ST8918 high torque stepper motor - Nema 34

Stepper motor ST8918 - ST8918 high torque stepper motor - Nema 34

With the highest possible torque as well as compact dimensions (86x86mm -Nema 34) the ST8918 stepper motor series offers a high resolution and is employed with economically priced drives for precision speed and positioning applications. In conjunction with a microstep driver of the SMC series and with the same resolution of <0.36°, it constitutes an extremely cost-effective alternative to the multiphase stepper motors.
