Single Axis Slew Drive With Electric Motor PV Solar Tracking System
Single Axis Slew Drive Description
The key components of a slew drive include the outer housing and
gear and the driving motor. The gear is fixed to the equipment or
structure, and is connected to the load or the part that needs to
be rotated. The motor drives the worm and gear, which, in turn,
rotates the entire assembly.
Slew drives are designed to provide precise motion control and high
torque output while maintaining compact dimensions. They often
incorporate worm gears or other types of gearing systems to achieve
this. The gear ratio of a slew drive determines the speed and
torque characteristics of the rotation. By adjusting the gear ratio
and controlling the motor speed, the rotational speed and
positioning accuracy can be tailored to suit specific requirements.

Applications
Slewing drive application are usually found in such as: wind
turbines, heavy load transporters, solar trackers, harbor cranes,
hydraulic equipment, crane steering mechanisms, automation systems,
heavy load manipulators, yaw and pitch control tables. The
versatility, robustness, and ability to handle heavy loads make
slewing drives suitable for a wide range of applications. They
offer precise control, durability, and reliability, making them an
integral component in many industries that rely on controlled
rotation or slewing motion.
