Single Axis Vertical Slew Drive
Optimized for horizontal single-axis PV tracking systems, this compact and easy-to-install slew drive provides a practical solution for PV, CPV, and CSP solar tracking applications.
The integrated design combines a precision worm gear reducer with an optional drive motor, including servo, hydraulic, or brushless DC options. This helps reduce installation height, save space, and simplify setup without complex alignment.
The optimized double-enveloping tooth profile and hourglass worm structure improve contact ratio, load capacity, and resistance to eccentric loads.
- Designed for horizontal single-axis solar trackers (HSAT) and photovoltaic module arrays.
- Suitable for weather-resistant solar tracking applications where IP65 or higher protection is recommended, including desert, coastal, and plateau environments.
