Introduction to WF47DRN90L4 SEW Right Angle Gear Motor Reductors

The WF47DRN90L4 is a high-performance integrated right angle gear motor reducer launched by SEW, designed to meet the efficient transmission needs of various industrial scenarios. It integrates a motor and a reducer into one, featuring a compact structure, reliable performance and strong adaptability, which effectively saves installation space and improves the stability of the transmission system.

Equipped with a DRN90L4 electric motor, this gear motor reducer adopts advanced gear meshing technology, which minimizes friction and energy loss, ensuring a transmission efficiency of up to 93%. Its right angle design allows flexible power transmission in narrow spaces, making it suitable for equipment where the installation position is limited and the transmission direction needs to be changed.

The product adopts a robust aluminum alloy housing, which has excellent heat dissipation performance and corrosion resistance, effectively protecting internal components and extending the service life even in harsh industrial environments. It supports multiple installation methods, including foot-mounted and flange-mounted, and can be matched with solid or hollow output shafts to meet different load and connection requirements.

With a reduction ratio ranging from 3.2 to 75 and an output torque of up to 220Nm, the WF47DRN90L4 can accurately achieve speed reduction and torque increase, adapting to various speed and load demands. It is pre-filled with long-acting synthetic lubricating oil, realizing maintenance-free operation for a long time and reducing later use costs. This gear motor reducer is widely used in material handling, packaging machinery, light industry and other fields, providing a stable and efficient transmission solution for industrial production.
