110 N.m peak from a 190 mm flange
The MH31901P16A2200 is a Schneider Electric MH3 series three-phase servo motor in the 190 mm flange size, sized for 6.75 kW of continuous power at 3000 rpm nominal speed with a peak stall torque of 110 N.m available across the 115 to 480 V drive range — meaning it absorbs high-inertia cycle loads (indexing tables, large conveyors, mixers, winders) without the drive having to oversize the frame just to cover the transient. A single-turn SinCos Hiperface encoder closes the feedback loop on absolute position within one turn — sufficient for most point-to-point motion where the absolute reference is taken from a homing move at power-up rather than from multi-turn battery backup.
Continuous 16.5 N.m, peak 110 N.m — read the duty, not the headline
Continuous stall torque is 30 N.m at 23.2 A with natural convection cooling, so the 16.5 N.m nominal figure already has the thermal headroom a packaging-machine or converting-line integrator expects at 3000 rpm with the LXM52 or LXM62 drive; sizing trips people up only when a designer assumes the 110 N.m peak figure is the continuous rating and walks into thermal trips. Maximum mechanical speed is 3800 rpm, while the electrical ceiling from the drive perspective is 89.6 A Irms — both numbers matter because exceeding the mechanical ceiling risks the bearing lubrication regime, not the winding insulation.
Rotor inertia and electrical constants
Stator resistance is 0.24 Ohm and inductance 5.08 mH, so copper loss at the 23.2 A continuous stall current sets the natural-convection thermal budget; this is a frame designed for clean industrial cabinets, not sealed oil-mist environments.
Radial load and shaft interface
Maximum radial force Fr derates from 2900 N at 1000 rpm down to 2600 N at 4000 rpm — a direct-coupled belt or pinion drive must stay within these limits or the bearing life collapses well before the winding does. The shaft is a 38 mm parallel-key configuration, 80 mm long with a 10 mm key, no second shaft end and no holding brake — meaning an external brake or backstopper has to be specified if the application holds a vertical load when the drive is de-energised.
Mounting and panel-side integration
International-standard flange mounting on a 180 mm centring collar with four 14 mm clearance holes keeps the motor within the IEC 60072 footprint family, so the existing machine baseplate accepts it without rework; rotatable right-angled connectors at the back simplify the cable routing into a tight cabinet. IP65 standard sealing on the housing supports washdown-adjacent food-and-bev and packaging lines — the connector face still needs its mating cordset sealed to keep the rating, since the IP figure is only as good as the cable entry.
Production status and sourcing posture
Production status is recorded as current on the lifecycle register; no official second source or factory successor is listed, so the BOM line is best held to the MH3 sizing reference MH31901P16A2200 as ordered.
