The Electric Motor has been around for at least 150 years and was the backbone of the Second Industrial Revolution in America. At that time the Electric Motor began to replace the steam-powered machines as the main source of power in industry. Over the years, many people have made great improvements in the design and manufacture of Electric Motors, however, nobody has yet changed the Laws of Physics that cause an Electric Motor to operate.
Working principle of a DC motor
An electric motor is an electrical machine which converts electrical energy into mechanical energy. The basic working principle of a DC motor is: “whenever a current carrying conductor is placed in a magnetic field, it experiences a mechanical force”.
