QSH4218 Family

42mm/NEMA17 Bipolar Hybrid 1,8° Stepper (0,27-0,49 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.

There are versions with 10000 line (40000 cpr) optical incremental encoder with ABN interface available, suitable for closed-loop operation.
