The SH30702M02A1200: This SH3 frame servo delivers 640 W continuous power with a nominal speed of 3000 rpm at 400 V three-phase supply. At 480 V three-phase it reaches 3600 rpm, while single-phase 115 V drops to 750 rpm — the speed-torque envelope shifts with the input voltage, so the drive selection must match the actual line voltage to get the rated performance. Nominal torque sits at 2.03 N.m for both 400 V and 480 V three-phase operation, with a continuous stall torque of 2.04 N.m across the 115–480 V three-phase range. Peak stall torque hits 7.6 N.m — useful for short acceleration bursts or overcoming static friction on startup. The absolute multiturn SinCos Hiperface encoder retains position through power cycles, so the machine doesn't need a homing sequence after a power loss or controlled stop. That saves cycle time on multi-axis lines where every restart counts.
IP65/IP67 sealing and smooth shaft — deployment context
The motor body carries IP65 per IEC 60034-5, the shaft bushing is also IP65, and the housing is rated IP67. That means the motor withstands hose-down cleaning and occasional submersion — a fit for food processing, washdown stations, or outdoor conveyor sections where moisture gets into the motor envelope. Smooth shaft end and no holding brake — this variant is intended for applications where the load holds position through the drive's holding torque or an external brake. If the application needs a fail-safe brake on the motor shaft, this isn't the variant; the brake-less version keeps the package shorter and lighter. Mounting uses an international standard flange with 70 mm centring diameter and 60 mm centring collar, four M5 holes on a 5.5 mm diameter bolt circle. The 11 mm shaft with a 4 mm keyway and 23 mm shaft length mates with standard couplings and pulleys in the SH3 frame class.
Electrical interface and thermal limits
Connection options include a rotatable right-angled connector and a straight connector — both let the cable exit in the direction that fits the cable tray or drag chain layout. The encoder is a separate cable; the power and feedback paths stay isolated. Stator resistance is 16.4 Ω and inductance is 41.55 mH — these set the electrical time constant and influence the drive's current-loop tuning. 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. Maximum continuous stall current is 1.5 A; peak current for 3 seconds is 6.0 A. Cooling is natural convection — no fan, so the motor relies on its own surface area and the machine's airflow. The 130 °C copper hot-spot temperature is the thermal ceiling; in a confined enclosure or high-ambient environment, derate the duty cycle accordingly.
