Abstract

PROCEDIMIENTO PARA FABRICAR UN ROTOR PARA UN MOTOR ELECTRICO. SE DESCRIBE UN MOTOR ELECTRICO QUE INCLUYE UN ESTATOR CON UN NUCLEO DE] ESTATOR, UN DEVANADO DE ARRANQUE Y PRIMER Y SEGUNDO DEVANADOS PRINCIPALES. EL PRIMER DEVANADO PRINCIPAL Y EL DEVANADO DE ARRANQUE FORMAN UN NUMERO MENOR DE POLOS QUE EL SEGUNDO DEVANADO PRINCIPAL. EL NUCLEO DEL ESTATOR FORMA UN CONDUCTO DEL ESTATOR. EL MOTOR INCLUYE UN ROTOR CON UN EJE DEL ROTOR DISPUESTO CONCENTRICO Y AXIALMENTE EN EL NUCLEO DEL ESTATOR Y UN NUCLEO DEL ROTOR CONCENTRICO CON EL EJE DEL ROTOR. LOS CONDUCTORES DEL SECUNDARIO ESTAN DISPUESTOS AXIALMENTE EN EL EJE DEL ROTOR Y SE EXTIENDEN A TRAVES DEL NUCLEO DEL ROTOR. UNA PLURALIDAD DE IMANES PERMANENTES ESTAN SITUADOS EN UNA PERIFERIA EXTERIOR DEL NUCLEO DEL ROTOR, Y ESTAN MAGNETIZADOS PARA FORMAR UN NUMERO DE POLOS IGUAL AL NUMERO DE POLOS FORMADOS POR EL SEGUNDO DEVANADO PRINCIPAL.
