Vane, piston and gear air motors are widely used in pneumatic transmission. The piston air motor is an air motor that converts the linear motion of several pistons into rotary motion through a crank or swash plate. Piston air motors are mainly used in mining machinery, and can also be used as drive motors for conveyor belts, etc. Only by deeply studying the working principle of the piston air motor, can we use the air motor more skillfully to make life more convenient. Next, we will introduce you to the knowledge of how it works.
