Portescap, West Chester, PA, has introduced hollow-shafted versions to its revolutionary family of h3 stepper motors. Hollow shaft models promise increased design flexibility by allowing wires or other media to be routed through the motor shaft, effectively reducing the space required of the motor solution. H3 hollow shaft step motors are available in NEMA 17, 23 and 34 frame sizes, with hollow shaft diameters of 4, 7, and 11mm in diameter, respectively.

These 1.8-degree step motors feature a unique design that enables them to deliver up to 30% higher torque than traditional hybrid step motors. They incorporate an aluminum housing for superior heat dissipation and lower power consumption, neodymium iron boron magnets for optimal torque density, and a bearing retainer and o-ring to help reduce motor noise. Larger bearings enable the motor to effectively handle higher side and radial loads.
