ABSTRACT
A variety of different types of electric motors and other important components make up the power train that provides battery-stored electrical energy that is converted to rotational power that is required to move an electric vehicle-on-wheels . Of course, electric motors are used for other purposes than powering EVs. For instance, at least 60% of the electrical power fed to a typical waterworks and/or wastewater treatment plant is consumed by electric motors. One thing is certain: there is an almost endless variety of tasks that electric motors perform in industry and for personal use. An electric motor is a machine used to change electrical energy to mechanical energy to do the work. (Note that a generator does just the opposite; that is, a generator changes mechanical energy to electrical energy.)
