The MH31003P12A2200 is a three-phase servo motor from the Schneider Electric MH3 series, sized for applications needing 3270 W continuous power at 4000 rpm nominal speed. Nominal torque depends on the drive supply: 8.45 Nm with LXM52 or LXM62 at 115 V three-phase, dropping to 6.25 Nm at 480 V three-phase — the torque constant is 1.17 Nm/A at 120 °C copper temperature. Peak stall torque reaches 27 Nm across the 115–480 V three-phase range, with continuous stall torque at 9 Nm and continuous stall current of 7.69 A — this sets the acceleration capability and holding force for the application. The Multiturn SinCos Hiperface encoder provides absolute position feedback over multiple revolutions, critical for applications that must retain position after power loss without a homing cycle.
IP65, natural convection, and mechanical limits — deployment constraints
Cooling is by natural convection — no external fan or forced air required, but the motor must be mounted with adequate clearance for airflow to avoid thermal derating above the 135 °C copper hot-spot limit. Maximum radial force at the shaft is 1050 N at 1000 rpm, derating to 610 N at 5000 rpm — this governs belt-drive or overhung load applications and bearing life. Motor flange size is 100 mm (3.9 in) with an international standard flange pattern, centring collar diameter 95 mm, and four 9 mm mounting holes — fits standard IEC B5 or B14 mounting interfaces.
