NEMA 17 (42 mm) BLDC Motors from Chinese Manufacturers

NEMA 17 (42 mm) brushless DC motors are used for small automation axes, medical devices, 3D printers and dispensers. By changing stack length and winding, Chinese factories typically build this frame from about 0.06 to 0.25 N·m continuous, up to 105 W, at 12 V / 24 V / 36 V.
