Abstract

Machine pour moulage par injection utilisant des moteurs CC sans balais dans ses systèmes d'entraînement servocommandés. Lesdits moteurs CC sans balais confèrent au système une grande puissance à moindre coût, tout en gardant la simplicité inhérente aux moteurs CC à balais. En utilisant des codeurs à résolution accrue et en contrôlant la pression au moyen de la boucle de servomoteur pour le contrôle de vitesse, on diminue les variations du couple moteur et les oscillations à vitesse nulle.
