1500 W servo — torque and speed across supply voltages
The SH31003M01A1200: Rated 1500 W continuous power, this SH3-series motor delivers 7.8 Nm nominal torque at 400 V three-phase, with nominal speed reaching 2000 rpm on that same supply. On 480 V three-phase, nominal torque drops slightly to 6.76 Nm while speed increases to 2400 rpm — the torque-speed envelope shifts with line voltage, so the drive's DC bus voltage sets the actual operating point. Peak stall torque is 28.3 Nm across the 115–480 V three-phase range, giving a 3.5× overload margin over the 8 Nm continuous stall torque. The 14.7 A peak current (3 s rating) matches the drive's short-term current capability — confirm the servo drive's peak current rating supports this transient draw.
Feedback and environmental sealing
Absolute single-turn SinCos Hiperface encoder provides position feedback without a home cycle on power-up — the single-turn resolution is set by the encoder's native count, and the Hiperface protocol carries both position and temperature data over the same cable pair. The motor body and shaft bushing are IP65-rated per IEC 60034-5, with the housing rated IP67; this suits washdown environments but the rotatable right-angle or straight connector must be properly seated to maintain the seal. Natural convection cooling means no fan — the 130 °C copper hot-spot temperature limits continuous duty in confined enclosures. The 17.4 mH stator inductance and 5.3 Ω resistance define the motor's electrical time constant; the drive's current loop tuning should account for these values.
Mounting and mechanical interface
International standard flange (100 mm square) with a 95 mm centring collar and 9 mm mounting holes — bolts through the flange face, not the housing. The 19 mm smooth shaft (no keyway) extends 40 mm; radial force limits drop from 1050 N at 1000 rpm to 660 N at 4000 rpm, so belt-driven loads need a bearing support if the overhung load exceeds the curve.
