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
