MH3 servo, 190 mm flange, sized for mid-duty motion
The Schneider Electric MH31903P17A2200 is an MH3-series three-phase servo motor built around a 190 mm international-standard flange, with a 38 mm shaft and parallel key, 310 mm body length, and a centring collar depth of 4 mm — the geometry that drops into the standard mid-range servo mounting footprint on a machine base or gearbox input. IP65 ingress protection with rotatable right-angled connectors and natural convection cooling means the motor is specified for cabinet-adjacent or sealed-machine installations rather than open washdown; the encoder feedback is a multiturn SinCos Hiperface device, the bus-compatible interface that pairs directly with Lexium 52 and Lexium 62 drive families.
37 N.m nominal, 330 N.m peak — the torque envelope
Peak stall torque reaches 330 N.m across 115…480 V three-phase, with continuous stall torque of 65 N.m at 36.1 A and a maximum Irms of 124.5 A; the peak figure governs short-cycle accel/decel bursts (indexed moves, press feeds, vertical-axis lifting under hold) while the continuous figure governs any dwell that holds the rotor loaded — read both before picking this motor for a continuous-torque application.
Shaft, bearings, and the radial-load derating
Mounting is via four 14 mm holes on the international-standard flange, with a 180 mm centring collar; the brake option is omitted (without holding brake, without second shaft end), so any vertical-axis application needs a mechanical brake on the gearbox or a second-source motor with the brake option from the same MH3 family.
