Sizing and torque at the drive interface
The MH31001P02F2200 is a three-phase servo motor rated for 1520 W continuous output at 4000 rpm nominal speed. Nominal torque is 3.3 Nm when paired with an LXM52 drive at 115 V three-phase input, but drops to 2.9 Nm at 480 V three-phase — the torque derating table must be matched to the actual drive model and supply voltage, not just the motor nameplate. Peak stall torque reaches 10.8 Nm at 115-480 V three-phase, so the drive's peak current capability (11.2 A Irms max,) must be confirmed for acceleration profiles. The back EMF constant of 70.3 V/krpm means at 4000 rpm the motor generates ~281 V line-to-line — the drive DC bus must stay above this to maintain current control.
Brake and encoder — what locks and what tracks
The holding brake delivers 5.5 Nm (48.7 lbf·in) with a 12 W pull-in power — this holds a vertical axis without servo power, but the brake release time must be coordinated with the drive enable sequence to avoid dropping the load. Smooth shaft means no keyway; the coupling must be clamp-on type, sized for the 19 mm shaft diameter and 40 mm shaft length. The Multiturn SinCos Hiperface encoder provides absolute position feedback over multiple revolutions — no homing routine on power-up, which saves cycle time in pick-and-place or rotary indexing applications. The encoder resolution is set by the drive parameter, not the motor; confirm the drive supports Hiperface protocol before mating.
Mounting and environmental fit
Cooling is natural convection, so the motor must not be enclosed in a tight shroud; derate if ambient exceeds the 135 °C copper hot-spot limit. The 100 mm flange with 95 mm centring collar and 3.5 mm collar depth mounts to standard IEC B5 face. Rotatable right-angle connectors allow the cable exit to be oriented in 90° increments — useful when the motor is mounted in a tight corner and the cable must route away from moving parts. Radial force limits drop with speed: 900 N at 1000 rpm, 570 N at 4000 rpm. If the load is belt-driven, the belt tension must stay below these limits at running speed to protect the bearing.
Sourced through independent distribution channels against an RFQ. The part is genuine Schneider Electric, traceable to the factory.
