57mm Nema 17 Brushless DC Motor 10A 251W 8Pole 24V 36V 3Phase 0.8Nm 3000RPM
57BLF series is a type of Brushless DC Motor with a cylindrical body. The speed is ranging from 2500 rpm-3000rpm, and the rated torque is from 0.2 to 0.8 NM.
A Brushless DC Motor motor takes the advantages from AC, DC and Universal motor types and combines them into one unit. It has the long life, low maintenance, quiet operation, and variable speed ability of an AC motor; the high starting torque and linear speed-torque curve of a DC motor; and like both AC & DC motors, it works well with gearboxes. Brushless DC motors have a high power density, second only to the Universal motor, and they have the best efficiency rating of 65 to 80 %.
