Totally Enclosed motor enclosure type that restricts the flow air into or
Fan Cooled (TEFC) out the motor, but uses fan blow air over the
motor’s exterior. Some types transistors are used as
electronic switches.

Transistor semiconductor device which usually has three terminals
although the names the terminals are different for different
types transistors.38
Torque turning twisting force. Since torque expressed force
times the length the radius which the force measured,
torque represented compound units such pound-feet
