DC motor - Wikipedia

A DC motor is any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current flow in part of the motor.

Construction and Principle of Operation of DC Series Motor

DC series motor works on the direct current converting electrical energy to mechanical energy. It works on the principle of generation of rotational motion when a conductor placed in magnetic field carries current. The interaction of the generated magnetic field and external magnetic field results in the rotational movement. In this motor field winding is placed in series to the armature.
