ABSTRACT:
An electrostatic marking system is provided having a power source(s) in each of its processing stations. A specialized power source is made up of two stepper motors in operative connection to a planetary gearset. This gearset is comprised of a sun gear, a set of planet gears supported by a carrier, and a ring gear. This power source provides a continuously variable gear ratio between each stepper motor and its load.
