Abstract: PURPOSE: A servo driving apparatus of a gimbal engine driving device is provided to remove the reciprocal interference effect by installing a spherical joint at an earth end part and a load end part and forming a universal joint with a gimbal structure. CONSTITUTION: An engine mount(3) is placed above a gimbal engine(1). A pitch axis controller(4) is installed at a pitch axis and a main axis controller(5) is installed at a main axis. A piston is installed in a cylinder. A load end bearing connected to the pitch axis or flank axis is provided in the piston. A magnet is fixed to an inner end of the piston. An earth end assembly is connected to the cylinder through a knuckle ring. A position detecting sensor is installed in a housing. A spherical joint is used in the load end bearing and the earth end assembly, and a universal joint is used in a gimbal engine shaft(2). A center axis of the load end bearing is connected to the engine mount(3).
