DE 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. Applications of DC motors include
