It is the 37 N.m frame: 37 N.m nominal torque and 9560 W continuous mechanical power when paired with an LXM52 or LXM62 drive at 400 V or 480 V three phase. The MH31903P06A2200 ships without a holding brake and without a second shaft end — feedback is a single-turn SinCos Hiperface encoder wired through rotatable right-angled connectors. ## Sizing the torque, current, and speed envelope Continuous stall torque is 65 N.m at 36.1 A across the full 115 V to 480 V three phase operating window; peak stall torque reaches 330 N.m — a 5× overload margin that the LXM52/LXM62 drive will deliver in S-curve accel/decel segments before tripping into the Irms limit. Maximum current is 124.5 A Irms and the motor's mechanical speed ceiling is 3800 rpm; nominal operating speed is 2000 rpm on the listed drive combinations, leaving roughly 1.9× mechanical headroom above the rated point. Torque constant is 1.8 N.m/A at the 120 °C hot-spot and back-EMF constant is 129.2 V/krpm — these two numbers scale together, so at 3300 rpm back-EMF is approaching the 480 V DC-bus limit and the drive will pull out of field-weakening before the motor does. ## Mechanical fit, bearings, and thermal envelope Mounting is an international standard flange at 190 mm, with four 14 mm mounting holes on a 180 mm centring collar and a 4 mm collar depth — the bolt circle and shaft height follow the IEC 72-1 interface, so any standard gearbox or planetary reducer with an MH3-compatible input mates directly. The smooth shaft is 38 mm diameter by 80 mm long, single shaft end with no second output — radial load capacity runs from 3300 N at 1000 rpm down to 3100 N at 4000 rpm, which is the bearing rating limit that drives coupling selection, not the motor's torque rating. Cooling is natural convection with a 135 °C copper hot-spot rating and IP65 sealing on the standard variant — for a washdown cabinet interior or a clean enclosure with no forced airflow on the motor body the thermal envelope is intact; a stainless or IP67-rated shaft seal is the upgrade path for direct food-zone mounting. ## Drive pairing and feedback wiring Stator resistance is 0.13 Ω and stator inductance is 3.62 mH — the low R/L ratio means high current slew under a step load, so the drive's current loop bandwidth needs to be sized for the 330 N.m peak rather than the 37 N.m nominal, or the cycle-time advantage of the high-inertia rotor is lost to controller lag. Hiperface SinCos single-turn feedback resolves absolute position within one mechanical turn and incremental position at the SinCos interpolation rate — the drive parameter set on the LXM52/LXM62 has a matching encoder profile, so commissioning does not require a third-party resolver-to-Hiperface adapter. ## Status, lifecycle, and sourcing posture No official successor or pin-compatible alternate MPN is on file for MH31903P06A2200 — the MH3 family uses the same IEC 72-1 mechanical interface across the 190 mm frame, but firmware, encoder resolution, and brake options differ between code variants, so any cross-reference needs to be against the precise code, not the family.","metaTitle":"MH31903P06A2200 Servo Motor, 37 N.m, Three Phase","metaDescription":"MH31903P06A2200 Schneider MH3 servo motor, three phase, 37 N.m nominal torque, 65 N.m continuous stall, 330 N.m peak, IP65.
