ST5909 high torque stepper motor - Nema 23
The 0.9° stepper motors from Nanotec in the compact high torque ST5909 stepper motor series (56x56mm - Nema 23) present a more economic alternative to the motors of the ST5709 series. With the same technical characteristics, they are approx. 30% cheaper but reach the same performance.
Also this series has stepped windings and construction lengths for the most diverse speed requirements. If you want another winding, please contact us.
A positioning control of the SMC series enables an adjustable step angle of 0.9° to 0.007° per step, hence providing a real alternative to multiphase stepper motors.
