    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

28MM*28MM Nema 11 Compact In Volume Dc Brush Gear Motor 24 V

 

A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source and utilizing an electric brush for contact. Brushed motors were the first commercially important application of electric power to driving mechanical energy.

 

They are applied to:

1. In Automobile industry: various fan, wiper, spray pump, turbo timer, rearview mirror etc;

2. In Hotel: automatic door, automatic door locks, automatic curtain, automatic water supply system etc;

3. In Industry and agriculture: PMDC motors are widely used in electrical and automation control and instrumentation;

4. In Medical and healthcare industry: PMDC motors are used more widely, such as medical instruments, surgical tools, electric saws in open-brain surgery treatment;
