    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

42BYGHM201-02 0.4A Nema17 Customizable Low Noise Hybrid Dc Stepper Motor


The stepper motor working principle is Electro-Magnetism. It includes a rotor which is made with a permanent magnet whereas a stator is with electromagnets. Once the supply is provided to the winding of the stator then the magnetic field will be developed within the stator. Now rotor in the motor will start to move with the rotating magnetic field of the stator. So this is the fundamental working principle of this motor
