Are planetary gearbox good for high torque?
Planetary gears are designed to handle high torque in a compact space. They consist of three coaxial shafts with gears arranged in a way(distributes the load across multiple gears) that allows the transmission of significant torque while reducing speed.
Planetary dc geared motors are known for their high precision, torsional stiffness, and low backlash, suitable for a wide range of tasks, common in robotics, heavy machinery, automotive transmissions and industrial machinery.

I really like these little 28mm gear motors, they are precise, work well and you can’t beat the price, perfect for my company internship, what’s even more satisfying is that I asked the customer service if there were other small screws and brackets that I needed, and she found a way for me, which is great. These small screws are not so easy to find. I will buy again.
