Abstract

UNA MAQUINA ELECTRICA CON UN DISPOSITIVO ROTOR (1) DE EXCITACION EXTERNA PARA GENERAR CAMPOS MAGNETICOS SUCESIVOS EN EL SENTIDO DE MOVIMIENTO DEL ROTOR (3), EQUIVALENTES A PERIODOS MAGNETICOS ENTEROS, Y CON POLOS DEL ESTATOR (5) DISPUESTOS SUCESIVAMENTE A LO LARGO DEL DISPOSITIVO ROTOR, SE CARACTERIZA POR CORRESPONDER A UN PERIODO MAGNETICO UN NUMERO DE POLOS DEL ESTATOR DIFERENTE DE UN NUMERO ENTERO. UN DESFASE VARIABLE DERIVADO DE LA DIFERENCIA ENTRE LOS PERIODOS DEL CAMPO MAGNETICO Y LOS POLOS DEL ESTATOR SE COMPENSA AL MENOS PARCIALMENTE MEDIANTE UNA ALIMENTACION DEBIDAMENTE DESFASADA DE LAS BOBINAS DE LOS POLOS DEL ESTATOR. PARA ESTA ALIMENTACION DESFASADA SE HAN PREVISTO CIRCUITOS QUE GENERAN OTRAS FASES DE TENSION DE ALIMENTACION A PARTIR DE UNA TENSION DE ALIMENTACION MULTIFASICA. LOS CIRCUITOS ESTAN FORMADOS MEDIANTE LA CONEXION ADECUADA DE BOBINAS POLARES DEL ESTATOR, POR EJEMPLO SE HAN PREVISTO CIRCUITOS QUE INCLUYEN CONEXIONES EN ESTRELLA Y/O TRIANGULO PARA GENERAR FASES ADICIONALES A PARTIR DE UNA TENSION DE ALIMENTACION TRIFASICA.
