Abstract
A method for controlling a pump motor associated with a component molding system includes applying a selected activation energy to the pump motor, driving, with the pump motor, a casting medium from a source to a mold through a casting medium delivery system, delivering the casting medium into a mold cavity, detecting one or more casting medium delivery parameters in the casting medium delivery system, detecting one or more casting medium mold parameters in the mold cavity, sending a first plurality of signals representing the casting medium delivery parameters to a controller, sending a second plurality of signals representing the casting medium mold parameters to the controller, processing the first plurality of signals and the second plurality of signals to determine pump motor control parameters, and adjusting the selected activation energy to the pump motor based on the pump motor control parameters.
