write working of dc motir not it's principle or construction​

◆ Axle, Rotor, Commutator, Field magnets, and Brushes. The basic component of a DC motor is a current carrying armature which is connected to the supply end through the commutator segment and brushes. The armature is placed between two permanent magnets which produce a magnetic field. ... This is how a DC motor Works.

◆A motor is an electrical machine which converts electrical energy into mechanical energy. The principle of working of a DC motor is that "whenever a current carrying conductor is placed in a magnetic field, it experiences a mechanical force".


◆DC series motor starter. Construction of DC series motor starters is very basic as shown in the figure. The start arm is simply moved towards right to start the motor. Thus, maximum resistance is connected in series with the armature during starting and then gradually decreased as the start arm moves towards right.
