Speed and torque across the supply range
The SH31001M11A1000: This SH3 motor delivers different speed-torque curves depending on the supply. At 480 V three-phase it hits 3000 rpm nominal with 22.30 lbf·in (2.52 N·m) continuous torque; drop to 115 V single-phase and the nominal speed falls to 625 rpm with 24.8 lbf·in (2.8 N·m). The nominal output power climbs from 210 W at 115 V single-phase to 930 W at 480 V three-phase — spec the drive voltage before committing the motor to the BOM. Peak stall torque is 85.0 lbf·in (9.6 N·m) across the 115...480 V three-phase range — the motor can deliver short bursts well above the continuous rating for acceleration or emergency stops. Continuous stall torque sits at 26.02 lbf·in (2.94 N·m) across the same voltage band, giving a 3.3:1 peak-to-continuous ratio.
Encoder and feedback — absolute single-turn Hiperface
The SH31001M11A1000 carries an absolute single-turn SinCos Hiperface encoder. Single-turn means position is known within one revolution after power-up without a homing move — useful for pick-and-place or indexing axes where the travel is less than one revolution. The SinCos analog track gives interpolated position for smooth velocity control down to standstill. Hiperface is a standard protocol across Schneider and third-party drives. Verify the drive's Hiperface interface supports single-turn absolute mode — some older drives only handle multi-turn or incremental. The straight connector exit keeps the cable routing tight against the motor body, helpful in confined cabinets.
Mounting and cooling — no fan, standard flange
The motor mounts on a 100 mm international standard flange (3.9 in) with a 3.7 in centring collar and four 9 mm mounting holes. The 19 mm shaft with parallel key and 40 mm shaft length matches common coupling patterns for this frame size. Natural convection cooling means no external fan — the motor relies on air movement from the driven load or cabinet ventilation. Keep the ambient below 40 °C for full torque; derate above that per the motor's thermal model. IP rating depends on the shaft seal. The motor ships IP54 at the shaft bushing without a shaft seal ring; fit the seal ring and it reaches IP65. For washdown or dusty environments, specify the seal ring at order time — retrofitting it later requires disassembly. The motor body meets IP65 with the seal fitted.
Electrical parameters and thermal limits
Stator resistance is 13.9 Ω per phase with 99.15 mH inductance — a fairly high-impedance winding that limits current ripple. The continuous stall current is 1.8 A, with maximum Irms at 6.3 A. The torque constant is 1.63 N·m/A at 248 °F (120 °C), and the back-EMF constant is 115 V/krpm at 68 °F (20 °C). Use these to set the drive's current loop gains and velocity feed-forward.
