830 W servo motor for multi-voltage lines
The SH30703M11A1200 is a Schneider Electric SH3 series servo motor rated for 830 W continuous power, with a nominal speed that shifts with the supply: 750 rpm at 115 V single phase, 1500 rpm at 230 V single phase, 3000 rpm at 400 V three phase, and 3600 rpm at 480 V three phase. It delivers a nominal torque of 3.05 N.m at 115 V single phase, dropping to 2.63 N.m at 400 V three phase, and a peak stall torque of 11.3 N.m across the three-phase range — useful for acceleration transients in indexing or pick-and-place cells.
Encoder feedback and environmental sealing
Feedback comes from an absolute single-turn SinCos Hiperface encoder — a standard interface for Schneider drives and many third-party servo drives; confirm the drive's encoder port supports Hiperface before mating. The motor body carries IP65 protection, the shaft bushing is IP65, and the housing is IP67 per IEC 60034-5, making it suitable for washdown zones or dusty environments where coolant mist or fine particulates are present. Cooling is natural convection (no fan), so the thermal budget depends on the mounting surface and ambient air movement — derate if enclosed in a non-ventilated cavity.
Mounting and mechanical interface
The motor uses an international standard flange with a 70 mm flange size and a 60 mm centring collar, matching common gearbox input flanges in the NEMA 56 frame class. The shaft is 14 mm diameter with a parallel key, 30 mm shaft length, and 5 mm key width — standard for direct coupling to pulleys or gearbox bores.
Electrical parameters and drive sizing
Stator resistance is 10.7 Ohm and stator inductance is 27.65 mH — these values set the electrical time constant and influence the drive's current-loop tuning. Continuous stall current is 2.1 A, with a peak output current of 8.7 A for 3 seconds — the drive must be sized to supply the peak current during acceleration without tripping. The torque constant is 1.4 N.m/A at 120 °C copper temperature, and the back EMF constant is 95 V/krpm at 20 °C — these are needed for the drive's autotune and for calculating the bus voltage margin at high speed.
The electrical connection options include a rotatable right-angled connector and a straight connector — specify the cable exit orientation when ordering to fit the cabinet layout. No pin-compatible alternative is listed in the same family; the SH30703M11A1200 is the specific variant with the 830 W rating, Hiperface encoder, and no brake.
