ABSTRACT:
An injection molding machine utilizing vector controlled AC induction motors in its servomechanism drive systems. Vector controlled AC induction motors provide a cost effective high power drive system which superior performance capabilities. Further system efficiencies are realized when the control is configured to run multiple motors by multiplexing the computer controller circuits for the power sections of each motor.
