37 N.m at 2000 rpm — the sizing envelope
The MH31903P01A2200: On the paired Lexium 52 or Lexium 62 drive at 400 V or 480 V three-phase, it delivers 37 N.m of nominal torque at 2000 rpm — meaning a mid-size packaging machine, indexed conveyor, or rotary table sized for continuous motion in that torque band (citing,). The continuous stall torque ceiling is 65 N.m, with a peak stall of 330 N.m for the acceleration transient — the gap between nominal and peak is what lets the motor survive indexing moves and emergency stops without stalling the drive (citing,).
Hiperface feedback, rotatable connectors, IP65
Feedback is a single-turn SinCos Hiperface encoder — the absolute single-turn position the Lexium drive uses for commutation and torque control without a homing move at every power-up (citing). The connector exit is a rotatable right-angled plug, which lets the wireman orient the cable after the motor is bolted to the gearbox or coupling — useful in tight panels where a straight connector would not clear the structure (citing). IP65 on the standard housing covers dust and low-pressure water jets, so the motor survives washdown-adjacent zones on a food or pharma line when the cable gland is properly torqued (citing).
Flange, shaft, and radial load
Mounting is the international standard flange — 190 mm flange size with a 180 mm centring collar and four 14 mm mounting holes on the standard pattern, which bolts directly into a gearhead or a machine faceplate without an adapter plate (citing,). The smooth shaft is 38 mm diameter by 80 mm long, sized for the radial load envelope that drops from 3300 N at 1000 rpm to 3100 N at 4000 rpm — the right figure to check is the application speed, not the headline motor speed, because belt and gear radial load scales with rpm (citing,). Centring collar depth is 4 mm, so the pilot registers cleanly into the mating bore (citing).
Electrical constants and drive matching
Back-EMF constant is 129.2 V/krpm and torque constant is 1.8 N.m/A at the 120 °C copper-hot reference — these are the two numbers the drive sizing tool uses to land on the right continuous current, which sits at 36.1 A against a 124.5 A Irms maximum for short overload events (citing,). Maximum mechanical speed is 3800 rpm, so any application above that needs a gearbox or a different motor frame (citing).
