The SEW R47DRN90L4 is an integrated helical gear unit and AC motor drive product compliant with European CE 50 Hz standards.
It features an IE3 high-efficiency 4-pole motor with a rated power of 2 HP (approx. 1.5 kW) and supports S1-100% continuous duty. Through precision helical gear transmission, it achieves a gear ratio of approximately 21.81, reducing the motor input speed of 1900 rpm to an output speed of about 87 rpm. With a service factor of 1.4, it stably handles heavy-duty shock loads.
The IE3 efficiency design significantly cuts energy consumption, and its compact, adapter-free structure simplifies installation in space-constrained automated production lines and conveying equipment. Widely used in material handling, light industry machinery, and food processing, it is a preferred choice for reliable, high-performance industrial drive solutions.
