1190 W, 6000 rpm — SH3 servo motor without brake
The SH31001P1BA3100 is a three-phase SH3 servo motor from Schneider Electric, rated for 1190 W continuous power at 400 V or 480 V three-phase supply, and 690 W on 230 V single-phase. Nominal speed hits 2500 rpm on single-phase, 5000 rpm on 400 V three-phase, and 6000 rpm on 480 V three-phase. This variant ships without a holding brake, so the load must be held by the drive's dynamic braking or an external mechanical brake. The absolute multiturn Hiperface DSL encoder provides position feedback over a single cable — no separate encoder line needed, which simplifies the cable chain on moving axes.
Torque and speed across supply voltages
Nominal torque is 2.64 N.m on 230 V single-phase, dropping to 2.27 N.m on 400 V or 480 V three-phase. Peak stall torque reaches 9.6 N.m on 115–480 V three-phase, and continuous stall torque is 2.94 N.m across the same range. The motor's torque constant is 0.84 N.m/A at 120 °C copper temperature, and the back EMF constant is 60 V/krpm at 20 °C. Stator resistance is 3.8 Ohm, inductance 19 mH — these matter for the drive tuning loop, especially at the 6000 rpm ceiling.
IP65, natural convection, and mechanical limits
The motor body and shaft bushing both carry IP65 per IEC 60034-5, so it handles washdown and dust without an extra cover. Cooling is natural convection — no fan, so the ambient temperature and duty cycle govern the thermal budget. Maximum radial force at the shaft is 2240 N at 1000 rpm, dropping to 1550 N at 3000 rpm. Maximum axial force is 300 N. The shaft is 19 mm diameter with a parallel key, 40 mm length — standard for a 100 mm flange motor.
