Single Axis Solar Tracker Gear Motor

The VH7 slewing drive is a robust solution designed for PV, CPV, and CSP solar tracker systems. As a pioneer in double enveloping slewing drive technology, this product ensures high performance in large-scale applications. Solar trackers significantly increase the efficiency of solar systems by providing more direct sunlight on the collectors. Depending on the location and specific system, energy harvesting can be increased by 25% to 40% compared to fixed systems. The slewing drive gear motor serves as the key mechanical component to ensure precise solar tracking.

Slewing drives function using standard worm technology, where the worm on the horizontal shaft acts as the driver for the gear. This mechanism reduces the speed of the driven member and multiplies its torque proportionally.

• Adopts plane secondary enveloping ring surface worm combined with slewing support for multi-tooth meshing.
• Optimized design: thinner overall thickness and reduced weight without sacrificing performance.
• The center features a through-hole design for versatile customer integration.
• High durability materials: 42CrMo worm with nitride treatment and 50Mn slewing bearing with quenched teeth for superior wear resistance.
• Strict quality control: ISO9001 certified production process with 100% finished product inspection.
