MDrive14 With Planetary Gearbox

Planetary Gearbox option for MDrive14Plus


MDrive14Plus, an integrated Microstepping Driver and NEMA 14 High Torque Motor, 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 rations in 1-, 2- and 3-stage configurations (see table below).

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 MDrive options, however are unavailable on Linear Actuator versions.
