Motor envelope and mounting — 100 mm flange, 235.5 mm body
The SH31002M12F2200 uses an international standard flange with a 100 mm bolt circle and 95 mm centring collar, 3.5 mm deep. Overall body length is 235.5 mm — measure the available cavity before ordering, especially in retrofit cabinets where the old motor was shorter. Shaft is 19 mm diameter with a parallel key, 40 mm shaft length, 6 mm key width. The shaft bushing and housing both carry IP65 per IEC 60034-5; the housing alone is IP67 — this motor survives washdown if the cable connector is properly mated.
Speed-torque map across supply voltages
Nominal speed depends on the drive supply: 500 rpm at 115 V single-phase, 1000 rpm at 230 V single-phase, 2000 rpm at 400 V three-phase, and 2400 rpm at 480 V three-phase. Nominal torque drops slightly from 5.62 Nm at 115 V to 5.28 Nm at 400/480 V three-phase — the torque curve is flat across the voltage range, so the motor doesn't lose much grunt when you step up the line. Continuous stall torque is 5.8 Nm across the three-phase range (115 to 480 V). Peak stall torque hits 18.3 Nm — useful for breakaway or short overloads, but the 9.0 A peak current limit (3 s) governs how long you can hold that peak before the drive trips.
Brake and feedback — holding torque and encoder type
Feedback is an absolute multiturn SinCos Hiperface encoder. No homing sequence needed after power loss — the drive reads absolute position on power-up. Confirm the drive model supports Hiperface protocol; not all servo drives do.
Electrical parameters for drive tuning
Stator resistance is 8.6 Ω, inductance 24.3 mH — these set the current-loop tuning gains. Torque constant is 2.32 Nm/A at 120 °C copper temperature; back EMF constant is 146 V/krpm at 20 °C. The 4-pole motor (1500 rpm synchronous at 50 Hz) means the drive's velocity loop gains will differ from a 6- or 8-pole machine. Continuous power is 1100 W, but nominal output power varies with supply: 300 W at 115 V single-phase, 580 W at 230 V single-phase, 1090 W at 400 V three-phase, 1280 W at 480 V three-phase. The motor is naturally convection-cooled — no fan, so don't bury it in a tight enclosure without airflow.
