The VE5 solar tracker slewing drive is a high-precision rotary actuator engineered for parabolic trough power plants (PTPP). Designed with a 24VDC electric planetary gearbox, it delivers stable and accurate tracking performance under demanding outdoor environments.
This vertical 5-inch slewing drive integrates worm gear transmission with a robust slewing bearing, ensuring precise positioning of parabolic reflectors to maximize solar energy capture. Its compact structure, high torque output, and self-locking capability make it ideal for large-scale solar thermal applications.
In solar thermal systems, inaccurate tracking and unstable positioning can significantly reduce energy conversion efficiency. Common issues include:
Low positioning accuracy leading to reduced sunlight concentration
Insufficient holding torque causing reflector drift under wind loads
Poor sealing performance resulting in shortened service life
These challenges directly impact power generation efficiency and operational reliability in PTPP projects.
The VE5 slewing drive addresses these challenges through optimized mechanical design and precision manufacturing:
High precision (≤0.1°) ensures accurate solar tracking
Strong holding torque (9200 Nm) prevents reverse rotation under load
Self-locking function enhances safety and stability
High IP protection improves durability in harsh outdoor environments
This combination ensures consistent reflector alignment, maximizing thermal energy collection and system efficiency.

The VE5 solar tracker drive is widely used in:
Parabolic trough solar power plants (PTPP)
Solar thermal energy systems
Linear Fresnel reflector systems
Industrial solar heating projects
It is particularly suitable for environments requiring high precision tracking and long-term outdoor operation.
The slewing drive operates through a worm gear mechanism driven by a 24VDC motor. The motor transmits rotational force to the worm shaft, which engages with the slewing ring gear.
This mechanism converts motor input into controlled rotational movement of the reflector structure. The self-locking feature prevents reverse motion, ensuring the reflector maintains its position even under external loads such as wind or vibration.
When selecting a solar tracker slewing drive, consider the following factors:
Torque Requirements: Ensure rated and holding torque meet system load demands
Precision Level: High accuracy (≤0.1°) is critical for solar tracking efficiency
Environmental Protection: Choose high IP-rated products for outdoor durability
Motor Compatibility: Select appropriate motor types (electric, hydraulic, stepper) based on control systems
Customization Needs: Verify availability of tailored designs and RAL color options
