1 ELECTRIC MOTORS I. Introduction Electric motors are considered to be important mechanical devices. They usually convert the electrical energy coming from the mechanical device into its kinetic energy to make it work (Petingco and Resurreccion‚ 2011). In this exercise‚ the students were tasked to use an example of an electric motor‚ identify its parts‚ and make it work. All electrical motors are equipped with stator and rotor. Stator is known as the stationary part of an electric motor

is to use the electric motor instead of gasoline one. An electric car is a car that powered by an electric motor rather than a regular gasoline engine. There are several major differences between gasoline and electric cars. First of all‚ “the electric motor will replace the gasoline engine” (“How Electric”‚ 2004). Secondly‚ “the electric motor is powered by a controller” (“How Electric”‚ 2004). Thirdly‚ “the controller gets power from the rechargeable batteries” (“How Electric”‚ 2004). In
