MDRIVE34 WITH PLANETARY GEARBOX

The MDrive34 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 mainte- nance 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 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.
