The MH31401P06F2200 is a 140 mm flange servo motor from Schneider Electric's MH3 series, rated 2640 W continuous power with natural convection cooling. The 10-pole rotor delivers 10.3 Nm continuous stall torque and 39.9 Nm peak stall torque, both specified at 115–480 V three-phase supply — the peak figure governs acceleration and emergency stop profiles on a machining centre or packaging line. The single-turn SinCos Hiperface encoder provides absolute position feedback on the first revolution, with sinusoidal commutation tracks for low-torque-ripple current control. The holding brake is rated 18 Nm holding torque and 18 W pull-in power. It locks the rotor at standstill with the shaft at rest — critical for vertical-axis Z drives where the load must not drift when the servo loop is off. The brake engages when power is removed; the 18 W coil draw means a standard 24 VDC supply can drive it without a separate brake rectifier.
Shaft, mounting, and environmental sealing
The motor has a 24 mm smooth shaft, 50 mm shaft length, and a 130 mm centring collar with 3.5 mm collar depth. The 140 mm flange uses four 11 mm mounting holes on the standard international pattern — it bolts directly to a NEMA 56C or metric 140 mm gearbox face without an adapter plate. IP65 rating means the motor body and connector housing are sealed against dust ingress and low-pressure water jets. On a food-packaging or washdown line, this motor can be mounted in the spill zone without a secondary cover — the rotatable right-angled connectors let the cable exit point away from the spray pattern.
Electrical parameters for drive matching
Stator resistance is 0.69 Ω and stator inductance is 6.72 mH — these set the electrical time constant and the current-loop bandwidth ceiling. The torque constant is 1.2 Nm/A at 120 °C copper temperature, and the back-EMF constant is 77.41 V/krpm. With a maximum current Irms of 29.8 A, the drive must supply at least that peak to reach the 39.9 Nm stall torque. Continuous stall current is 8.58 A at the 10.3 Nm rating. The brake pull-in power is 18 W — a standard 24 VDC brake supply with 0.75 A capacity handles it. The motor is wound for three-phase supply; nominal torque varies with input voltage (9.36 Nm at 115 V, 7.22 Nm at 400 V), so the drive's DC bus voltage directly affects available torque.
