In photovoltaic photothermal systems, in order to make the concentrator (reflector or other concentrating device) always face the sun, the slew drive is used to control the rotation of the concentrator. By adjusting the direction of the concentrator in real time, the system can maximize the use of solar energy and ensure that the light is accurately concentrated on the collector.

Structure: A typical slew drive structure includes inner and outer rings, gear systems, motors and control systems. The gear system is driven by the motor to rotate the inner ring relative to the outer ring.

Application: slew drives are widely used in industrial machinery, solar tracking systems, robotics and other fields, where large torque and high-precision rotary motion are required.
