What are the major parts of a DC motor?

The major parts of a DC motor include the armature, brushes, fields, and frame. The armature is the rotating component of the motor and consists of windings that create a magnetic field when current passes through them. Brushes provide electrical contact between the stationary and rotating parts of the motor, enabling current to flow to the armature windings. The fields are responsible for creating a fixed magnetic field, which interacts with the armature's magnetic field to produce torque and rotation. The frame serves as the physical structure that houses and supports the motor components.

This combination of parts is crucial for the operation of a DC motor, as they work together to convert electrical energy into mechanical energy efficiently. Understanding the function of each component helps in the troubleshooting, maintenance, and optimization of DC motors in various applications.
