A small DC (direct current) motor typically consists of the following main parts:

1. Stator: The stationary part of the motor, which usually consists of a permanent magnet or a set of electromagnets that create a constant magnetic field.

2. Rotor: The rotating part of the motor, which is typically an electromagnet with a coil of wire wrapped around a soft iron core. The rotor is mounted on a shaft that rotates within the stator.

3. Commutator: A cylindrical component made of copper segments insulated from each other. It serves as a mechanical rectifier, periodically reversing the current flow in the rotor coil to keep the motor spinning.

4. Brushes: These are typically made of carbon or a carbon-copper mixture and act as sliding contacts, transferring current from the stationary part of the motor to the rotating commutator.

5. Armature: The rotating assembly consisting of the rotor coil and the commutator.

6. Shaft: The rotating component that extends from the motor housing and provides the rotational output of the motor.

7. Bearings: These support the shaft and allow it to rotate smoothly with minimal friction.

8. End shields or end caps: These enclose the motor and protect the internal components.

9. Windings: The coils of wire wrapped around the stator and rotor that generate and interact with the magnetic fields.

10. Housing or casing: The outer shell that holds all the motor components together and protects them from external elements.

The interaction between the magnetic fields created by the stator and the current-carrying rotor coil generates the torque that causes the rotor to spin, producing the motor's rotational output.
