    NEMA 34 shaft diameter specification

    I recently ordered a NEMA 34 stepper motor and found the shaft diameter was 0.62" diameter. I was under the impression all NEMA 34 motors had a 0.50" diameter shaft.

    Just curious if the NEMA spec specifies shaft diameter, or is it just the frame mounting dimension?

    Thanks

    Is it maybe actually a IEC mount and a 16mm shaft?
