Supply voltage defines the speed-torque envelope
The SH31003M02A2000: This SH3 servo motor delivers 1500 W continuous power, but the nominal speed and torque depend entirely on the supply voltage feeding the drive. At 115 V single phase you get 500 rpm and 7.8 Nm; at 480 V three phase the speed climbs to 2400 rpm while torque drops to 6.76 Nm. The peak stall torque across the 115...480 V three-phase range is 28.3 Nm — that's the short-term acceleration ceiling. The torque constant is 2.35 Nm/A at 120 °C copper temperature, and the continuous stall current is 3.4 A. The 3-second peak current is 14.7 A — the drive must be sized to deliver this for acceleration without tripping.
Encoder and feedback — no homing needed
The absolute multiturn SinCos Hiperface encoder means the drive knows the rotor position immediately on power-up — no homing sequence, no reference run. This saves cycle time on machines that power-cycle between shifts. The back EMF constant is 148 V/krpm at 20 °C — match this to the drive's DC bus voltage ceiling to avoid overvoltage at high speed.
Mounting and mechanical fit
The motor flange is 100 mm (3.9 in) with a 95 mm centring collar and 9 mm mounting holes — standard international flange pattern. The smooth shaft is 19 mm diameter, 40 mm long, with a 6 mm keyway. No holding brake is fitted, so the load must hold position without motor brake torque. The electrical connection is a rotatable right-angled connector — the cable exit direction can be adjusted after the motor is bolted down, which helps in tight cabinets. The IP rating is IP54 at the shaft bushing without the seal ring, and IP65 on the motor body and with the shaft seal fitted — washdown-ready for food or wet environments.
