Abstract

CON EL OBJETIVO DE REDUCIR LAS VIBRACIONES PRODUCIDAS POR UN MOTOR Y MEJORAR LA RESISTENCIA AL CALOR, LAS PROPIEDADES DE FIABILIDAD, Y AISLAMIENTO DE VIBRACIONES SIN AUMENTAR EL COSTO O EL NUMERO DE FASES DE FABRICACION EN UN ROTOR PARA UN MOTOR MAGNETICO PERMANENTE, SE FORMA UN NUCLEO DE ROTOR CON UNA PARTE PERIFERICA EXTERNA MEDIANTE EL CUAL EL IMAN PERMANENTE ES FIJADO, Y UNA PARTE CENTRAL MEDIANTE LA CUAL SE FIJA UN ARBOL, SE PREVE UN ENTREHIERRO ENTRE LA PARTE PERIFERICA EXTERNA Y LA PARTE CENTRAL, Y SE CONECTA LA PARTE PERIFERICA EXTERNA A LA PARTE CENTRAL MEDIANTE UNA PLURALIDAD DE ELEMENTOS DE FIJACION. ASI, SE PUEDE OBTENER UN ROTOR QUE TIENE EXCELENTES PROPIEDADES DE AISLAMIENTO DE VIBRACIONES. YA QUE EL NUCLEO DEL ROTOR ESTA FORMADO DE PLACAS DE HIERRO LAMINADO SOBRE LAS QUE LA PARTE PERIFERICA EXTERNA, LA PARTE CENTRAL Y LOS MEDIOS DE FIJACION ESTAN TODOS FORMADOS COMO UNA SOLA PIEZA, SE PUEDEN MEJORAR LA RESISTENCIA AL CALOR, LA FIABILIDAD Y LA PROPIEDADES DE AISLAMIENTO DE VIBRACIONES SIN AUMENTAR EL COSTE O EL NUMERO DE FASE DE PRODUCCION.
