Features: brand new and high quality Adopting high quality motor steel material, is provided with high torque, low self-inductance reactance, responsive and can avoid system error.Low loss stators have better high speed performance. This 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. The 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 All parts are installed and debugged well, easily operate.Easy to install and simple structure. Lower noise, strong torque, stable property and high accuracy.
