The rotary drive device is composed of a rotary device, a gearbox, and an electric motor, or a single device composed of a rotary device and a reduction motor. It is driven by an engine set at a certain speed. The motion of the rotary drive set on a horizontal or vertical plane (or in the case of a dual axis tracker moving simultaneously on both planes) so that the solar panel always faces the sun. According to the different positions of the sun during the day, the solar tracker and rotary driver accurately adjust the angle and inclination of the photovoltaic panel relative to the sun, thereby maximizing the electricity generated by the panel.
The rotary drive of a solar tracker is a complex solution that allows a device to solve the problems of rotation, motion, and power transmission.
The closed design of the rotary drive system provides good internal working conditions for the rotary bearings in the rotary mechanism. Usually, materials and seals are used for construction to achieve IP65 protection level. The high level of protection also ensures a longer product lifespan.
The slewing drive is designed with a self-locking rotating device to prevent unnecessary impact on photovoltaic solar panel units in severe weather conditions such as hurricanes and rainstorm.

Characteristics Of Slewing Drive
By adopting slewing bearing as its core component, slewing drive can bear axial force, radial force and tilting moment simultaneously. Slewing drive is widely applied in modular trailers, all types of cranes, aerial working platform, solar tracking systems and wind power systems.
Electric and planetary gearboxes can be designed according to customer's requirements. Slewing drive has the advantage for saving space in facilities, max load capacity in a compact design, extensive lifespan, and reduced maintenance costs.
Glossary
1) Tilting Moment Torque: Torque is the load multiplied by distance between the position of load and the center of slewing bearing. If the torque generated by load and distance is greater than the rated tilting moment torque, slewing drive will be overturned.
2) Radial load: Load vertical to the axis of slewing bearing
3) Axial load: Load parallel to the axis of slewing bearing
4) Holding torque: It is the reverse torque. When the drive is rotating reversely, and parts are not damaged,
5) The maximum torque achieved is called holding torque.
6) Self-locking: Only when loaded, the slewing drive is not able to reverse rotate and thus called self-locking.
