Single Axis Electric Motor Slew Drive, 30 Year Life, PV Solar Tracking System
Single Axis Slew Drive Description
A slew drive, also known as a slewing drive, is a compact and versatile gearbox mechanism used in various applications to provide rotational movement or positioning control. It consists of a combination of a gear set and a drive motor, typically an electric motor or a hydraulic motor.
The main purpose of a slew drive is to enable the rotation of a load around a fixed axis or to track the movement of a target. It offers a high torque output and the ability to withstand heavy axial and radial loads. Slew drives are commonly used in machinery and equipment that require precise and continuous rotation, such as solar tracking systems, cranes, wind turbines, satellite dishes, excavators, and industrial turntables.
