Feature:
HIGH TORQUE: Adopting high quality motor steel material,  3d printer stepper motor kit is provided with high torque  (0.4 Nm), low self inductance reactance, responsive and  can avoid system error.

LOW NOISE: The internal rotor of our anet anet a8 stepper  motor kit is made with introduced German craftsmanship and  there is rotor rubber covering the rotor, effectively  reduce the noise.

DURABLE & TOUGH: Our mini motor uses high hardness metal,  tough and durable. And the matte texture in the side wall  can increase friction.
WIDE APPLICATION: This small motors can be used in various  area, such as stage lighting; laser engraving; textile  machinery; medical equipment; placement machine; non- standard equipment; 3D printer; automation equipment, and  etc..

Warm tips:
Please note that this motor cannot be connected to the  power supply directly. It should be connected to a  constant current driver, otherwise, it will destroy the  motor. Please ensure that the output current is not higher  than the rated current of the motor (1.7A) .
