Abstract
A ramp-up optimizing vacuum pump system comprising a vacuum pump in fluid communication with a blower and one or more apparatus and operable to create a vacuum flow from the one or more apparatus through the outflow of the vacuum pump. The blower is positioned between the vacuum pump and one or more apparatus. The blower includes a blower motor which is controlled by a blower controller and a unit controller. The unit controller increases the blower speed at a predetermined ramp-up rate. The blower controller optimizes the ramp-up rate of the blower based on the operating conditions by monitoring the current draw of the motor and the blower speed. If at any time the current draw exceeds a predetermined maximum at a certain blower speed, the blower controller maintains the blower speed until the current draw decreases below the maximum and then continues ramp-up up at the predetermined ramp-up rate.
