Speed and torque across the voltage range
The SH31001M12F1200: This SH3 frame servo motor delivers a speed profile that depends on the supply voltage — 625 rpm on 115 V single-phase, 1250 rpm on 230 V single-phase, 2500 rpm on 400 V three-phase, and 3000 rpm on 480 V three-phase. Nominal torque holds fairly flat across the range at 2.52 N·m for three-phase supplies, with a slight bump to 2.8 N·m on 115 V single-phase. The continuous stall torque is 2.94 N·m, and peak stall torque reaches 9.6 N·m for short bursts. The motor is rated for 660 W continuous power, with nominal output power varying from 210 W on 115 V single-phase up to 930 W on 480 V three-phase. That means if you're running it on a 480 V line, you get the full power density the frame can deliver.
Built-in holding brake and encoder feedback
Feedback comes from an absolute multiturn SinCos Hiperface encoder — single-cable solution for both power and feedback if you're using a compatible Lexium drive. The absolute multiturn means the drive knows the shaft position at power-up without a homing cycle, which saves time on multi-axis machines.
Mounting and environmental sealing
The motor uses an international standard flange with a 100 mm (3.9 in) square pattern and a 95 mm centring collar. Shaft is 19 mm diameter with a parallel key, 40 mm shaft length — standard IEC metric dimensions that fit most direct-coupled loads and gearboxes. IP65 on the motor body and shaft bushing, IP67 on the housing — conforming to IEC 60034-5. That means it handles washdown and dust ingress on packaging lines or food processing equipment, as long as the connector is properly mated. Maximum radial force is 900 N at 1000 rpm, derating to 530 N at 5000 rpm — important to check if you're belt-driving a high-inertia load. Maximum axial force is 160 N.
Electrical parameters and cooling
Stator resistance is 13.9 Ω per phase, stator inductance 34.7 mH — a relatively high inductance motor that runs smooth at low speeds with good current regulation. The torque constant is 1.63 N·m/A at 120 °C copper temperature, and the back EMF constant is 115 V/krpm at 20 °C. Maximum continuous current is 6.3 A RMS, with a 3-second peak of 6.3 A — the peak rating matches the continuous, so the thermal limit is the winding temperature, not the drive's current capability. Cooling is natural convection, so no external fan or coolant needed. The motor is a 4-pole design, which gives a good balance between torque density and speed range. Rated temperature rise is 130 °C on the copper windings.
Connector options and compliance
Electrical connection is available with either a rotatable right-angled connector or a straight connector — lets you route the cable in tight cabinets without a 90-degree adapter. The connector is IP65-rated when mated, so keep the sealing surfaces clean during installation.
