The package includes an integrated holding brake and a Hiperface multiturn absolute encoder, which together remove the need for an external brake rectifier and a homing switch on most return-to-position moves. In a panel build it drops onto an international-standard flange mount and talks to the drive through rotatable right-angled connectors, so cable dress can follow the cabinet rather than the motor. The intended pairing is the LXM52 or LXM62 drive family, where the encoder and winding are sized to land cleanly inside the drive's current loop. ## Continuous and peak torque envelope Continuous stall torque is 30 N.m at a continuous stall current of 23.2 A; holding torque (the static figure the brake holds against on a de-energised axis) is 32 N.m. Peak stall torque reaches 110 N.m for short dynamic moves, so the dynamic headroom above the continuous figure is roughly 3.7× — useful for acceleration spikes without oversizing the drive. Nominal torque lands at 16.5 N.m at 3000 rpm on the listed drive pairings, which is the right figure for sizing the drive's continuous current output rather than the stall figure above. The torque constant of 1.3 N.m/A at the 120 °C copper-hot reference means the drive current command translates almost directly to shaft torque once the thermal model is steady. ## Encoder feedback and brake integration The Hiperface multiturn SinCos encoder is the part that lets a high-end positioning drive close the loop on absolute position without a separate battery box on the motor. Multiturn means the axis retains its absolute position through power-downs up to the encoder's revolution memory, which is what most machine builders want for repeatable changeover on a servo press or pick-and-place axis. The integrated holding brake pulls in at 22.5 W; that figure is the holding coil power, not the peak inrush. The brake is sized to hold the shaft at zero speed against the rated holding torque, but it is not a dynamic stopping brake — designers still need a servo-controlled deceleration ramp for emergency stops, with the brake only dropping in once speed is near zero. ## Mechanical envelope and radial load Shaft geometry is 38 mm diameter by 80 mm long with a parallel key, and the centring collar is 180 mm at 4 mm depth — this matches the standard 190 mm flange footprint used across the MH3 family. Maximum radial force on the shaft varies from 2900 N at 1000 rpm down to 2600 N at 4000 rpm, so a belt drive or pinion pressing on the shaft end stays within the bearing load envelope across the operating speed range. Overall length is 9.8 in (248 mm), which is the dimension to check against the machine slide or gearbox housing before the BOM is frozen — shaft-end accessories add to this, not to the flange face. ## Thermal and electrical boundaries Cooling is natural convection — no integrated fan, no top-mount blower — so the rated continuous torque is valid only when the motor body is mounted to a surface that can sink the loss. IP65 means the housing is sealed against dust and low-pressure water jets, which suits a washdown-area machine tool or a food-line axis provided the cable glands match the same rating. Stator resistance is 0.24 Ohm with 5.08 mH inductance, and the back-EMF constant is 87.6 V/krpm — the back-EMF figure tells the integrator the motor will generate roughly 263 V at 3000 rpm, which has to be respected on any uncontrolled overhauling axis. Maximum RMS current is 89.6 A, which is the short-duration ceiling the drive's current limiter should be set below for normal operation.","metaTitle":"MH31901P17F2200 Servo Motor, 32 N.m, 3000 rpm, IP65","metaDescription":"Schneider MH31901P17F2200 servo motor, 32 N.m holding torque, 3000 rpm nominal, three-phase, IP65, with Hiperface multiturn encoder and holding brake.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"9.8 in (248 mm)","Category":"US1PC5218359","Key width":"0.4 in (10 mm)","Shaft end":"Parallel key","Encoder type":"Multiturn SinCos Hiperface","Second shaft":"Without second shaft end","Shaft length":"3.1 in (80 mm)","Holding brake":"With","Nominal speed":"3000 rpm LXM52 14.00 mA, 400 V, three phase 3000 rpm LXM52 14.00 mA, 480 V, three phase 3000 rpm LXM62 14.00 mA, 400 V, three phase 3000 rpm LXM62 14.00 mA, 480 V, three phase","Rotor inertia":"71.8 kg.cm²","Holding torque":"283.2 lbf.in (32 N.m)","Nominal torque":"146.04 lbf.in (16.5 N.m) LXM52 14.00 mA, 400 V, three phase 146.04 lbf.in (16.5 N.m) LXM52 14.00 mA, 480 V, three phase 146.04 lbf.in (16.5 N.m) LXM62 14.00 mA, 400 V, three phase 146.04 lbf.in (16.5 N.m) LXM62 14.00 mA, 480 V, three phase","Shaft diameter":"1.5 in (38 mm)","Torque constant":"1.3 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"6750 W","Mounting Support":"International standard flange","Sizing reference":"MH31901P","Back emf constant":"87.6 V/krpm","Device short name":"MH3","Motor flange size":"7.5 in (190 mm)","Peak stall torque":"973.6 lbf.in (110 N.m), 115...480 V, three phase","Stator inductance":"5.08 mH","Stator resistance":"0.24 Ohm","Brake pull-in power":"22.5 W","Maximum current Irms":"89.6 A","Nominal output power":"5.18 W, 400 V 5.18 W, 480 V","Centring collar depth":"0.2 in (4 mm)","Electrical Connection":"Rotatable right-angled connectors","Nbr. of units in pkg.":"1","Number of motor poles":"10","Temperature copper hot":"275 °F (135 °C)","Continuous stall torque":"265.5 lbf.in (30 N.m), 115...480 V, three phase","IP Degree of Protection":"IP65 standard","Maximum radial force Fr":"2900 N 1000 rpm 2750 N 2000 rpm 2650 N 3000 rpm 2600 N 4000 rpm","Mounting holes diameter":"0.6 in (14 mm)","Centring collar diameter":"7.09 in (180 mm)","Continuous stall current":"23.2 A","Maximum mechanical speed":"3800 rpm","Number of mounting holes":"4","Product or Component Type":"Servo motor","Speed feedback resolution":"16 periods","[Us] rated supply voltage":"115...480 V","Stator electrical time constant":"19.7 ms","Circle diameter of the mounting holes":"8.5 in (215 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://www.se.com/ie/en/product/MH31901P17F2200/mh3-servomotor-190mm-1-stack-keyed-shaft-sincos-multiturn-16-brake-angular-ip65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/MH31901P17F2200/alternatives.json"},"ai":{"faq":[{"question":"What is the listed phase and nominal torque on MH31901P17F2200?","answer":"Three-phase winding, nominal torque 16.5 N.m at 3000 rpm on the listed LXM52 and LXM62 drive pairings.
