5.67 Nm nominal torque, 18 Nm peak — what the torque envelope means for your axis
The MH31002P11F2200 delivers a nominal torque of 5.67 Nm and a peak stall torque of 18 Nm across the 115–480 V three-phase range. That 3.2× peak-to-nominal ratio means the motor can handle short-duration overloads during acceleration or reversing without dropping out of synchronism — a critical parameter when sizing for intermittent load cycles on a pick-and-place or indexing axis. The continuous stall torque is 6 Nm at 5.04 A continuous stall current, with a torque constant of 1.19 Nm/A at 120 °C. The back EMF constant of 78 V/krpm sets the voltage ceiling at higher speeds — match the drive bus voltage to ensure the motor can reach the commanded speed without field-weakening.
Encoder, brake, and IP65 — integration constraints for a maintained line
The single-turn SinCos Hiperface encoder provides absolute position feedback within one revolution — the controller reads the analog sine/cosine signals for fine interpolation. No multi-turn count is available from this encoder, so the drive must home on power-up if the axis requires absolute position across multiple revolutions. The holding brake is rated for 5.5 Nm holding torque and draws 12 W pull-in power. The brake is spring-applied, power-released — when the drive de-energizes, the brake engages mechanically, holding the load without power. Verify the brake release voltage matches the 24 VDC control supply typical in a cabinet. IP65 means the motor body and connector interface are sealed against dust ingress and low-pressure water jets — suitable for washdown environments in food processing or packaging lines. The rotatable right-angle connectors allow cable exit orientation adjustment during installation, reducing strain on the cabling.
Flange, shaft, and mounting — physical fit in a retrofit or new build
The motor flange size is 100 mm with a centring collar diameter of 95 mm and depth of 3.5 mm — this is the standard IEC 72-1 flange pattern for frame size 100. The shaft is 19 mm diameter with a parallel key, 40 mm shaft length, and a 6 mm key width. The overall length of the motor body is 202.3 mm. No second shaft end is available — the encoder is on the rear, not a through-shaft for a secondary encoder or tachometer. The mounting holes are 9 mm diameter on the flange; the centring collar ensures concentricity with the driven load.
The motor is part of the MH3 series, sized as MH31002P. The stator resistance is 1.97 Ω and inductance is 8.24 mH — these values support drive tuning parameter entry for current-loop gains. Natural convection cooling means no external fan or forced air is required, simplifying installation in confined cabinets.
