The nominal speed follows the same pattern: 750 rpm at 115 V single-phase, 1500 rpm at 230 V single-phase, 3000 rpm at 400 V three-phase, and 3600 rpm at 480 V three-phase. For a three-phase 400 V supply, the nominal output power is 3860 W, and continuous power is 3900 W — the slight difference reflects the stall-torque thermal limit. Peak stall torque is 60.1 N·m across the 115...480 V three-phase range, with a continuous stall torque of 19.5 N·m. The holding brake adds 23 N·m of holding torque — enough to secure a vertical axis without external braking resistors. The torque constant is 1.47 N·m/A at 120 °C winding temperature, so the 44.1 A peak current (3 s rating) corresponds to the 60.1 N·m peak torque. ## Mounting, sealing, and mechanical interface The motor flange is 140 mm (5.5 in) with an international standard pattern — four 11 mm mounting holes on a centring collar 3.5 mm deep. The shaft is 24 mm diameter by 50 mm long with a parallel key (8 mm key width). Overall length is 310.5 mm (12.2 in). The IP65 rating applies to the motor body and shaft bushing per IEC 60034-5; the housing is IP67 — suitable for washdown environments. Cooling is natural convection, so the motor relies on the mounting surface and ambient airflow for heat dissipation. Maximum radial force is 2240 N at 1000 rpm, 1780 N at 2000 rpm, and 1550 N at 3000 rpm — these limits guide belt-drive or overhung-load applications. Maximum axial force is 300 N. The straight connector electrical connection simplifies cable routing in tight panels. ## Feedback and electrical parameters for drive tuning The encoder is an absolute multiturn SinCos Hiperface type — no homing cycle needed after power loss; the drive reads the absolute position on startup. Stator resistance is 0.6 Ω, stator inductance is 3.855 mH, and the back EMF constant is 101 V/krpm at 20 °C. These values are needed for the drive's auto-tuning routine and for setting current-loop gains. The motor has 5 poles, which affects commutation and torque ripple.","metaTitle":"Schneider Electric SH31402P12F1200 Servo Motor with Brake","metaDescription":"Schneider Electric SH31402P12F1200 servo motor with holding brake.
