Uniform rotation speed, no step loss: we build strengthens PCB board in the motor, and adopts a unique stator technology to ensure that the stator teeth of the motor are uniformly and smoothly ground, the inner hole is high in precision The structure is stable, not jam: the surface of the motor rotor of our shop is coated with premium resin to seal the rotor as a whole, cured at high temperature. After the outer circle of the rotor is abraded and processed, there are no processing Stable speed and low noise: This motor has been tested on a variety of machines. The overall stability of the motor is high, the speed is uniform, and the noise is low Wide Application: This small stepper motors can be used in various area, such as 3D printer Current and power: When choosing a stepper motor, you need to pay attention to the rated voltage and current parameters. As long as the stepper motor drive unit can control the current output, in theory, any power supply voltage higher than the moto
