1900 W continuous, torque curve tied to supply voltage
The SH31002P12A1200 is a 1900 W continuous-rated servo motor from Schneider Electric's SH3 family, delivering 4.6 N.m nominal torque at 400 V three-phase supply. The torque varies with the input voltage: 5.5 N.m at 115 V single-phase, 5.2 N.m at 230 V single-phase, and 4.4 N.m at 480 V three-phase. This means the motor's torque rating is not a single figure — the available torque drops as line voltage rises, so the drive sizing calculation must use the voltage that matches the actual installation.
Absolute multiturn encoder, IP65 sealed construction
The encoder is an absolute multiturn SinCos Hiperface type — this gives position feedback on power-up without a homing cycle, and the SinCos interface transmits both position and speed data over a single cable pair. The motor carries IP65 protection on the housing and shaft bushing per IEC 60034-5, with IP67 on the housing only. That means it handles washdown spray on the body but the shaft seal is rated for splashing, not immersion. Electrical connection is through a rotatable right-angled connector or a straight connector — both are included as options, so the cable exit direction can be oriented to fit the machine envelope without an adapter. The motor flange is an international standard 100 mm (3.9 in) size with a 95 mm centring collar and 9 mm mounting holes, matching the common IEC frame pattern for this power class.
Peak torque and thermal limits for duty-cycle applications
The maximum current Irms is 17.1 A, with the same value for the 3-second peak output current. The stator resistance is 2.4 Ohm and inductance is 6.75 mH, giving an electrical time constant of about 2.8 ms — fast enough for current-loop bandwidths up to roughly 1 kHz in the drive. The torque constant is 1.21 N.m/A at 120 °C copper temperature, so the drive's current limit directly sets the available torque at high temperature.
