640 W SH3 servo — speed and torque across supply voltages
The SH30702M12A2000 is a Schneider Electric SH3 series servo motor rated for 640 W continuous power, with a nominal speed that shifts depending on the supply: 750 rpm on 115 V single-phase, 1500 rpm on 230 V single-phase, 3000 rpm on 400 V three-phase, and 3600 rpm on 480 V three-phase. Nominal torque also varies by supply — 2.2 N.m at 115 V single-phase, 2.15 N.m at 230 V single-phase, and 2.03 N.m at both 400 V and 480 V three-phase — so the motor delivers consistent torque across a wide voltage range, with only a small drop at higher line voltages. Peak stall torque reaches 7.6 N.m across the 115...480 V three-phase range, and continuous stall torque is 2.04 N.m, giving a peak-to-continuous ratio of about 3.7:1 for short-duration overloads.
Absolute multiturn Hiperface encoder — position feedback without homing
The encoder is an absolute multiturn SinCos Hiperface type, meaning the drive knows the motor shaft position at power-up without needing a homing sequence — critical for applications where the machine must resume from a known position after a power cycle. Natural convection cooling means no fan noise or forced-air dependency, but the thermal limit is set by the copper hot-spot temperature of 130 °C — the continuous stall current of 1.5 A and maximum continuous current of 6.0 A define the thermal operating envelope.
Mounting and mechanical interface — IEC flange, parallel key shaft
Mounting uses an international standard flange with a 70 mm flange size and 60 mm centring collar diameter, fitting standard IEC frame patterns for servo motors in this power class. The shaft is 11 mm diameter with a parallel key, 23 mm shaft length, and 4 mm key width — a common interface for coupling to ball screws, timing belts, or direct loads. Electrical connection options include a straight connector or a rotatable right-angled connector, giving flexibility for cable routing in confined cabinets.
IP protection and environmental limits
The IP rating depends on the shaft seal configuration: IP54 at the shaft bushing without a shaft seal ring, and IP65 for the motor body and shaft bushing when the seal ring is fitted — both conforming to IEC 60034-5. Maximum radial force on the shaft drops with speed: 710 N at 1000 rpm down to 390 N at 6000 rpm, and maximum axial force is 80 N — these limits must be respected to avoid bearing damage. The torque constant is 1.36 N.m/A at 120 °C copper temperature, and the back EMF constant is 95.9 V/krpm at 20 °C — useful for matching the motor to the drive's voltage and current limits.
Sourcing and lifecycle — current production, quoted to order
No official successor or cross-reference is recorded — the SH30702M12A2000 is the active variant for this frame size and encoder type.
