Currently available air motors have many advantages over electric motors. They are more compact, lighter-weight, instantly reversible without sparking, create no heat buildup, are undamaged by stalling or overloading, and supply extremely broad torque and speed range. Generally available commercial air motors, however, have only 5% to 20% of ideal efficiency. The Harmonic Air Motor developed at Lawrence Livermore National Laboratory has all these advantages of air motors, but also offers a proven efficiency more than 60% of ideal, higher low-end torque than available commercial air motors, and can be manufactured at lower cost.
