Abstract
A system for processing a product includes a tool that processes the product and a rotor assembly including a rotor supporting the product and a stator with actuator(s) exerting torque on the rotor. A tool controller operates the tool and transmits speed request signals including a desired speed of the rotor and a control pulse having a threshold value repeating at the expiration of a period proportional to a desired rotation period of the rotor at the desired speed. A rotor controller receives both the speed request signal and the control pulse, controls the stator actuator(s) such that the rotor rotates at the desired speed and phase, and transmits a rotor position pulse and / or phase information to the tool controller once every predetermined angular displacement of the rotor. The tool controller operates the tool based on the angular position of the rotor as calculated using information from the rotor controller.
