    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 do brushless motors work?

Brushless motors work by alternating the polarity of the windings on the interior of the motor. The magnetic fields created when the coils are generated exert a push/pull force on the permanent magnets arranged around the outside of the casing.


On a brushless DC motor, it is not the motor shaft that rotates, but rather the outside case. Because the central shaft, to which the windings are attached, is stationary, power can be delivered directly to the windings, eliminating the need for brushes.
