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
Nema 11 28 MM*28 MM Low Noise Dc Brush Gear Motor 5000 RPM 24 V
Brushed DC motors use an armature, which acts as a two-pole electromagnet. A commutator is a mechanical rotary switch that reverses the direction of current twice per cycle. In contrast, a brushless motor uses permanent magnets as its outer rotor. And brushless DC motors don't have brushes, which means they require less maintenance and are a bit more efficient than brushed motors.
Hetai's high power density BLDC DC small motor provides unparalleled speed and torque performance, ideal for automation applications such as electronic assembly equipment that requires constant pick and place operations. Durable and high-performance, energy-efficient Athlonix motors are also used in medical pumps, safety door locks, robotics and many other applications.

* 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.
