24VDC VE5 Slewing Drive 800Nm Torque for Solar Tracker Systems in Parabolic Trough Applications

The VE5 slewing drive with a 24VDC electric planetary gearbox is a compact, high-performance rotary solution designed for solar tracker systems in parabolic trough power plants (PTPP). Engineered for precision and durability, this vertical 5-inch slewing drive ensures optimal alignment of parabolic reflectors, enabling maximum solar energy concentration.

Built with an integrated worm gear and slewing bearing structure, the VE5 provides reliable motion control, high load capacity, and long-term stability in outdoor environments. It is an ideal choice for EPC contractors, solar project developers, and industrial system integrators targeting efficient solar thermal power generation.

Solar tracking systems often face performance limitations due to:

Inconsistent tracking accuracy reducing thermal efficiency

Weak structural resistance under wind and dynamic loads

Premature wear caused by dust, moisture, and temperature fluctuations

Lack of reliable holding torque leading to system instability

These issues can increase maintenance costs and lower overall ROI in solar power projects.

The VE5 slewing drive is engineered to overcome these challenges with a robust and precise design:

Precision control within ≤0.1° ensures accurate solar alignment

High holding torque (9200 Nm) guarantees anti-backlash stability

Self-locking mechanism enhances operational safety

Sealed structure with high IP rating extends service life

This solution improves energy yield, reduces downtime, and ensures long-term operational reliability.

The VE5 solar tracker drive is widely deployed across multiple solar and industrial scenarios:

Parabolic trough solar thermal power plants

Solar tracking systems for CSP (Concentrated Solar Power)

Linear solar concentrators

Renewable energy infrastructure projects

It is particularly suitable for large-scale installations requiring high precision and stability under continuous operation.

The VE5 slewing drive operates by converting electrical energy into controlled rotational movement. The 24VDC motor drives the planetary gearbox, which transmits torque to the worm shaft.

The worm engages with the slewing ring gear, enabling smooth and precise rotation of the connected structure. Due to the self-locking characteristic of the worm gear system, the drive maintains its position without additional braking systems, ensuring safety and energy efficiency.

To select the right slewing drive for your solar tracking system, consider:

Ensure axial, radial, and tilting loads are within rated limits to guarantee durability.

Match the output and holding torque with reflector size and environmental loads (e.g., wind pressure).

High-accuracy drives (≤0.1°) are essential for maximizing solar energy capture.

Choose products with high sealing performance for harsh outdoor environments.

Look for flexible configurations including motor types, mounting dimensions, and RAL color customization to fit project specifications.
