Abstract

EN UN VENTILADOR ELECTRICO, QUE ES ACCIONADO POR UN MOTOR DE CORRIENTE ALTERNA, CADA BOBINADO POLAR DEL MOTOR DE CORRIENTE ALTERNA SE HA DIVIDIDO EN AL MENOS DOS BOBINADOS PARCIALES. MEDIANTE UNA CONEXION DIFERENCIADA DE LOS BOBINADOS PARCIALES, EN PARALELO, EN SERIE, EN CONEXIONES EN TRIANGULO Y ESTRELLA SE OBTIENEN EN LOS BOBINADOS PARCIALES DIFERENTES TENSIONES DE RAMAL, LO QUE CONDUCE A DIFERENTES NUMEROS DE REVOLUCIONES DEL VENTILADOR. DEBIDO A QUE TODOS LOS BOBINADOS PARCIALES SE ALIMENTAN SIEMPRE CON TENSIONES DE ALIMENTACION SINUSOIDALES, ES MINIMO EL DESARROLLO DE RUIDOS DEL MOTOR DE CORRIENTE ALTERNA.
