 1.
An air inlet 3 and an air outlet are arranged on the side wall of the cylinder stator 1. Wherein, the gas outlet is provided with two, is main gas vent 4 and backpressure gas vent 10 respectively. The intake port 3, the main exhaust port 4 and the back pressure exhaust port 10 are all in communication with the cylinder chamber 2. Can let in compressed air in to cylinder cavity 2 through air inlet 3, compressed air can spout to blade 8 after getting into cylinder cavity 2 to the part outside blade 8 extends draw-in groove 7, and then produces the moment of torsion, drives impeller rotor 5 rotation, the rotatory mechanical energy of output. Exhaust gas is discharged from the main exhaust port 4, and the residual gas of the back pressure is discharged from the back pressure exhaust port 10. If the air inlet 3 and the back pressure exhaust port 10 are exchanged, that is, if compressed air is introduced into the cylinder chamber 2 from the back pressure exhaust port 10, the rotation direction of the impeller rotor 5 is reversed, and mechanical energy in the opposite direction can be output.
Referring to fig. 3, the intake port 3 and the back pressure exhaust port 10 are symmetrically disposed with respect to the center line of the working volume region 6 as an axis of symmetry. Wherein, the central line of the working volume area 6 is the connecting line of the center O of the cross section circle of the impeller rotor 5 and the center P of the cross section circle of the cylinder chamber 2. And the main exhaust port 4 is located at or near the maximum eccentricity of the cylinder stator 1 and the impeller rotor 5.

The diameter of the second eccentric circle is equal to the diameter of the cross-sectional circle of the cylinder chamber 2. The center of the second eccentric circle is positioned at the lower position of the left side of the center of the cylinder cavity 2, so that the left side part of the second eccentric circle comprises the left side of the center line of the working volume area 6, extends out of the cross-sectional circle of the cylinder cavity 2, and avoids the area where the cross-sectional circle of the impeller rotor 5 is tangent to the cross-sectional circle of the cylinder cavity 2. The left part of the second eccentric circle extends out of the cross section circle of the cylinder chamber 2 to form the cross section shape of the first groove body 9. The first groove body 9 is arranged on the inner wall of the cylinder stator 1, so that the space of the working volume area 6 is increased, the reverse torque is increased, the space for expanding compressed air is increased, the pressure difference between the adjacent blades 8 is increased correspondingly, and the power of the motor is further improved. According to actual test, the power of the motor is improved by more than 5%.
