motor basic questions Quiz Practice Quiz | Motor Basics

Q: What is the primary function of an electric motor?

To convert electrical energy into mechanical energy. — Motors use electricity to create motion or work.

Q: Which of the following is NOT a major component of a typical electric motor?

Battery — Batteries supply power; the others are motor parts.

Q: The rotating part of an electric motor is called the:

Rotor — The rotor is the moving part within the motor.

Q: The stationary part of an electric motor is called the:

Stator — The stator provides a stationary magnetic field.

Q: What is the purpose of the commutator in a DC motor?

To reverse the current direction in the rotor windings. — It switches current direction to keep the rotor turning.

Q: What type of energy is primarily used to power an electric motor?

Electrical — Motors convert electrical energy into motion.

Q: Which principle is the fundamental basis of motor operation?

The interaction of magnetic fields — Motors use the interaction of magnetic fields to produce torque.

Q: What is torque in the context of an electric motor?

The turning force that causes the rotor to rotate. — Torque is rotational force.

Q: What is the unit of measurement for motor speed?

Revolutions per minute (RPM) — RPM measures how many times the rotor turns in a minute.
