MDrive23Plus with Planetary Gearbox

The MDrive23Plus is available with a Planetary Gearbox option developed to increase torque at lower speeds, en-
able 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 Flange allows mounting the Planetary Gearbox to the load using a standard NEMA bolt
circle. Planetary Gearbox may be combined with other MDrive17Plus options, however are unavailable on Linear
Actuator versions.
