A DC motor primarily consists of four key parts:
1. **Stator**: The stationary part that creates a magnetic field, typically made of permanent magnets or electromagnets.
2. **Rotor (Armature)**: The rotating component that houses the windings and conducts current, generating torque.
3. **Commutator**: A mechanical switch that reverses the current direction in the rotor windings, ensuring continuous rotation.
4. **Brushes**: Conductive materials, usually carbon, that maintain electrical contact with the commutator, allowing current to flow to the rotor.
These components work together to convert electrical energy into mechanical energy.

A direct current (DC) motor consists of several key components that work together to convert electrical energy into mechanical motion. Four essential parts of a DC motor are:
1. **Stator**: The stationary part of the motor, which provides the magnetic field. It can be either a permanent magnet or an electromagnet, depending on the type of DC motor.
2. **Rotor (or Armature)**: The rotating part of the motor that is located inside the stator. It consists of a core and windings (coils of wire). The rotor generates torque as it interacts with the magnetic field produced by the stator.
3. **Commutator**: A mechanical switch that reverses the direction of current in the rotor windings as it spins. This ensures that the torque produced by the motor remains in the same direction, allowing continuous rotation of the rotor.
4. **Brushes**: These are conductive materials (usually made from carbon) that maintain electrical contact between the rotating commutator and the external circuit. They provide the necessary current to the rotor windings.
These components work together to produce rotational motion, which can be used to drive various mechanical systems.
