The figure shows a typical pneumatic motor torque and power curve at two different air pressures. The speed, torque and power of the motor decrease as the air pressure decreases. | The figure shows the torque and speed curves of the pneumatic motor under two different air pressures. The speed and torque of the motor decrease as the air pressure decreases. The torque decreases significantly, while the motor speed decreases slightly as the pressure decreases. |
