Abstract
A multi-drive apparatus for phase shifters is disclosed. The disclosed multi-drive apparatus for phase shifters includes: a main-axle gear; a multiple number of output shafts each connected to a phase shifter; a multiple number of output gears coupled with the output shafts; and a cam part having the output shafts arranged on its upper surface, where at least one recess is formed in the upper surface of the cam part, and when at least one of the output shafts is inserted into the recess according to a movement of the cam part, then an output gear coupled with the output shaft inserted into the recess engages the main-axle gear. With the disclosed multi-drive apparatus, it is possible to drive multiple phase shifters using just two motors.
