What the MH31903P11A2200 actually is on the shaft
The Schneider MH31903P11A2200 is the MH3-platform three-phase AC servo motor, sized MH31903P, that pairs with the LXM52 and LXM62 drive families and is framed for the standard international flange mounting footprint (190 mm flange, 14 mm mounting holes on a 180 mm centring collar).
Envelope figures that decide drive sizing
Continuous stall torque reaches 65 N·m at 36.1 A continuous stall current across the full 115 to 480 V three-phase range, with a peak stall torque of 330 N·m available on the same rail — the gap between 65 N·m continuous and 330 N·m peak is the acceleration budget the drive's motion profile will draw on. Maximum Irms is 124.5 A, the thermal ceiling the drive firmware respects on a fully-preconditioned motor. Back-EMF is 129.2 V/krpm and torque constant is 1.8 N·m/A at the 120 °C copper-hot reference — so a 65 N·m continuous stall pull corresponds to roughly 36 A of phase current, matching the continuous-stall figure directly. Stator resistance is 0.13 Ohm and stator inductance is 3.62 mH, the parameters the drive's current loop is tuned against. Maximum mechanical speed is 3800 rpm and maximum radial load on the shaft tapers from 3300 N at 1000 rpm down to 3100 N at 4000 rpm — the radial load envelope is the belt-pull or pinion-load ceiling a coupled gearbox or pulley must respect, especially on the long 80 mm shaft extension.
Thermal, sealing, and panel-side fit
Cooling is natural convection with a 135 °C copper-hot thermal ceiling — fan-and-forced-air kits do not apply to this SKU; mounting clearance around the frame is what carries the thermal budget. The IP65 standard rating seals the body against dust and low-pressure water jets, which fits the washdown and dirty-environment panel-side deployment typical for MH3 machines. Electrical connection is via rotatable right-angled connectors, so the cable exit angle can be set after the motor is bolted to the panel. The flange is the international standard with four 14 mm mounting holes through the standard 190 mm flange footprint, 4 mm centring collar depth, and 180 mm collar diameter — a direct drop-in for the MH3 reference builds. With ten motor poles the electrical cycle density is fine, and without a holding brake and without a second shaft end the package stays compact on the rear face.
Sourcing posture
The single-unit pack-out means spares are sourced per callout, and pairing with the LXM52 or LXM62 drive family is the expected control-side match.
