Which of the following are the major parts of a DC motor?

The major parts of a DC motor include the armature assembly, field assembly, brush assembly, and commutator. Each component plays a crucial role in the function of the motor.

The armature assembly is the rotating part of the motor, where the electromotive force (EMF) is generated when current flows through its windings. The field assembly produces a magnetic field, which interacts with the magnetic field produced by the armature. This interaction is essential for creating the torque that causes the motor to spin.

The brush assembly provides electrical connections to the rotating armature through the commutator. The commutator ensures that the current direction in the armature windings reverses at the right intervals during rotation, allowing for continuous motion in one direction.

Understanding the functions of these components highlights their importance in the operation of a DC motor and confirms that the correct classification of the major parts includes the armature assembly, field assembly, brush assembly, and commutator.
