Speed-torque envelope across supply voltages
The SH31002M11A1000 delivers nominal torque of 5.28 Nm at 400 V three-phase and 2000 rpm, with the same torque figure at 480 V three-phase. On single-phase supply, nominal torque drops to 5.5 Nm at 230 V and 5.62 Nm at 115 V, while nominal speed falls to 1000 rpm and 500 rpm respectively. Continuous power is 1100 W, with peak stall torque reaching 18.3 Nm across the 115...480 V three-phase range. The continuous stall torque is 5.8 Nm, sustained by a continuous stall current of 2.5 A.
Feedback and electrical interface
The motor carries an absolute single-turn SinCos Hiperface encoder, providing position feedback without a battery-backed multi-turn count. Electrical connection is via a straight connector — no right-angle adapter needed for cable exit. Stator resistance is 8.6 Ohm with inductance 24.3 mH, giving a relatively high electrical time constant that the drive current loop must accommodate. The torque constant is 2.32 Nm/A at 120 °C, and the back EMF constant is 146 V/krpm at 20 °C — both needed for drive tuning and velocity-loop gain settings.
Mounting, sealing, and mechanical limits
The motor flange is 100 mm square (IEC standard), with a 95 mm centring collar and 3.5 mm collar depth. Four 9.0 mm mounting holes accept M8 bolts. The shaft is 19 mm diameter with a 6 mm parallel key and 40 mm shaft length. IP rating depends on the shaft seal configuration: IP54 with a bushing without shaft seal ring, or IP65 with the seal ring fitted. The motor body itself is rated IP65. Cooling is by natural convection — no external fan, so the thermal budget depends on the mounting surface and ambient airflow. Maximum radial force at the shaft is 990 N at 1000 rpm, derating to 620 N at 4000 rpm. Maximum axial force is 160 N. These limits govern coupling selection and belt-drive overhung loads.
