Kavitsu Slew Drive

Customer Challenge

A solar Kavitsu company was developing a large-scale solar farm that required an efficient tracking mechanism to maximize energy generation throughout the day.

The existing drive system faced several operational challenges:

• Inconsistent panel tracking accuracy
• Frequent maintenance due to dust and weather exposure
• Reduced torque under heavy wind loads
• High operational downtime
• Increased maintenance costs

The company required a compact, durable, and high-torque solution capable of delivering reliable performance in demanding outdoor environments.

The Solution

The customer selected the Kavitsu Slew Drive, designed with advanced hourglass worm technology and integrated slewing bearing technology.

Key product features included:

• Hourglass worm mechanism for higher tooth engagement
• High load carrying capacity
• IP65 sealed housing
• Hardened and ground worm gears
• Compact integrated design
• Self-locking capability
• Low maintenance requirements

These features allowed the tracking system to operate smoothly while maintaining precise panel positioning throughout the day.

Implementation

The slew drives were installed on multiple single-axis solar trackers across the project.

The implementation process included:

• System integration with tracker assemblies
• Torque verification under varying loads
• Alignment testing
• Environmental sealing inspection
• Performance testing during field operation

The compact design simplified installation while reducing the overall mechanical footprint.

Results

After deployment, the solar plant experienced several measurable improvements.

• Higher Tracking Accuracy

The precise rotational movement enabled the solar panels to follow the sun more accurately throughout the day.

• Improved Reliability

The sealed IP65 construction protected internal components from:

• Dust
• Sand
• Rain
• Outdoor environmental conditions
• Reduced Maintenance

The hardened gears and optimized worm design significantly reduced wear, resulting in fewer maintenance interventions.

• Better Load Handling
The slew drive maintained stable operation even during higher wind loads, improving overall system reliability.
• Longer Equipment Life
The robust mechanical construction increased the expected service life of the tracking system.
