Aim To introduce an indirect method to test the moment characteristics of a rotary disk-type synchrotron shutter with ballistic photogrammetry, the method is used to measure the synchronous shutter control system of a DC servo motor driven by a transmission mechanism in parallel. Armature voltage and current under no-load and load conditions.Methods The torque characteristics of the synchronized shutter were calculated by using the theory of electric drive.Results The torque characteristics were two crucial performance indexes to study the synchronization accuracy and shooting frequency stability The key and premise, the result of indirect test is consistent with the design value.Conclusion This method is effective and feasible
