Horsepower: (Definition) - CORRECT ANSWER The rated output capacity of the

Horsepower: (Equation) - CORRECT ANSWER Hp= Watts/746

Types of DC motors - CORRECT ANSWER Shunt

Series

Compound

Types of AC motors - CORRECT ANSWER Synchronous and Induction (Single and

Periodic duty: (Definition) - CORRECT ANSWER Intermittent operation at a

substantially constant load for a short and definitely specified time.

Revolutions per minute (rpm): (Definition) - CORRECT ANSWER The approximate

full-load speed at the rated power line frequency. The speed of a motor is determined by

the number of poles in the winding.

Rotation: (Definition) - CORRECT ANSWER For single-phase motors, the standard

rotation, unless otherwise noted, is counterclockwise facing the lead or opposite shaft

end. All motors can be reconnected at the terminal board for opposite rotation unless

other wise indicated.
