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
Potential energy another electrically charged object nearby. The work "W" required to move "q" from "A" to any point "B" in the electrostatic force field is given by typically given in "J" for Joules. A related quantity called "electric potential" (commonly denoted with a "V" for voltage) is equal to the electric potential energy per unit charge. The energy of a magnetic moment formula_44 in an externally produced magnetic B-field has potential energy The magnetization in a field is where the integral can be over all space or, equivalently, where is nonzero. Magnetic potential energy is the form of energy related not
