Product details

What this servo delivers in the drive line

The MH31902P11A2200 is a Schneider Electric MH3-series three-phase servo motor sized for sustained industrial motion — 29 N.m nominal torque with a 48 N.m continuous stall rating, so it can hold position against load without saturating the drive (cites:,). Continuous output is rated 6.26 kW, which sets the steady-state heat the panel has to dissipate around the motor flange (cites:). Peak stall torque reaches 220 N.m (1947.2 lbf.in) across the 115 to 480 V three-phase range, giving the drive headroom for acceleration transients that exceed the continuous rating (cites:). The motor delivers that envelope when paired with an LXM52 or LXM62 drive at 2000 rpm nominal speed and 19.3 mA, the operating point the catalogue publishes (cites:).

Encoder feedback and shaft interface

Feedback is a single-turn SinCos Hiperface encoder — an absolute position channel that also resolves the high-resolution incremental signals the drive needs for commutation (cites:). The mating connector is a rotatable right-angled connector, so the cable dress can be set after the motor is bolted into place (cites:). The shaft is 38 mm diameter by 80 mm long, parallel-keyed to 10 mm — a standard IEC interface that pairs with most gearbox input couplers of the same size class (cites:,). No second shaft end and no holding brake on this variant; order codes with a brake or second shaft end are separate positions in the MH3 family (cites:,).

Mechanical envelope and panel fit

The mounting is an international-standard flange, 190 mm flange size, with 4 holes on 14 mm bores — it bolts into the same footprint family as other MH3 190-frame motors, so a panel cut already qualified for this frame accepts the unit without redrawing (cites:,). Centring collar is 180 mm diameter by 4 mm depth, providing the registration the alignment pin keys against (cites:,).

Thermal limits and radial loading

IP65 sealing suits washdown-adjacent zones, but the housing is convection-cooled, meaning any enclosure that starves airflow around the body will trip the 135 °C copper-hot thermal limit (cites:,). Maximum mechanical speed is 3800 rpm, the ceiling before the bearings and balancing limit is crossed (cites:).
