    I purchased the 3-pack of the smaller steppers for my current ender 3 pro project. For my applications, they work perfectly. It's a great deal for quality motors, and I'm going to purchase another 10 packs.

    These are great motors and they are very strong. They are operating quietly, and also need them to release their hold every time a move is complete.

How Does a Planetary Gearbox Work?

The alignment of the gears can be compared to our solar system where the planets revolve around the sun, hence the name “Planetary Gearbox”.

 

In the middle of the planetary gearbox, there is a “sun” gear –also known as a central gear. This is often the input gear. Around the outside, there are 2 or more “planet” gears – or outer gears. Surrounding the planet gears there is a ring gear that holds the formation together. The planet gears are connected by a carrier which in turn is connected to the output shaft.
