“How can we use electric energy to create mechanical motion? ”
Given that energy is a conserved quantity, isn’t logical that energy in one form could be transformed into energy of another form? And since two of the most used forms of energy for human civilization is electrical and mechanical energy, wouldn’t it be useful if we can convert from one to another? This is the basis behind an Electric motor. Principally, an electric motor performs one simple function, it uses electrical energy to create mechanical motion. Because they perform such a useful function, electric motors are one of the most prolific inventions of the human race. In fact, they are the most used electrical machines on the planet! Motors can be found as components in a wide range of machines, varying from regenerative braking systems to electric fans to rail transportation. Because of this, there are many types of electric motors, ranging in all types of technology.
