Torque and power across supply voltages
The SH32052P11A1100: This SH3 servo motor delivers 7900 W continuous power, but the nominal torque and speed are supply-voltage dependent. On three-phase 400 V it produces 337.2 lbf·in (38.1 N·m) at 2000 rpm; on 480 V three-phase, 251.4 lbf·in (28.4 N·m) at 2400 rpm. The peak stall torque reaches 1947.2 lbf·in (220 N·m) across the 115...480 V three-phase range — that is the short-term overload ceiling for acceleration or emergency stops. The continuous stall torque is 574.4 lbf·in (64.9 N·m) on three-phase supply, meaning the motor can hold that torque indefinitely at zero speed without overheating — critical for tensioning or clamping applications.
Encoder feedback and electrical interface
The motor carries an absolute single-turn SinCos Hiperface encoder. This gives position feedback on power-up without a homing cycle — a time-saver on multi-axis machines where the controller supports Hiperface. The electrical connection uses a rotatable right-angled connector or a straight connector, giving flexibility in cable exit orientation on a crowded machine frame. Stator resistance is 0.3 Ohm and inductance is 2.95 mH. The torque constant is 2.52 N·m/A at 248 °F (120 °C) copper temperature, and the back EMF constant is 161 V/krpm at 68 °F (20 °C). These numbers feed the drive tuning parameters — the current loop gains scale from the stator time constant (L/R ≈ 9.8 ms).
Mounting and environmental sealing
The motor mounts to an international standard flange (IEC 60034-5) with a flange size of 8.07 in (205 mm) and a centring collar diameter of 7.09 in (180 mm). The shaft is 1.5 in (38 mm) diameter with a parallel key and a key width of 0.4 in (10 mm). The overall length is 15.9 in (405 mm). IP65 protection on both the motor body and the shaft bushing per IEC 60034-5 means it handles washdown and airborne dust — suitable for food processing, packaging, or outdoor machine-tool environments. Cooling is by natural convection, so no external fan or coolant circuit is needed, but the thermal budget depends on the mounting surface and ambient air movement.
