What this SH3 servo motor delivers on a machine
The SH31002M11F1200 is a 1.1 kW continuous-power servo motor from Schneider Electric's SH3 family, built for three-phase supply. It carries an integrated holding brake rated at 9 N.m — enough to hold a vertical axis stationary when power is removed, so no external brake resistor or mechanical lock is needed on the load side. The absolute single-turn SinCos Hiperface encoder gives position feedback at power-up without a homing cycle — the drive knows exactly where the shaft is the instant the bus comes up. That saves a reference move on every restart, which matters on machines that cycle power between batches or shifts.
Speed and torque across supply voltages
Nominal speed depends on the supply: 500 rpm at 115 V single-phase, 1000 rpm at 230 V single-phase, 2000 rpm at 400 V three-phase, and 2400 rpm at 480 V three-phase. The nominal torque also shifts — 5.62 N.m at 115 V single-phase, 5.5 N.m at 230 V single-phase, and 5.28 N.m at both 400 V and 480 V three-phase. That means the same motor delivers higher throughput on a 480 V line without re-winding. Peak stall torque is 18.3 N.m across the 115–480 V three-phase range, and continuous stall torque is 5.8 N.m. The torque constant is 2.32 N.m/A at 120 °C copper temperature, so the drive current limit can be set knowing the motor's hot-state output.
Mounting and environmental sealing
The motor uses a 100 mm international standard flange with a 95 mm centring collar and 9 mm mounting holes. Overall length is 235.5 mm, and the shaft is 19 mm diameter with a parallel key and 40 mm shaft length. The rotatable right-angle connector lets the cable exit in the direction that best fits the cable tray — no need for a separate right-angle adapter. IP65 on the motor body and shaft bushing, IP67 on the housing — conforming to IEC 60034-5. That means the motor handles washdown spray without a cover boot, suitable for food processing or packaging lines where hose-down cleaning is routine.
No official successor or cross-reference is listed for this order code. The SH3 family is the active series; the sizing reference SH31002M identifies the frame and winding variant.
