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.

Jim S**Please develop more low noise gearbox and with better prices, so we can sell your products to more clients and gain larger markets. Thank you.

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;

*Products can be customized by special request.
Advantages:
*Higher efficiency and power density than induction motors.
*Long service life and quiet running thanks to precision ball bearings.
*Wide speed range with full motor output due to linear torque curve Reduced electrical interference emission.
*Mechanically exchangeable with stepper motors, hence less construction expense and greater parts variety.
