Abstract
Accionamiento electromecánico perfeccionado, caracterizado esencialmente porque el par antagonista de potencia regulable esta constituido por un imán permanente ubicado en una cavidad de la base de soporte del conjunto de elementos integrantes del dispositivo, cuyo imán es mantenido aplicado contra el núcleo, siendo susceptible dicho imán de ser accionado en giro para obtener la orientación adecuada de su polaridad con respecto a la polaridad de la bobina.
Programmateur à dispositif de rotation pas à pas, permettant de faire varier automatiquement la fréquence des pas sans sources d'énergie autres que le moteur entraînnt l'arbre à cames
