When DC energy is distributed by the rotor, it creates a temporary electromagnetic area that interacts with the everlasting magnetic subject of the stator. This creates the torque needed to provide mechanical energy. Inside the tip cap, the motor's brushes switch energy from the battery to the commutator as the motor spins.

The contacts of the commutator are connected to the axle of the electromagnet, in order that they spin with the magnet.
