Portescap's h3 Hollow-Shaft Stepper Motor

March 29, 2010

h3 hollow-shaft stepper motors allow wires or other media to be routed through the shaft, reducing the space required of the motor solution.  The motors are available in NEMA 17, 23 and 34 frame sizes (short, one and two stack lengths available in each frame size), with hollow-shaft diameters of 4 mm, 7 mm and 11 mm diameters, respectively. The 1.8-degree step motors deliver up to 30+% higher torque and have an aluminum housing for superior heat dissipation and lower power consumption, Neodymium iron boron magnets for optimized torque density, and a bearing retainer and o-ring to help reduce motor noise.
