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.

The 42BLY series is one of the most regular brushless motors applied in the automation industry.
Our 42BLY series brushless motor have the following advantages.One big advantage is efficiency, as these motors can control continuously at maximum rotational force (torque). Brushed motors, in contrast, reach maximum torque at only certain points in the rotation. For a brushed motor to deliver the same torque as a brushless model, it would need to use larger magnets. This is why even small BLDC motors can deliver considerable power.The second big advantage—related to the first—is controllability.
