Abstract
MOTOR DE POTENCIA FRACCIONARIA CON UNA CARCASA POLAR (10) DE CHAPA CONDUCTORA MAGNETICAMENTE Y UN ANILLO DE REFLUJO (11) DE CHAPA CONDUCTORA MAGNETICAMENTE, QUE CIRCUNDA INTIMAMENTE A LA CARCASA POLAR (10) PARA AUMENTAR LA SECCION TRANSVERSAL DE FLUJO MAGNETICO, EN EL QUE EL ANILLO DE REFLUJO (11), CON EL FIN DE LOGRAR UNA FABRICACION ECONOMICA CON GRAN FLEXIBILIDAD Y SEGURIDAD DE FABRICACION, ESTA CONFIGURADO SOBRESALIENTE UN POCO DE LA CARCASA POLAR (10) EN SUS LADOS FRONTALES (102, 103), Y ESTAN CORTADOS DEL ANILLO DE REFLUJO (11) VARIOS LOBULOS (14, 15) DESPLAZADOS UNOS CON RESPECTO A OTROS EN ANGULO PERIFERICO.FRACTIONAL POWER MOTOR WITH A POLAR HOUSING (10) OF MAGNETICALLY DRIVING SHEET AND A REFLUX RING (11) OF MAGNETICALLY DRIVING SHEET, WHICH CIRCULATES INTIMATELY TO THE POLAR HOUSING (10), TO INCREASE THE CROSS-SECTION OF FLOWS. THE REFLUX RING (11), IN ORDER TO ACHIEVE ECONOMIC MANUFACTURING WITH GREAT FLEXIBILITY AND MANUFACTURING SAFETY, IS SET OUT OF A LITTLE BIT OF THE POLAR HOUSING (10) ON ITS FRONT SIDES (102, 103), AND ARE CUT FROM THE REFLUX RING (11) SEVERAL LOBLES (14, 15) DISPLACED SOME WITH RESPECT TO OTHERS IN PERIPHERAL ANGLE.
