In recent years, Silent has developed a micro-gear reducer for the drone field. The installation of this reducer significantly reduces the weight of drones without affecting their flight speed and quality. For example, drones with 4 or 6 engines must be equipped with high-power, high-speed gear transmission devices, gearboxes, reducers, and drive systems. The micro-gearbox of a drone must have the characteristics of high power, low energy consumption, small size, and low noise in order to meet the flight requirements of drones. Silent is a company that specializes in the research and development, design, and integrated manufacturing of gearboxes, micro- planetary gear reducers, and worm gear drive gearboxes. It custom-designs power gearboxes and other drive devices according to the performance requirements of drones.
