Pneumatic motor Pneumatic motor A pneumatic motor (air motor) or compressed air engine is a type of motor which does mechanical work by expanding compressed air. Pneumatic motors generally convert the compressed air energy to mechanical work through either linear or rotary motion. Linear motion can come from either a diaphragm or piston actuator, while rotary motion is supplied by either a vane type air motor, piston air motor, air turbine or gear type motor. Pneumatic motors have existed in many forms over the past two centuries, ranging in size from hand-held motors to engines of up to several hundred horsepower. Some
Binding energy Binding energy Binding energy (also called separation energy) is the "minimum" energy required to disassemble a system of particles into separate parts. This energy is equal to the mass defect - the amount of energy, or mass, that is released when a bound system (which typically has a lower potential energy than the sum of its constituent parts) is created, and is what keeps the system together. If the energy supplied is more than the binding energy, then the disassembled constituents possess non-zero kinetic energy. In general, binding energy represents the mechanical work that must be done against the forces
