Fractional Horsepower Motor Terms

Actuator – A device that creates mechanical motion by converting various forms of energy to rotating or linear mechanical energy. (http://www.linear-actuators.net)
 
Coil (Stator or Armature) – Electrical conductors in the core slot, insulated from the iron core. They produce and transmit the magnetic field as current passes through.  
 
Commutator – A mounted cylindrical device, to which the motor brushes are attached, on the armature shaft made of copper segments set around the shaft.
 
Constant H.P. – Name used for motors with variables speeds whose loads need the same amount of horsepower despite their speed.
 
Core – The segment of the stator and rotor, usually iron; made up of cylindrical laminated electric steel.
 
Cycles per Second (HERTZ) – A complete reverse flow of alternating current during a rate of time.
 
Duty Cycle – The comparison of operating and rest times due to normal operating temperature.

Efficiency – The ratio of electrical input to mechanical output. It measures the motor's effectiveness when converting electrical energy into mechanical energy.  
 
Enclosures – Either open or closed, the frame or housing of the motor.
 
Endshield – The part of the motor housing that supports the bearing and acts as a protective guard to the electrical and rotating parts inside the motor. An endshield is often referred to as an "end bracket" or "end bell."
 
Horsepower (HP) – Work done per unit of time: 1 horsepower equals 33,000 foot-pounds of work per minute or approximately 746 watts. Motors for pumps are an example of a motor that is rated in horsepower.
 
Jackscrew – A device used for the positioning of a motor. These are adjustable screws fitted on the base or motor frame.
 
Load – The burden of the motor by its application. The required power to overcome the resistance of the machine it powers.
 
Motor – A device that turns a shaft by taking electrical energy and converting it into mechanical energy.
 
Rotor – Made of stacked laminations, the rotating component of an induction motor.
 
Shaft – The rotating part of the motor that protrudes past the bearings for attachment to the driven equipment.
 
Skew – The laminations arranged on a rotor or armature. These help abolish low-speed cogging effects in an armature and reduce induced vibration in a rotor.
 
Stator – In an AC induction motor, it is made of laminations with a large hole in the center for the rotor to turn and slots in the stator for the windings to be inserted.
 
Thermocouple – A device to detect temperature that contains two dissimilar metals which generate voltage as a function of temperature. (http://www.thermocouple-assemblies.com)

Torque – Force for turning, provided by a motor or gearmotor shaft, often expressed in pounds.
