Abstract

Un motor 10 de PMDC tiene una caja 11 que acomoda los imanes 34 permanentes del estator y que forma una trayectoria de regreso de flujo. El espesor de la pared de la caja es de tal manera que la caja está magnéticamente saturada. Un anillo 30 de flujo se ajusta en la caja 11 alrededor de los imanes 34 permanentes. El anillo 30 de flujo tiene un espacio 35 considerable entre las orillas 36 opuestas del anillo. El espacio 35 en el anillo de flujo queda alineado con un espacio entre los imanes 34 permanentes de manera que la trayectoria de regreso de flujo en un lado del motor sea predominantemente a través de la caja solamente, mientras que en otro lado, es a través de la caja y el anillo de flujo ocasionado de esta manera un desplazamiento en el centro del campo magnético hacia el lado 31 con el anillo 30 de flujo.
