This is geninue Moons brand stepper, Moons is one of the world’s largest stepper motor factories.
This stepper has very low resistance and inductance, running smooth, low noisy, and perfect for high-speed.
Also it can stand DC 60V at most, if you want to use 48V high volt it also works very well.
● High Torque, Low Losses, Small Size, High Efficiency
● Low Temperature Rise: Ideal for 3D printers, significantly less heat than other extruder motors
● Quieter & Smoother: Improved manufacturing processes makes these motors have a higher precision and more stable
