Motor sizing and speed-torque across supply voltages
The SH31403P11A1200 delivers 4100 W continuous power, but the speed and torque available depend on the supply voltage feeding the drive. At 400 V three-phase, nominal speed is 3000 rpm with 12.9 N.m of torque; at 480 V three-phase, speed climbs to 3600 rpm but torque drops to 9.1 N.m. On single-phase 230 V, you get 1500 rpm at 21.2 N.m, and on 115 V single-phase, 750 rpm at 24.7 N.m. Continuous stall torque is 27.8 N.m across the 115...480 V three-phase range, and peak stall torque hits 90.2 N.m — that's the short-term overload headroom for acceleration or overcoming a stuck load.
Encoder feedback and environmental sealing
The absolute single-turn SinCos Hiperface encoder gives position feedback without needing a battery-backed multi-turn count — useful for applications that home on power-up and don't track absolute position over multiple revolutions. The straight connector mates to a standard Hiperface cable set. IP65 on the motor body and shaft bushing, IP67 on the housing per IEC 60034-5 — this motor handles washdown and wet environments, though the shaft seal is the wear item in continuous spray. Natural convection cooling means no fan to fail, but the thermal budget relies on the motor's surface area and mounting flange heat path.
Mechanical interface and load capacity
The 140 mm flange (5.5 in) with a 130 mm centring collar and 11 mm mounting holes fits the standard IEC B5 pattern. The 24 mm shaft with a parallel key and 50 mm shaft length couples to most common servo gearboxes and pulleys. Maximum radial force at the shaft is 2420 N at 1000 rpm, derating to 1670 N at 3000 rpm; axial force limit is 300 N.
Electrical parameters for drive tuning
Stator resistance is 0.4 Ohm and inductance is 2.66 mH — these set the electrical time constant and influence the drive's current-loop gains. The torque constant is 1.58 N.m/A at 120 °C copper temperature, and the back EMF constant is 105 V/krpm at 20 °C. Maximum RMS current is 61.0 A, which is also the 3-second peak current rating. The motor has 5 poles — this is an odd pole count, so confirm the drive's pole-pair setting is 2.5 (or 5 poles, depending on the drive parameter format). Copper hot temperature is 130 °C, which is the winding temperature limit under continuous rated load.
