Intelligent Motion Systems MDM42 AC MDRIVE42AC Plus with Planetary Gearbox, PM120 Model

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 finer positional resolutions. These efficient, 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 configurations. 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.
