Abstract

MAQUINA ELECTRICA GIRATORIA UNIDIRECCIONAL DE IMAN PERMANENTE Y CORRIENTE DIRECTA FORMADA POR UN ESTATOR; UN ROTOR QUE GIRA CON RESPECTO AL ESTATOR; UNA BOLSA DE AIRE ENTRE AMBOS; LOS POLOS MAGNETICOS PERMANENTES DE LA MAQUINA (11) CADA UNO DE LOS CUALES INCLUYE UNA DERIVACION DE FLUJO (17) FORMADA POR DOS ELEMENTOS MAGNETICAMENTE CONTINUOS (18,19) DE UN MATERIAL CON UNA DENSIDAD DE FLUJO DE ALTA SATURACION. CADA UNO DE LOS PRIMEROS ELEMENTOS (18) SE EXTIENDEN DESDE EL NUCLEO POSTERIOR (16) HACIA ARRIBA, Y SU RESPECTIVO POLO (11) SE DIRIGE HACIA LA BOLSA DE AIRE DE LA MAQUINA Y ES MAGNETICAMENTE CONTINUO CON RESPECTO AL CITADO NUCLEO POSTERIOR (10). CADA UNO DE ESTOS ELEMENTOS (18) ES TAMBIEN ADYACENTE AL EXTREMO DE SU RESPECTIVO IMAN PERMANENTE, CONSTITUYENDO EL EXTREMO FUERTE, Y CUYO OTRO EXTREMO ESTA ALEJADO DEL NUCLEO (10) Y ES MAGNETICAMENTE CONTINUO CON RESPECTO AL SEGUNDO ELEMENTO DE LA DESVIACION DE FLUJO (19). CADA UNA DE ESTAS SE EXTIENDE DESDE EL PRIMER ELEMENTO Y DE FORMA CIRCUNFERENCIAL CON RESPECTO A LA MAQUINA HASTA EL EXTREMO DEL IMAN PERMANENTE (12) CORRESPONDIENTE, QUE HACE DE EXTREMO DEBIL. LA MAQUINA SE CARACTERIZA POR QUE EN EL SEGUNDO ELEMENTO (19) Y EN LA ZONA QUE SE ACOPLA CON EL IMAN PERMANENTE CORRESPONDIENTE (12) TIENE UNA FORMA TAL QUE EL AREA DE SU SECCION TRANSVERSAL AUMENTA PRACTICAMENTE DE FORMA LINEAL DESDE UN MINIMO EN SU EXTREMO LIBRE. CADA UNO DE LOS PRIMEROS ELEMENTOS DE LA DERIVACION (18) TIENE UN AREA DE SECCION TRANSVERSAL MINIMA IGUAL O MAYOR QUE EL AREA MAXIMA DE LA SECCION TRANSVERSAL DE SU SEGUNDO ELEMENTO (19) CORRESPONDIENTE, Y CADA DERIVACION (17) SE EXTIENDE POR ENCIMA DEL 80% DEL ARCO DE SU RESPECTIVO POLO, CONTANDO DESDE EL EXTREMO FUERTE.
