A rotary drive is a mechanical system that converts linear motion into rotational motion. It typically consists of components like gears, motors, and shafts, which work together to create a circular movement. This type of drive is commonly used in various applications, including electric vehicles, industrial machinery, and robotics. Rotary drives can be powered by different energy sources, such as electricity or hydraulic fluid. They are essential in many devices, enabling functions like turning wheels, operating conveyor belts, and driving pumps. Their efficiency and reliability make them a crucial part of modern engineering and technology.
