CA 2168881

An injection molding machine utilizing vector controlled AC induction motors (103, 124, 148, 156) in its servomechanism drive systems. Vector controlled AC induction motors provide a cost effective high power drive system with superior performance capabilities. Further system efficiencies are realized when the control is configured to run multiple motors by including a multiplexer (192) for the controller CPU (190) to send signals to the power sections (194, 196, 198, 200) of each motor.

L'invention concerne une machine à mouler par injection utilisant des moteurs à induction C.A. à commande vectorielle (103, 124, 148, 156) intégrés dans ses systèmes d'entraînement à servomécanisme. Des moteurs à induction C.A. à commande vectorielle assurent un système d'entraînement grande puissance rentable présentant des capacités de rendement supérieures. L'efficacité du système est encore accrue lorsque la commande est configurée pour commander des moteurs multiples par l'addition d'un multiplexeur (192) permettant à l'unité centrale (190) de l'organe de commande d'envoyer des signaux aux organes d'alimentation (194, 196, 198, 200) de chaque moteur.
