Glossary of Motor Terms AC ( Alternating Current ) : The commonly available electric power supplied by an AC generator and is distributed in single or three phase Armature Inductance, Mho forms. AC current changes its direction of the flow Armature inductance in mill-henries (saturated). (cycles). Armature Reaction: Ac Motors: The current that flows in the armature winding of a d-c A motor (see motor definition) operating on a-c current motor tends to produce magnetic flux in addition to that that flows in either direction (AC current) there are two produced by the field current. This effect, which reduces general types: induction, and synchronous. the torque capacity, is called armature reaction and can effect the commutation and the magnitude of the Active Iron: motor’s generated voltage. The amount of steel (iron) in the stator and rotor of a motor. Usually the amount of active iron is increased or Armature Resistance, Ohms: decreased by lengthening or shortening the rotor and Armature resistance is measured in ohms at 25 degree stator (they are generally the same length) . Celsius. (cold) Air Gap: Axial Thrust: The space between the rotating (rotor) and stationary The force or loads that are applied to the motor shaft in stator member in an electric motor. a direction parallel the axis of the shaft. (such as from a
