57BYGH636-79AG6 high torque 1.5V 3A Powder metallurgy stepper gearbox motor IP40
57BYGH636-79AG6 is consist of a DC 57mm stepper motor and a 56mm planetary gearbox. With the same load capacity, our powder metallurgy planetary gearbox has a higher lifespan than the traditional gearboxes. The key aspects are to improve efficiency and reliability in any mechanical system. There're also some cost-effective choices of material such as zinc alloy and engineering plastic.
This model is using a 56mm powder metallurgy gearbox, which can choose from the following reduction ratio:
Stage 1
1/4, 1/6
Stage 2
1/15, 1/18, 1/26
Stage 3
1/47, 1/66
