SISTEMAS DC Motors Catedrático: Ing. Gustavo Mendoza Leal Alumno: Alfredo Valdés Cárdenas Introduction A DC motor is a type of electrical machine that converts direct current into mechanical power by means of a magnetic field. DC motors are widely used in field applications because of their many advantages over AC motors such as speed control‚ high starting torque‚ quick starting‚ stopping‚ reverse and acceleration and free from harmonics found in AC.

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 while
