1700 W servo with holding brake — SH3 frame
The SH31401M02F2100 is a Schneider Electric SH3 series servo motor with an integral holding brake, rated for 1700 W continuous power on three-phase supply. The 140 mm flange and 24 mm smooth shaft with a 50 mm shaft length suit it for direct coupling to ball screws or belt drives in positioning axes. Nominal speed depends on the supply 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. The maximum mechanical speed is 4000 rpm, so the motor can run above nominal when the load and drive allow.
Torque and brake — sizing for vertical loads
Holding torque is 23 N.m (203.6 lbf.in) — this is the brake's static capacity, enough to hold a vertical axis at rest without power. Nominal torque ranges from 10.4 N.m to 11 N.m depending on supply voltage and phase configuration, with continuous stall torque at 11.1 N.m across the three-phase range. Peak stall torque reaches 27 N.m (239.0 lbf.in) on three-phase supply, giving headroom for acceleration transients. The torque constant is 2.78 N.m/A at 120 °C copper temperature, which helps the drive tune current loops for consistent torque output.
Encoder and feedback — absolute multiturn Hiperface
The motor carries an absolute multiturn SinCos Hiperface encoder — this provides position feedback without a home cycle after power loss, critical for multi-axis gantries or tool changers. The Hiperface protocol is supported by most Schneider drives and many third-party servo drives with the proper interface card. Electrical connection uses a rotatable right-angled connector, which eases cable routing in tight cabinets. The IP65 rating on both the motor body and shaft bushing means it withstands washdown environments — food processing or packaging lines where hose-down cleaning is routine.
