SDE-PDE Series Slew Drives: Dual-Axis Precision for Solar and Industrial Innovation
What is an SDE-PDE Series Slew Drive?
The SDE-PDE Series Slew Drive is a dual-axis rotary actuator system combining two independently driven worm gears and slewing bearings. Designed to allow motion along both the azimuth and elevation axes, these drives are primarily used in dual-axis solar tracking systems, satellite antennas, and precision machinery requiring synchronized movement in two directions.
SDE stands for “Solar Dual-axis Enclosed,” while PDE refers to “Precision Dual-axis Enclosed.” Both versions are enclosed, sealed, and optimized for outdoor or high-performance industrial environments.
Key Features and Benefits
Dual-Axis Control in a Compact Unit
SDE/PDE drives offer synchronized movement on two axes using two separate worm gear systems, enabling smooth and precise tilt and rotation control.
Fully Enclosed, IP65+ Rated Housing
Built with sealed housings, these drives resist water, dust, sand, and UV, ensuring long-lasting operation in open-field solar or desert deployments.
High Load Capacity with Minimal Backlash
The combination of two slewing bearings and cross-mounted worm gears ensures strong torque output and high precision.
Modular Motor Compatibility
The drive supports DC, AC, and hydraulic motors. LDB provides dual-axis servo motor integration with encoder feedback for intelligent control systems.
Simplified Installation
With flange mounting options and symmetric design, the SDE-PDE drive can be easily configured to match a wide variety of panel, dish, or sensor layouts.
Application Scenarios
Dual-Axis Solar Tracking Systems: In photovoltaic and concentrated solar power fields to optimize sun alignment and maximize energy yield.
Radar and Communication Antennas: Ensuring stable, continuous positioning for moving targets and changing angles.
Astronomy and Telescopes: Precision sky tracking in observatories and satellite uplinks.
Heavy-Duty Surveillance Cameras: Where smooth pan-and-tilt functionality is required.
Test Benches and Gimbal Systems: Industrial test setups needing coordinated motion simulation.
