Torque A turning or twisting force. Since torque is expressed as a force
times the length of the radius at which the force is measured,
torque is represented in compound units such as pound-feet
(lb.-ft.)

Totally Enclosed A motor enclosure type that restricts the flow of air into or
Fan Cooled (TEFC)
out of the motor, but uses a fan to blow air over the
motor’s exterior.
Totally Enclosed A motor enclosure type that restricts the flow of air into or out
Non-ventilated (TENV) of the motor. Because there are no ventilating openings, all
heat generated by the motor must be dissipated by conduction
through the enclosure.
Transformer Coils of wire wound on a common frame that allow electrical
energy to be transferred from one circuit to another.
Transformers used in low frequency applications are commonly
wound around an iron core to improve energy transfer.
Transistor A semiconductor device which usually has three terminals
although the names of the terminals are different for different
types of transistors. Some types of transistors are used as
electronic switches.
