High : 17HS3401 Adopting high quality motor steel material, is provided with high , low self-inductance reactance, responsive and can avoid system error.Low loss stators have better high speed performance. Low Resistance: can a lower resistance value compared to motors of the same thickness and . 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 area, such as 3D printer; stage lighting; textile machinery; placement machine; non-standard equipment; automation equipment etc. Colour:Photo Color Material:Metal Package Contents: 1 x Only the above package content, other products are not included.
