What this SH3 servo motor delivers
The SH31401M02F2200 is a 1700 W continuous-power servo motor from Schneider Electric's SH3 series, fitted with a holding brake and an absolute multiturn SinCos Hiperface encoder. The brake holds 23 N.m static torque, which means the motor holds its position on a vertical axis without a separate mechanical lock. Nominal torque varies with supply: 11 N.m at 115 V single phase, 10.95 N.m at 230 V single phase, 10.6 N.m at 400 V three phase, and 10.4 N.m at 480 V three phase. The peak stall torque hits 27 N.m across the three-phase range, so the motor can deliver a short burst for acceleration or overcoming a jam. Speed also depends on the line voltage: 375 rpm at 115 V single phase, 750 rpm at 230 V single phase, 1500 rpm at 400 V three phase, and 1800 rpm at 480 V three phase. Maximum mechanical speed is 4000 rpm, so the motor can run above the nominal speed if the drive and load allow.
Encoder and feedback for position loops
The absolute multiturn SinCos Hiperface encoder gives position feedback without a home cycle after power loss — the multiturn count is retained. This matters for applications like pick-and-place or gantry axes where the controller needs absolute position on restart. The back EMF constant is 193 V/krpm at 20 °C, and the torque constant is 2.78 N.m/A at 120 °C copper temperature. These numbers let the drive calculate the motor's voltage and current demand across the speed range.
Mounting and environmental sealing
The motor uses an international standard flange with a 140 mm flange size and a 130 mm centring collar. The shaft is smooth, 24 mm diameter, 50 mm long, with an 8 mm keyway. Mounting holes are 11 mm diameter. IP65 on the motor and shaft bushing, IP67 on the housing — conforming to IEC 60034-5. That means the motor body can handle hose-down cleaning and the shaft seal resists water ingress, suitable for food processing or washdown zones.
