MDRIVE42AC PLUS WITH PLANETARY GEARBOX
The MDrive42AC Plus 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 maintenance Planetary Gearbox come fully assembled
with the MDrive and are offered in a large number of reduction ratios in 1-, 2- and 3-stage confi gurations. An optional NEMA Output
Flange allows mounting the Planetary Gearbox to the load using a standard NEMA bolt circle. Planetary Gearbox may be combined
with other MDrive42AC Plus options, however are unavailable with Linear Actuators.
