660 W servo with 9 N.m holding brake — envelope and feedback
The SH31001M12F2000 is a three-phase servo motor from Schneider Electric's SH3 series, delivering 660 W continuous power and a nominal torque range of 2.52 to 2.8 N.m depending on supply voltage (115 V single-phase through 480 V three-phase). It includes a holding brake rated at 9 N.m, making it suitable for vertical-axis or gravity-loaded applications where the load must be held when power is removed. The motor is 199.5 mm long with a 100 mm flange and a 19 mm shaft with parallel key — standard dimensions that fit common servo mounts. Feedback comes from an absolute multiturn SinCos Hiperface encoder, which provides position and speed data without needing a homing cycle after power-up — critical for applications requiring absolute position retention.
Speed and torque profile across supply voltages
Nominal speed varies with supply: 625 rpm at 115 V single-phase, 1250 rpm at 230 V single-phase, 2500 rpm at 400 V three-phase, and 3000 rpm at 480 V three-phase — the motor's performance scales with available line voltage. Nominal torque also shifts: 2.8 N.m at 115 V single-phase, 2.71 N.m at 230 V single-phase, and 2.52 N.m at both 400 V and 480 V three-phase, so the torque curve is relatively flat across the voltage range. Peak stall torque reaches 9.6 N.m (115–480 V three-phase), and continuous stall torque is 2.94 N.m — useful for sizing the motor against peak load transients. The motor has 4 poles, a torque constant of 1.63 N.m/A at 120 °C, and a back EMF constant of 115 V/krpm at 20 °C.
Environmental sealing and cooling — IP65 with natural convection
IP65 protection (conforming to IEC 60034-5) on the motor body and shaft bushing means the motor withstands dust ingress and low-pressure water jets — typical for washdown or dusty environments. Cooling is by natural convection — no fan, so the motor relies on its surface area and mounting plate for heat dissipation; derating may be needed in enclosed or high-ambient installations. The electrical connection uses a rotatable right-angled connector, which helps route the cable in tight panels without bending the cable beyond its minimum radius. Maximum radial force at the shaft is 900 N at 1000 rpm, dropping to 530 N at 5000 rpm — pay attention to belt or direct-drive loads that apply side force at speed.
Sourcing and lifecycle — current production, quoted to order
No official successor or cross-reference is listed — the SH31001M12F2000 is the direct order code for this configuration.
