Peak stall torque reaches 110 N.m before the drive's 89.61 A three-second current ceiling clips the loop, and continuous stall sits at 30 N.m — that headroom is what lets the same motor punch through inertia peaks during accel/decel without tripping the drive. ## Drive loop electrical constants Back EMF constant of 87.6 V/krpm and torque constant of 1.3 N.m/A at 120 °C copper temperature define how the LXM52/LXM62 current loop closes around this motor; stator resistance of 0.24 Ohm and inductance of 5.08 mH set the electrical time constant that the auto-tuning routine will lock onto at first commissioning. ## Mechanical integration into the machine Mounting is via the international standard flange with a 180 mm centring collar and 14 mm mounting holes; maximum radial shaft load scales from 2900 N at 1000 rpm down to 2600 N at 4000 rpm so the gearbox or belt-drive designer has to budget the radial load against the operating speed, not the headline rpm figure. The 80 mm shaft with parallel key is the standard mating half for a gear coupling or pinion in this frame size, and without a holding brake the axis relies on the drive's deceleration ramp or a downstream mechanical brake for vertical-axis holding. ## Feedback, sealing, and thermal A SinCos multiturn Hiperface encoder feeds absolute position back over the rotatable right-angled connector, and IP65 sealing keeps the motor body washdown-tolerant for food-and-beverage or wet-process lines; natural convection cooling with a 135 °C copper hot-spot limit is the thermal envelope the drive's I²t model monitors.","metaTitle":"MH31901P12A2200 Schneider MH3 Servo Motor, 16.5 N.m","metaDescription":"Schneider MH3 MH31901P12A2200 AC servo motor, 16.5 N.m nominal torque at 3000 rpm with Hiperface multiturn encoder, IP65, flange mount.
