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.

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.

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.

Product Description

Brushless Gearbox Motor 57BL03B-041AG26 NEMA23 24v 0.8ohms Customizable 57mm*57mm

Hetai prides itself on its research and development capabilities. With the support of professional laboratories and experienced technicians, Hetai has won 13 utility patents and awards such as high-tech enterprise awards.

Brushless gearbox motor mimics a planetary rotation system, the input shaft drives the central gear, also known as the sun gear, which then turns the surrounding gears, also known as planet gears. They also feature a very compact, low-weight design in their Class.planetary gears are used as speed reducers. They are used to slow down motors and increase the torque. Torque is the working power of the machine.
