Why Choose the VE9 Solar Tracker Slew Drive?
1. Compact Design and High Torque Density
Unlike traditional rotary solutions that require separate gearboxes and mounting components, the VE9 integrates the slew gearbox and drive mechanism into a single compact unit to meet the rigorous demands of solar tracking applications. This design helps to:
Reduce installation space requirements
Simplify tracker structural design
Lower system integration costs
Improve on-site installation efficiency
2. Self-Locking Worm-Gear Mechanism to Withstand Wind Loads
Solar trackers operate in open outdoor environments where wind loads can generate immense impact forces. The VE9 utilizes an hourglass worm-gear design with inherent self-locking characteristics, maintaining the solar panel's position even when the motor is powered off.
Key advantages include: enhanced wind resistance, reduced risk of back-driving, improved tracker safety, and lower energy consumption during idle periods.
3. Integrated 24V DC Motor for Easy System Integration
The VE9 can be equipped with a 24V DC gear motor, providing a complete drive solution for PV tracking systems. It supports Hall sensor feedback. VE9 Slewing Drive Applications
