57mm/NEMA23 Bipolar Hybrid 1,8° Stepper (0,55-1,89 Nm)

These two phase hybrid stepper motors are optimized for microstepping and give a good fit to the TRINAMIC family of motor controllers and drivers. They can be used in very space critical applications and allow high RPM due to their low back EMF.
