The MH31401P12F2200 is a three-phase servo motor from the Schneider Electric MH3 series, delivering 2640 W continuous power with a nominal torque of 9.36 N·m and a peak stall torque of 39.9 N·m across the 115–480 V three-phase range. The integrated holding brake holds 18 N·m static torque — enough to secure a vertical-axis load at standstill without the drive holding the position. Brake pull-in power is 18 W, so the 24 VDC brake supply needs to source that current during release. The multiturn SinCos Hiperface encoder provides absolute position feedback over multiple shaft revolutions — no homing sequence needed after power-up on a rotary axis. The encoder type is specified for the LXM52 and LXM62 drive families.
Nominal speed and torque across drive voltages
Nominal speed depends on the drive supply: 1000 rpm with 115 V single-phase input, 2000 rpm at 230 V single-phase, and 3500 rpm at 400 V or 480 V three-phase. The torque constant is 1.2 N·m/A at 120 °C copper temperature. Continuous stall torque is 10.3 N·m at 8.58 A continuous stall current — this is the torque the motor can hold indefinitely at standstill without overheating. The maximum RMS current is 29.8 A, which supports the peak torque of 39.9 N·m during acceleration. Stator resistance is 0.69 Ω and inductance is 6.72 mH — these values set the electrical time constant and influence the drive's current-loop tuning. The back EMF constant is 77.41 V/krpm, so at 3500 rpm the motor generates 271 V line-to-line back EMF.
Mounting, cooling, and environmental protection
The motor mounts on an international standard flange with a 140 mm flange size and 130 mm centring collar diameter. Four mounting holes at 11 mm diameter on the flange face secure it to the machine frame. Cooling is by natural convection — no external fan or liquid cooling required. The IP65 rating means the motor body and connector are sealed against dust ingress and low-pressure water jets, suitable for washdown areas in food processing or packaging lines. The shaft is 24 mm diameter with a parallel key, 50 mm shaft length, and 8 mm key width. The rotatable right-angled connectors allow the cable exit to be oriented in four positions — useful when the motor is mounted in a tight space with limited clearance. Maximum radial force at the shaft end is 1930 N at 1000 rpm, dropping to 1340 N at 3000 rpm — this limits the belt or direct-drive load the bearings can support without premature wear.
The motor is part of the MH3 series (sizing reference MH31401P) and mates with LXM52 and LXM62 servo drives. The electrical connection uses rotatable right-angled connectors — confirm the mating connector part number for your drive cable assembly. No direct pin-compatible alternative exists within the same family — the MH31401P12F2200 is a specific torque/speed/encoder variant. For a different speed range or feedback type, consult the MH3 series selection guide.
