NCCER ELECTRICAL MODULE 2 LEVEL 2
EXAM 2026 TEST BANK WITH VERIFIED
CORRECT ANSWERS
⫸ Armature: (Definition) Answer: The rotating windings of a DC motor.
⫸ The ____ is a movable electromagnet located between the poles of
another fixed permanent (field) magnet as shown. Answer: Armature
⫸ A twisting force called ______ must be developed. _____ is produced
by mounting a loop in a fixed magnetic field and as long as the fields of
the magnet and armature interact. Answer: Torque
⫸ Commentator: (Definition) Answer: A device used on electric motors
or generators to maintain a unidirectional current.
⫸ In the neutral plane, no ____ is produced and the rotation of the
armature should stop Answer: Torque
⫸ A _____ is produced by the fields poles, and a loop of wire in the
armature turns and cuts this magnetic field. Answer: Magnetic field
⫸ CEMF Answer: Counter electromotive force (CEMF)
, ⫸ Horsepower: (Definition) Answer: The rated output capacity of the
motor. It is based on breakdown torque, which is the maximum torque a
motor will develop without an abrupt drop in speed.
⫸ Horsepower: (Equation) Answer: Hp= Watts/746
⫸ Types of DC motors Answer: Shunt
Series
Compound
⫸ Types of AC motors Answer: Synchronous and Induction (Single and
Polyphase)
⫸ Periodic duty: (Definition) Answer: Intermittent operation at a
substantially constant load for a short and definitely specified time.
⫸ Revolutions per minute (rpm): (Definition) 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) 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.
