PRODUCT DESCRIPTION  

• High Torque: Twotrees stepper motor Adopting high quality motor steel material, is provided with high torque (42Ncm(60oz.in) ), low self-inductance reactance, responsive and can avoid system error.Low loss stators have better high speed performance.
• Low Resistance: Twotrees stepper motor can get a lower resistance value compared to motors of the same thickness and torque. This considerably increases the thermal conductivity of the motor. This effectively reduces the increase in temperature.
• Wide Application: This small stepper motors can be used in various area, such as 3D printer; stage lighting; laser engraving; textile machinery; medical equipment; placement machine; non-standard equipment; automation equipment etc.
• Excellent Service : CE certified：Each nema 17 stepper motor has undergone a rigorous quality control ex works, can carry out a 24-month quality assurance . If need further please feel free contact us, we very happy to assist you.
