Our nema 11 stepper motor is a stepper motor widely used in medical equipment, 3D printing, robots, CNC machine and other fields. Its flange size is 28mm*28mm, and it adopts a two-phase design with a step angle of 1.8 degrees. This kind of stepper motor has the characteristics of compact structure, light weight, high efficiency and low noise, and is suitable for applications with strict space requirements. In terms of performance, our nema 11 stepper motor performs well, with a holding torque range of 450g.cm~1200g.cm. In addition, nema 11 stepper motors provide a variety of customization options in the design, such as output shaft type, connectors, brakes, encoders and gearboxes, etc. Users can flexibly choose according to actual needs.
