    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.

Product Description

Gearbox Nema 11 28 BYGH Stepper Motor 4.22 V 1.8 Degree Micro High Quality With ROHS

 

The 28BYGH Stepper Motor is made of 32MM-51MM silicon steel sheet and rare earth magnetic steel. The air gap is small and the torque is large. It has the advantages of high anti-resonance characteristics and low heat generation.

 

Another reason to use a gearbox with a stepper motor is to increase the torque available to drive the load. When the load is driven by a motor-gearbox combination, the gearbox multiplies the torque from the motor by an amount proportional to the gear ratio and the efficiency of the gearbox.
