Abstract

UNA MAQUINA ELECTRICA DE RELUCTANCIA TIENE UN ROTOR 12 Y UN NUCLEO 10 ESTATORICO, Y UN JUEGO DE BOBINAS 18 CIRCUNDANDO LOS POLOS ESTATORICOS PARA ACTIVARLOS. ENTRE LOS POLOS ESTATORICOS HAY ESPACIOS EN LOS QUE SE ENCUENTRAN LONGITUDES ADYACENTES DE LAS BOBINAS CIRCUNDANTES. ENTRE LAS BOBINAS ADYACENTES QUE COMPARTEN UN ESPACIO COMUN, EL NUCLEO ESTATORICO SE FORMA DENTRO DE UNA PROYECCION 22 QUE SE EXTIENDE RADIALMENTE HACIA EL ROTOR. LA PROYECCION AUMENTA EL AREA DE CONTACTO ENTRE LA BOBINA Y EL ESTATOR. ESTO PRODUCE EL EFECTO DE REDUCIR LA RESISTENCIA TERMICA ENTRE LOS DOS. CONSECUENTEMENTE, SE PUEDE AUMENTAR LA CORRIENTE DE LA BOBINA, DANDO UNA POTENCIA MAYOR MAXIMA DEL MOTOR. ADEMAS, SE AUMENTA LA RIGIDEZ TOTAL DEL NUCLEO ESTATORICO POR LA PRESENCIA DE LAS PROYECCIONES.
