Rotary drives are applicable to any scenario requiring full rotation combined with speed variation. They represent the optimal solution for power transmission demanding high torque, motion transfer requiring high precision, or mechanisms with stringent requirements for compact and integrated structural configurations.
The most prevalent applications include full-rotation structures in engineering and construction machinery, as well as solar energy systems, wind power installations, and various long-term operational automated tracking mechanisms. Due to their compact structure and short transmission chain, rotary drives can relatively easily achieve high precision and are more amenable to digital control implementation. Consequently, they have also been widely adopted in industrial robotics applications.
