Educational worksheet illustrating the components of an electric motor.

Armature: The rotating part of the motor that carries the windings and interacts with the magnetic field to produce torque.
Brushes (1 and 2): Conduct electricity from the stationary part to the rotating commutator, allowing current to flow through the armature windings.
Commutator: A segmented ring attached to the armature shaft that reverses the direction of current in the armature windings as it rotates, maintaining continuous rotation.
Current source: Provides the electrical energy needed to power the motor, typically a battery or power supply.
Field coil: Electromagnets that create the stationary magnetic field which interacts with the armature's magnetic field to produce motion.
Frame: The outer casing that supports and protects the internal components of the motor.
Permanent electromagnet (or stationary magnet): Provides a fixed magnetic field for the armature to interact with; can be a permanent magnet or an electromagnet.
