This 12V Φ50 mm brushed DC planetary gearbox motor (50WS78-12-S series) delivers a maximum torque of 22 N·m at a rated speed of 4 RPM (no-load speed 5 RPM) in its highest-torque configuration, with the series spanning no-load speeds from 5 RPM to 360 RPM and rated torques from 0.6 N·m to 22 N·m. It features Class B insulation and IP20 protection, with body lengths ranging from 147.8 mm to 191.7 mm and a weight of approximately 1.46–1.52 kg depending on the gear ratio. The integrated planetary reduction provides smooth, high-torque low-speed drive in a compact Φ45 mm frame, making it well suited to space-constrained applications in household appliances, office automation equipment, banking machines, medical devices, intelligent robots, and compact automation systems requiring reliable torque multiplication and quiet operation. Please specify the model number in the order note.
