Motor sizing and torque delivery
The MH31401P17A2200 delivers 2.64 kW continuous power from a three-phase winding, with a nominal torque of 82.84 lbf.in (9.36 N.m) at 1000 rpm when paired with an LXM52 or LXM62 drive at 115 V three-phase input. Peak stall torque reaches 353.1 lbf.in (39.9 N.m) across the 115...480 V three-phase range, giving a 3.9× overload margin above the continuous stall torque of 91.2 lbf.in (10.3 N.m). The torque constant of 1.2 N.m/A at 120 °C copper temperature means the drive must supply 8.58 A continuous stall current to hold position at zero speed, and up to 29.8 A Irms for peak torque events.
Mechanical interface and mounting
Mounts via an international standard flange with a 5.5 in (140 mm) flange size, four 0.4 in (11 mm) mounting holes on a 5.1 in (130 mm) centring collar diameter, and a 0.1 in (3.5 mm) centring collar depth. The shaft measures 0.9 in (24 mm) diameter by 2.0 in (50 mm) long with a parallel keyway 0.3 in (8 mm) wide, and the overall motor body length is 6.0 in (152 mm). No holding brake and no second shaft end — the rear face is clear for an external brake or encoder if retrofitted, but the motor ships without either.
Feedback, cooling, and environmental rating
The Multiturn SinCos Hiperface encoder provides absolute position feedback over multiple shaft revolutions — the drive reads the full position on power-up without a homing sequence, which saves time on multi-axis machines. Cooling is by natural convection only — no fan or forced air required, so the motor runs silently and the IP65 rating is maintained across the entire housing. Electrical connection uses rotatable right-angled connectors, allowing the cable exit to be oriented in four directions to fit tight cable-tray routing.
Electrical parameters and drive matching
The 10-pole motor has a back EMF constant of 77.41 V/krpm, so at 4000 rpm maximum mechanical speed the generated voltage reaches about 310 V — within the DC bus of a 400 V-class drive. Stator resistance is 0.69 Ohm and inductance is 6.72 mH, giving an electrical time constant of about 9.7 ms — the drive's current loop bandwidth must be set accordingly to avoid overshoot. Maximum radial force Fr is 1930 N at 1000 rpm, derating to 1340 N at 3000 rpm — the bearing load limit governs belt-drive or overhung-load applications.
The sizing reference MH31401P and device short name MH3 identify this as part of the Schneider Electric MH3 series of servo motors, which covers the 1–3 kW range for general-purpose motion control.
