Define Electric Motor :

Electric motor is an elctric rotating machine which convert electrical energy into rotating mecanical energy.

What is Electric Motor ?

An Electric motor is a machine which converts electrical energy  into mechanical energy. Its work is based on the principle that when a current-carrying conductor is placed in a magnetic field, it experiences a mechanical force whose direction is given by Fleming’s Left-hand Rule .

⇒History the First Electric Motor :

• First electric motors were simple electrostatic devices created by the Scottish monk Andrew Gordon in the 1740.

• The theoretical principle behind production of mechanical force by the interactions of an electric current and a magnetic field, Amperes force law, was discovered later by Andre-Marie Ampere in 1820.

• The conversion of electrical energy into mechanical energy by electromagnetic means was demonstrated by the British scientist Michael Faraday in 1821.
