Abstract

SE TRATA DE UNA MAQUINA ELECTRICA CON UN INDUCIDO (1) EXCITADO POR UN IMAN PERMANENTE, EN CUYO PERIMETRO SE HAN DISPUESTO EN CADA POLO DEL INDUCIDO (N,S) VARIOS IMANES PERMANENTES EN FORMA DE PLACAS O TIRAS, DIRECTAMENTE EN EL ENTREHIERRO HACIA EL ESTATOR (1) DE LA MAQUINA. COMBINACIONES ENTRE LOS CAMPOS SUPERIORES DE LAS ARMONICAS DE LAS RANURAS DEL ESTATOR Y LOS CAMPOS SUPERIORES, QUE CONDUCEN A MOMENTOS PENDULARES A RAIZ DE LA DIVISION DEL IMAN, PUEDEN SER SUPRIMIDOS CONSIDERABLEMENTE, DEBIDO A QUE EL NUMERO TOTAL DE LOS IMANES PERMANENTES, DISPUESTOS EN EL INDUCIDO (5), CORRESPONDE A UN NUMERO PRIMO SUPERIOR A TRES.
