Stober 1 Servo Gear Units

PHKX/PHK/PHQK Series: RIGHT ANGLE – Flange Output
Performance is dependent on several
factors including duty cycle, bearing design,
gearhead size and stage configuration,
among others.
Use the chart below for preliminary
evaluation, then use the following
performance chart and selection information
on the following pages for specific
performance sizing and selection.

1)
Ratings based on input speed (n 1
) of 2000 RPM.
For torque at higher input speeds (M 2NX
) solve the formula:
where n 1
= Actual Input Speed.

2)
Tested at 1.5% of nominal torque and recorded on the output side of the gearhead. For lower backlash, contact STOBER technical support.
3)
Measurement at one (1) meter distance with input speed (n 1
) of 2000 RPM.
4)
Rating based on output speed (n 2
) of 100 RPM. For values at other speeds see page 254.
