The MH31002P11A2200 is a three-phase servo motor from Schneider Electric's MH3 series, delivering 2270 W continuous power at 4000 rpm nominal speed. The 6 Nm continuous stall torque (5.04 A) is the thermal steady-state limit for holding or constant-torque applications; the 18 Nm peak stall torque (17.5 A) handles short-duration acceleration and deceleration events. The single-turn SinCos Hiperface encoder provides absolute position within one revolution — no multi-turn tracking, so the system must home after any power loss where the load can rotate more than one turn. No holding brake is fitted, meaning vertical-axis loads require an external brake or rely on the drive's holding torque at standstill.
Torque, speed, and thermal limits for the application
Nominal torque varies with the drive model and supply voltage — 5.67 Nm with LXM52 at 115 V three-phase, down to 4.2 Nm with LXM62 at 480 V three-phase. The torque constant is 1.19 Nm/A at 120 °C copper temperature, and the back EMF constant is 78 V/krpm, meaning at 4000 rpm the motor generates 312 V back EMF that must stay within the drive's DC bus voltage range. Natural convection cooling limits the thermal envelope to the frame surface area and ambient — no forced-air fan to extend the duty cycle. The IP65 rating seals the motor body against dust and low-pressure water jets, suitable for washdown environments but not submersion. Maximum radial force on the shaft is speed-dependent: 990 N at 1000 rpm, dropping to 620 N at 4000 rpm. This governs belt-drive or overhung-load applications — the bearing life is directly tied to the radial load at the operating speed.
The motor uses an international standard flange with a 100 mm flange size, 95 mm centring collar diameter, and 3.5 mm centring collar depth. The shaft is 19 mm diameter with a parallel key, 40 mm shaft length, and 6 mm key width — standard for coupling to gearboxes or direct-drive loads. Rotatable right-angled connectors allow the cable exit orientation to be adjusted after mounting, simplifying routing in tight cabinets. The overall length is 160.6 mm (6.3 in) from the mounting face.
