Indicates the space relationships of windings and changing values of the recurring cycles of AC voltages and currents. The most common power supplies are either single- or three-phase.

The force that causes a current to flow in an electrical circuit. The voltage of a motor is usually determined by the supply to which it is attached. NEMA requires that motor be able to carry its rated horsepower at nameplate voltage plus or minus 1% al

The power required to drive an air moving device. Horsepower required varies with system conditions.
