Natural convection cooling means the thermal envelope is set by the motor's own surface area on the machine frame — no external fan or blower is required to hold the published torque curve, which simplifies cabinet integration but demands derating headroom in fully enclosed panels. ## Torque and speed envelope across the drive pairings That means the same mechanical axis behaviour is delivered at the two common industrial supply voltages — the integrator picks the drive by I/O and safety architecture rather than by torque curve. Peak stall torque reaches 330 N.m for short dynamic events (115...480 V three-phase), giving roughly a 5.5:1 peak-to-continuous margin for acceleration and deceleration ramps. Maximum mechanical speed is 3800 rpm, so any gearing ratio selected above 1.9:1 from a 2000 rpm base must respect the upper speed cap rather than the nominal point. ## Shaft, bearings, and radial load budget The output is a 38 mm smooth shaft, 80 mm long, with no second shaft end — a single-ended configuration that simplifies the coupling choice and the guarding envelope. Centring collar is 180 mm diameter, 4 mm deep, on a 190 mm international standard flange with 14 mm mounting holes, fitting the standard machine-builder foot pattern. Maximum radial force Fr is derated from 3300 N at 1000 rpm down to 3100 N at 4000 rpm — the small step reflects the bearing's speed-squared load envelope rather than a hard speed limit. For a belt-driven axis, this curve dictates the minimum pulley diameter; for a directly coupled gearbox, it sets the maximum overhung load the input pinion can apply at the operating point. ## Brake, thermal limits, and pole count An integrated holding brake is fitted with a 25 W pull-in power — enough to hold the axis at standstill with the 60 N.m rated holding torque, typically engaged after the axis stops to remove heat from the brake coil during continuous motion. The 10-pole construction is what produces the smooth low-speed behaviour observed on this frame; combined with stator resistance 0.13 Ohm and stator inductance 3.62 mH it sets the drive's current-loop bandwidth. Thermal copper-hot ceiling is 135 °C, which is the temperature the drive uses to derate the continuous torque curve when the motor is enclosed in a cabinet without forced airflow. A 10-pole servo with these constants typically demands either a finned mounting surface or a cabinet fan to sustain the nominal 37 N.m in a fully sealed enclosure. ## Lifecycle status and sourcing Specified into a machine builder's BOM, MH31903P01F2200 is quoted to order against the RFQ with the cable set, connector orientation, and brake option confirmed against the project drawing.","metaTitle":"MH31903P01F2200 Schneider MH3 Servo Motor, 60 N.m, 2000 rpm","metaDescription":"Schneider MH31903P01F2200 servo motor, 60 N.m holding torque, 2000 rpm, IP65, single-turn SinCos Hiperface encoder.
