Headline torque envelope at 2000 rpm
Schneider MH31902P12A2200 carries a 29 N.m nominal torque at 2000 rpm on a LXM52 or LXM62 drive at 400 V or 480 V three-phase, which sets the sizing window for the driven load — the motor delivers continuous rated work without derating on either of those drive platforms.
Frame, feedback, and shaft interface
The 190 mm flange with 180 mm centring collar and four 14 mm mounting holes fits the international standard flange mount — the housing bolts to the gearbox or machine face directly without a transition plate. Feedback is a multiturn SinCos Hiperface encoder, and the parallel-key 38 mm shaft runs 80 mm long with a 10 mm key — the key width is the dimension that must match the mating coupling or pinion bore when this motor drops into an existing powertrain.
Electrical constants and thermal ceiling
Back-EMF constant 108.3 V/krpm and stator resistance 0.15 Ohm with 3.86 mH inductance define the drive-side current loop; the 135 °C copper-hot thermal ceiling is the limit the LXM drive firmware uses to fold back continuous current as the motor warms under load. Continuous stall current 30.8 A and maximum Irms 114 A bracket the drive sizing: 30.8 A is what the drive must hold indefinitely to produce 48 N.m of stall torque, while 114 A is the ceiling the drive can command during peak transients up to the 220 N.m peak torque.
Cooling, sealing, and wiring at the panel
IP65 standard sealing with natural-convection cooling and no holding brake means this motor relies on the ambient air around the housing for thermal rejection — it does not need a fan pack or brake rectifier on the cabinet wall, and the housing is rated for splash and dust exposure typical of factory floors but not for washdown. The 250 mm motor body carries rotatable right-angled connectors, so the power and feedback cables exit the housing in a configurable direction relative to the mounting face — useful in tight cabinets where straight connectors would clash with the drive or cable duct.
