What the SH31002P1BF4000 delivers
The SH31002P1BF4000 is a Schneider Electric SH3-series servo motor with an integrated holding brake, built for three-phase systems. It delivers 1930 W nominal output power at 400 V three-phase, with a nominal torque of 4.6 N.m at that voltage. The holding brake is the key differentiator here — it holds 9 N.m (79.7 lbf.in) when the motor is powered down, which means the load stays put on a vertical axis or when the drive is disabled. No external brake resistor or mechanical lock needed for holding duty. The absolute multiturn Hiperface DSL encoder feeds position and speed data back over a single cable, eliminating a separate feedback harness. That simplifies the cable chain on a moving axis and reduces the number of connection points that can fail on a packaging or material-handling line.
Speed and torque across supply voltages
Nominal speed depends on the supply: 2000 rpm on 230 V single-phase, 4000 rpm on 400 V three-phase, and 4800 rpm on 480 V three-phase. The torque constant is 1.21 N.m/A at 120 °C copper temperature, so the drive current scales predictably with the load. Peak stall torque hits 18.3 N.m across the 115–480 V three-phase range — that's the torque available for acceleration during a rapid move or to break away a stuck load. Continuous stall torque is 5.8 N.m over the same voltage band, which sets the thermal limit for holding a position under load without moving. Maximum current Irms is 17.1 A, and the 3-second peak output current matches that figure — the drive must be sized to supply this peak without tripping on overcurrent during acceleration transients.
Mounting and environmental fit
The motor flange is 100 mm (3.9 in) with an international standard flange pattern, and the shaft is 19 mm diameter with a parallel key and a 6 mm keyway. Overall length is 235.5 mm (9.3 in) — measure the available space on the machine frame before committing. IP65 on the motor body means it handles washdown and dust ingress on a food or packaging line. The shaft bushing is IP54 without the shaft seal ring — if the application sees direct spray on the shaft exit, add the seal ring to keep the rating consistent. Natural convection cooling — no fan, so no fan noise or debris ingestion. The thermal limit is set by the 130 °C copper hot-spot temperature; the motor relies on the machine frame and ambient airflow to shed heat. Mount it where air can move across the housing.
