Key ratings that govern the fit
The MH31402P11F2200: Three-phase winding — the motor is designed for a three-phase servo drive output; it will not run on a single-phase VFD without a phase converter. The continuous power rating of 3730 W (3.73 kW) sets the mechanical work ceiling for the driven load, and the nominal torque of 144.62 lbf·in (16.34 N·m) is what the motor delivers continuously at rated speed — this is the number to match against the load torque profile. Peak stall torque of 491.2 lbf·in (55.5 N·m) at 115–480 V three-phase gives the short-duration overload headroom for acceleration ramps and emergency stops. The holding brake (18 W pull-in power) locks the rotor when power is removed — essential for vertical-axis applications where the load must not drift on power loss.
Encoder, cooling, and environmental sealing
Single-turn SinCos Hiperface encoder provides high-resolution absolute position feedback within one revolution — no multi-turn count, so the controller knows the shaft angle on power-up but not the total number of turns. The motor is cooled by natural convection (no fan), so the mounting surface and ambient airflow must be adequate to keep the winding temperature below the 135 °C copper hot limit. IP65 standard means the motor body is sealed against dust ingress and low-pressure water jets — suitable for washdown environments in food processing or packaging lines, but not for submersion or high-pressure spray (IP66/IP67 would be needed for those).
Mechanical interface and shaft loading
International standard flange with a 140 mm (5.5 in) flange size and 130 mm centring collar — mounts to standard NEMA/IEC motor flanges without an adapter. The shaft is 24 mm diameter with a parallel key, 50 mm shaft length, and 8 mm key width. Maximum radial force at the shaft centre is 2240 N at 1000 rpm, derating to 1550 N at 3000 rpm — belt or pulley loads must stay within this envelope to avoid bearing damage. Rotatable right-angled connectors allow the cable exit orientation to be adjusted after the motor is bolted down — useful in tight cabinets where straight connectors would interfere with the enclosure wall or adjacent components.
