The MDrive34 is available with a Planetary Gearbox
option developed to increase torque at lower speeds,
enable better inertia matching and produce fi ner
positional resolutions. These effi cient, low mainte-
nance Planetary Gearbox come fully assembled with
the MDrive and are offered in a large number of
MDRIVE34 WITH PLANETARY GEARBOX
PLANETARY GEARBOX MECHANICAL SPECIFICATIONS
Dimensions in Inches (mm)
Planetary Gearbox for MDrive34
reduction ratios in 1-, 2- and 3-stage confi gurations.
An optional NEMA Flange allows mounting the Plan-
etary Gearbox to the load using a standard NEMA
bolt circle. Planetary Gearbox may be combined with
other MDrive34 options, however are unavailable on
Linear Actuator versions.
