Flange and shaft geometry that sets the cabinet cut-out
The MH31902P16A2200 sits in Schneider's MH3 servo line at a 190 mm flange size, with an overall body length of 9.8 in (250 mm) and a parallel-keyed shaft running 3.1 in (80 mm) out of the housing at 38 mm diameter — the kind of footprint that drops straight onto an international standard flange mount in a machine base or gearbox bell-housing. Centring collar registers at 180 mm diameter by 4 mm depth, with four 14 mm mounting holes, so the integrator's machined pad can be drilled to the standard MH3 bolt circle without adapter plates. Encoder feedback is single-turn SinCos Hiperface on a rotatable right-angled connector — the rotatable head keeps the cable entry clean against the cable track whatever the mounting orientation, and the parallel-keyed shaft end mates to a gear or coupling without a second shaft being presented to the driven machine.
Torque and power envelope against the LXM52 / LXM62 drives
Driven from the matched LXM52 or LXM62 servo drive on a 400 V or 480 V three-phase bus, the MH31902P16A2200 delivers a nominal torque of 256.7 lbf.in (29 N.m) at 2000 rpm in every one of the four listed drive/bus combinations on the spec sheet — meaning the motor's working point is fixed by the LXM platform family, not by the supply voltage across the 400–480 V window. Continuous stall current is 30.8 A against a maximum Irms of 114 A, which sets the drive's continuous/peak current parameter window; the integrator sets the drive's I²t trip from these two numbers rather than from the torque rating alone. Back-EMF constant 108.3 V/krpm and torque constant 1.56 N.m/A at 248 °F (120 °C) winding give the open-loop checks the commissioning engineer runs on first spin.
Mechanical limits, thermal envelope and sealing class
Cooling is natural convection — no integrated fan — so the panel-side thermal budget has to leave the motor body free of forced-air blanketing; the winding hot-spot ceiling is 275 °F (135 °C) and the IP65 standard sealing on the housing suits plant environments with splash and dust exposure but is not a washdown rating.
