640 W servo with integrated holding brake
The SH30702M02F1200 is a three-phase servo motor from the Schneider Electric SH3 family, delivering 640 W continuous power with a nominal torque profile that varies by supply voltage: 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 supplies. An integrated holding brake provides 3 N·m of holding torque, which keeps the load locked in position when the drive is powered down — essential for vertical-axis applications where the load must not drift during a power loss or E-stop. The absolute multiturn SinCos Hiperface encoder eliminates the need for a home-find sequence on power-up; the drive knows the exact shaft position and number of revolutions from the moment the bus voltage comes up, cutting cycle time on machines that power-cycle between batches.
Speed and torque across the voltage range
Nominal speed depends on 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 — the motor is wound to deliver rated torque across a wide voltage window, so the same part number can be used on 400 V European lines and 480 V North American lines without a rewind. Peak stall torque reaches 7.6 N·m across the 115–480 V three-phase range, giving a 3.7× overload margin above the continuous stall torque of 2.04 N·m — enough headroom for acceleration transients in pick-and-place or indexing applications without tripping the drive's current limit. Maximum mechanical speed is 8000 rpm, well above the nominal speed at any voltage, so the motor can be over-sped for rapid-traverse moves as long as the drive's velocity loop is tuned to stay within the bearing and rotor limits.
Mounting, cooling, and environmental sealing
The motor mounts on an international standard flange with a 70 mm square pilot and 60 mm centring collar — a common IEC frame size that fits standard gearbox input flanges without an adapter plate. Cooling is by natural convection only — no external fan or forced air required — which simplifies installation in clean-room or dust-sensitive environments but means the continuous torque rating assumes free airflow around the housing; derate if the motor is enclosed in a tight shroud. IP65 on the motor body and shaft bushing, with IP67 on the housing — the motor withstands washdown sprays and hose-directed water, making it suitable for food-processing or washdown zones where a standard IP54 servo would fail the seal.
Electrical interface and connector options
The motor ships with both a rotatable right-angled connector and a straight connector option, giving the installer flexibility to route the power and feedback cable in tight cable-tray bends or against a panel wall without stressing the connector body. Stator resistance is 16.4 Ω and inductance is 115.7 mH — these values matter for the drive's current-loop tuning; the drive autotune routine should be run on first commissioning to measure the actual winding parameters and compensate for cable length. 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 — these are the numbers the drive uses to calculate the motor's electrical angle and to set the current limit for the target torque.
