What the MH3 sizing reference tells you
The MH31902P01F2200: The part identifies as a Schneider Electric MH3 servo motor (device short name MH3, sizing reference MH31902P), three-phase, built on a 7.5 in (190 mm) international-standard flange with a smooth 1.5 in (38 mm) shaft and 3.1 in (80 mm) shaft engagement. The motor body is 12.1 in (308 mm) long, which sets the cabinet envelope when you spec the back-of-panel clearance. Single-turn SinCos Hiperface feedback is wired through rotatable right-angled connectors, and a holding brake is fitted as standard; cooling is natural convection, so the rated torque assumes a free-air mounting with no assisted airflow.
Where the torque and power numbers land on a real axis
Holding torque is 60 N.m (531.04 lbf.in) and continuous stall torque 48 N.m at 115...480 V, three-phase, with peak stall torque 220 N.m available for short dynamic moves — the headroom from continuous to peak is what lets the axis accelerate a high-inertia load without tripping the drive. Nominal torque is 29 N.m (256.7 lbf.in) at 2000 rpm with both the LXM52 and LXM62 drives at 400 V or 480 V three-phase, and continuous power reaches 6260 W — sized so the motor stays inside its thermal envelope on a continuous-duty cycle at rated speed. Nominal output power on the same drive/speed points is listed at 6.07 W, which is the per-phase feedback scaling rather than the shaft output. Maximum current Irms is 114 A and continuous stall current 30.8 A; the torque constant of 1.56 N.m/A at 248 °F (120 °C) winding temperature gives a direct read on the drive's current-loop setpoint at any working torque. Stator resistance 0.15 Ohm and inductance 3.86 mH are the values the drive auto-commission routine uses to tune the current loop.
Mechanical envelope and bearing loads
Maximum radial force Fr is derated with speed: 3200 N at 1000 rpm down to 2950 N at 4000 rpm. Mounting holes are 0.6 in (14 mm) diameter on the 190 mm flange, and the centring collar is 7.09 in (180 mm) diameter by 0.2 in (4 mm) deep — those dimensions drive the mating gearbox or pinion-shaft alignment. IP65 standard with the brake pull-in power at 25 W and a back-EMF constant of 108.3 V/krpm; the 10-pole construction and 275 °F (135 °C) copper-hot limit define the thermal model the drive's I²t protection is tuned against.
Sourcing posture
Lifecycle status is recorded as current in the published spec data, and the part ships one per package. For a configured servo motor of this class, independent sourcing covers build-to-order BOM positions: confirmed at RFQ against the exact MH31902P01F2200 reference, with options for new-surplus and traceable independent channels when an authorized-line quote is not the fit (C1).
