Hollow Shaft Stepper Motor

Based on standard hybrid stepper motors, make the shaft to be hollow, FULLING offers stepper motors with hollow shaft in the sizes NEMA 11 (28 mm) NEMA 17 (42 mm) and NEMA 23 (57 mm). The hollow shaft can be used to pass cables or conduct laser beams through it in order to save space.
