Module description: DC motor is a kind of motor that converts DC electric energy into mechanical
energy. The most common type depends on the force produced by the magnetic field. Almost all
types of DC motors have some internal mechanism, either electromechanical or electronic, to
periodically change the current flow direction of some motors. Most types produce rotational
motion; linear motors produce force and linear motion directly
