Rod S****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.

Sam N***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.

Nema 11 4.22V 0.67A 28YGH102-XXAG107 Cost-effective Gearbox Stepper Motor High Torque
Planetary gearboxes, also known as planetary gearboxes, are one of the most interesting types of gearboxes in motion control.
28YGH102-XXAG107 is one kind of micro motors.Its specific is low noise and high torque.The center of the input gear of the planetary gearbox rotates around the center of the output gear, and the input shaft and the output shaft are aligned. This shows that it is a gearbox with the same input and output rotation centers
This model is using a 28mm powder metallurgy gearbox, Design is quite complex thou they are efficient and still easy to maintain.
