Sizing the MH3 against the drive
Schneider Electric MH31902P12F2200 is a three-phase servo motor in the MH3 family with a 190 mm international-standard flange, sized for the mid-torque axis on a packaging or material-handling line. Peak stall torque is rated 1947.2 lbf·in (220 N·m) at 115–480 V three-phase, which sets the acceleration headroom for the machine cycle; the motor delivers 6260 W of continuous mechanical power through natural convection, so no external fan is required and the cabinet thermal budget only has to clear stator copper losses.
Encoder, brake, and feedback
Position feedback is a Multiturn SinCos Hiperface encoder on the non-drive end, so the drive resolves absolute position over a single cable and the commissioning tool reads the electronic nameplate on first connection — no battery-backup encoder variant is required.
Mounting envelope and shaft
Overall length is 12.1 in (308 mm) with a 1.5 in (38 mm) parallel-key shaft running 3.1 in (80 mm) and a 0.4 in (10 mm) key, mounting through 0.6 in (14 mm) bolt holes on the 190 mm flange with a 0.2 in (4 mm) centring collar — a direct drop-in on the standard NEMA-style servo footprint for this frame size. The connection side uses rotatable right-angled connectors, so the power and feedback cables can be oriented to clear the cabinet gland plate without a separate adapter bracket, and the IP65 standard rating on the body and the seal side of the connector keeps the motor outside the cabinet on washdown-adjacent lines.
Mechanical and electrical limits
Maximum radial load on the shaft is rated 3200 N at 1000 rpm, stepping down through 3100 N at 2000 rpm, 3000 N at 3000 rpm and 2950 N at 4000 rpm — the pulley or pinion design has to land below the curve for the operating speed, not the headline stall number. Stator resistance is 0.15 Ohm with a 3.86 mH inductance, a back-EMF constant of 108.3 V/krpm and a torque constant of 1.56 N·m/A at 248 °F (120 °C) winding; with peak current Irms of 113.95 A the drive's current loop is sized to that ceiling rather than the nominal 19.3 mA reference figure. Copper hot temperature is rated 275 °F (135 °C) and cooling is natural convection, so the panel layout does not need to reserve airflow clearance above the motor body beyond the standard NEMA-style footprint.
