Motors work through electromagnetism. If you run electricity through a wire, it creates a magnetic field. If you coil the wire around a rod and run electricity through the wire, it creates a magnetic field around the rod. When you surround that rod with other magnets, the rod will rotate as the magnets attract and repel each other.
THE STATOR
Every electric motor has two essential parts: one stationary, and one that rotates. The stationary part is the stator. Though configurations vary, the stator is most often a permanent magnet or row of magnets lining the edge of the motor casing, which is usually a round plastic drum.
THE ROTOR
Inserted into the stator is the rotor, usually consisting of copper wire coiled around an axle. When current is applied to the coil, the resulting magnetic field interacts with that created by the stator, and the axle begins to spin.
THE COMMUTATOR
An electric motor has another important component, the commutator, which sits at one end of the coil. It is a metal ring divided into two halves. It reverses the electrical current in the coil each time the coil rotates half a turn. The commutator periodically reverses the current between the rotor and the external circuit, or the battery. This ensures that the ends of coils do not move in opposite directions, and ensures that the axle spins in one direction.
BRUSHES AND TERMINALS
At one end of the motor are the brushes and the terminals. They are at the opposite end from where the rotor exits the motor casing. The brushes send electrical current to the commutator and are typically made of graphite. The terminals are the locations where the battery attaches to the motor and sends the current to spin the rotor.
