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.

57BL03B-041AG26 micro low noise powder metallurgy geared NEMA23 brushless DC motor
Wide Speed Ratio with a Long Service Lifespan
57BL03B-041AG26 is consists of a 3 phase 57mm dc brushless motor and a 56mm planetary gearbox. The housing material of the gearbox is powder metallurgy. It uses sleeve bearing. The radial load(10mm from flange) of gearbox output shaft is 450N, and the shaft axial load is 200N.
For the same amount of load capacity, our powder metallurgy planetary gearbox has a higher service lifespan than the traditional gearboxes. The key aspects are to improve efficiency and reliability in any mechanical system.

A planetary gearbox, also known as an epicyclic gearbox, is one of the most interesting types of gearboxes available within motion control. They are often used in automotive as an important part of automatic transmissions.
How Does a Planetary Gearbox Work?
The alignment of the gears can be compared to our solar system where the planets revolve around the sun, hence the name “Planetary Gearbox”.
