What  is Construction of DC Motor?

DC Motor Definition

A DC motor is defined as a device that converts direct current electrical energy into mechanical energy.

A DC motor is constructed with:

• A Stator

• A Rotor

• A Yoke

• Poles

• Field windings

• Armature windings

• Commutator

• Brushes

Stator and Rotor

The stator is the stationary part with field windings, and the rotor is the rotating part causing mechanical motion.

Field Winding in DC Motor

Field winding, made of copper wire, generates a magnetic field for rotor operation by creating electromagnets with opposite polarities.

Commutator Function

The commutator is a cylindrical structure that relays current from the power supply to the armature winding.

Brushes and Their Role

Brushes made of carbon or graphite transfer current from the static circuit to the rotating commutator and armature.
