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.

Product Description

Brushed DC Motor Working Principle
When power supplies to the motor through battery or any DC source, electricity flows from the source to the armature through the brushes which usually locates on opposite sides of the motors shaft. Brushes are the very importent part of this motor. These brushes transfer electric current to the armature through physical contact with the commutator.
As soon as the armature coil gets energy or power, it begins to behave like a magnet. And at this point its poles start repelling the poles of the permanent magnet which makes up stator. As the poles repel, the motor shaft where the armature coil attached begins to rotate with a speed and torque. The Speed and torque depends on the strength of the magnetic field around the armature.
Usually the strength of the magnetic field is a function of the voltage applied at the brushes and the strength of the permanent magnet used for the stator.
