Our nema 8 stepper motor is a stepper motor widely used in small 3D printers, robotic arms, drones, conveyors, and other miniaturized systems that demand high precision in tight spaces. Its flange size is 20mm*20mm, using 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 8 stepper motors perform well, and their static torque is relatively high, usually up to 300g.cm. In addition, the nema 8 stepper motor provides a variety of customized options in the design, such as output shaft type, connector, brake,encoder and gearbox, etc. Users can flexibly choose according to actual needs..
