What are two common design types of pneumatic motors?

The correct choice highlights two common design types of pneumatic motors: vane and piston.

Pneumatic motors operate by converting compressed air into mechanical energy, and both vane and piston designs are widely utilized in various applications due to their efficiency and reliability.

Vane motors utilize a rotor that has multiple vanes that extend outward and slide in and out of slots, allowing for smooth rotation. This design is advantageous in applications requiring consistent torque and speed.

Piston motors, on the other hand, use a series of pistons that move back and forth within cylinders as compressed air enters and exits. This design is particularly effective for generating high torque at low speeds.

Each of these types is suited for specific tasks, making them prevalent in industries that rely on pneumatic systems for automation and power.
