    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.

    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.

Product Description

57mm 24V Multi-metal 56W57BL03B-021 High QualityBrushless Dc Motor Nema 23

 

Brushless dc motors have significantly higher efficiency and performance, and a lower susceptibility to mechanical wear than their brushed counterparts. So if you're someone who does a fair amount of serious projects that require a drill, going with a brushless could make a lot of sense. It'll give you higher speeds and power, and require less maintenance.

 

The 57BL series is a cylindrical BLDC motor. The speed range is from 2500 rpm-3000 rpm, and the rated torque is from 0.057 NM to 0.44 NM.

The advantage of the 57 series is that:
● Excellent speed stability
● Compact and high power
● High efficiency and energy saving
● Low temperature rise, low noise, low vibration
● Long life and low maintenance cost
