Product overview
The Size 14 (35 mm) hollow shaft stepper motor, available as models 14HS2033 and 14HS2045, delivers up to 0.36 N·m holding torque and is designed for compact industrial motion systems where a hollow shaft enables direct shaft-pass-through or encoder integration.

Torque performance curves
TEST CONDITION
Measured at 24 VDC using DS-OLS8-FRS4 bipolar chopper drive at rated current (RMS). Motor torque varies with supply voltage and drive settings; design margin of 50% is recommended for continuous industrial applications.
