    Vane Air Motor Design:

    Vane air motor design

    • A slotted rotor rotates eccentrically in the chamber formed by the cylinder and cylinder end plates.
    • Since the rotor of rotary vane air motor is off-center and its diameter smaller than that of the cylinder, a crescent-shaped chamber is created.
    • The rotor slots are provided with vanes that move freely to divide the chamber into separate working chambers of different sizes.
    • As a result of the centrifugal force, which is often reinforced by the compressed air, the vanes are forced against the cylinder wall to seal the individual chambers of vane air motor.
    • The actual efficiency of these seals is a function of what is called "internal leakage".

    Features of Vane Air Motor:

    • With explosion-proof performance because of the characteristics of the working medium of the pneumatic motor air itself and structural design considerations, can not produce sparks in the work, so it is suitable for explosion, high temperature, dusty occasions, and can be used in the air very humid environment, without the danger of leakage.
    • The soft characteristics of the pneumatic motor itself enable it to work at full load for a long time, with small temperature rise and overload protection performance.
    • Vane air motor with high starting torque, can start with load.
    • Easy to press, simple operation, van air motor can achieve stepless speed regulation.
    • Compared with the motor, the power size of pneumatic vane motor is small, light weight. Suitable for installation in a narrow location.

    Vane Air Motor Working Principle:

    Vane air motor working principle

    ATO vane air motors are produced with power ratings up to approximately 7 kW. To understand how a pneumatic vane motor works is the important step.

    The gas with a certain pressure reaches the air distribution plate through the air-controlled reversing valve. At this time, the gas enters the rotary vane air motor in two ways: the pressure gas enters the brake chamber and pushes it away brake piston; or the pressure gas enters the motor chamber from the motor air inlet. The pressurized gas generates pressure on the blades and overcomes a certain friction force to push the high torque air motor rotor to rotate. When the blades leave the air inlet 1 behind the chamber, the chamber is at a critical position A. When the front vane of this chamber reaches the main exhaust port, the adiabatic expansion of the chamber is over and it is at the critical position B.

    When the rear vane of this chamber leaves the main exhaust port, enters the critical position C. Chamber undergoes adiabatic compression stage. When the rear vane of the chamber leaves the auxiliary exhaust port, the auxiliary exhaust of this chamber ends and the next cycle of air motor is entered. In this way, the vane type air motor can continuously rotate and output the speed and torque outward.
