Speed-torque envelope and supply voltage dependency
The SH31001M01F1100 is a three-phase servo motor with an integrated holding brake, delivering a nominal speed that shifts with the 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. This means the same motor covers both low-speed high-torque and high-speed applications depending on the drive input — a single BOM line for multiple line voltages if the drive is configured accordingly. Nominal torque also derates with voltage: 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. The continuous stall torque is 2.94 N·m across the three-phase range, while peak stall torque reaches 9.6 N·m for short-duration acceleration or overcoming static friction. Continuous power output is 660 W, with nominal output power varying from 210 W at 115 V single-phase up to 930 W at 480 V three-phase. The motor uses natural convection cooling, so no forced-air clearance is needed in the cabinet — useful for compact panel layouts.
Holding brake and safety-critical vertical-axis loads
The integrated holding brake delivers 9 N·m of holding torque, which is the parameter that governs whether this motor can safely hold a vertical-axis load at rest without drifting. For a Z-axis or gravity-loaded application, the brake torque must exceed the load torque by the safety margin specified in the machine directive — typically 1.5× to 2×. The brake is included as standard, eliminating the need for an external brake resistor or mechanical lock.
Encoder feedback and IP rating for washdown environments
The encoder is an absolute single-turn SinCos Hiperface type, which provides position feedback at power-up without a homing cycle — critical for applications where the machine must resume operation after a power loss without re-referencing. The single-turn resolution is sufficient for applications that do not require multi-turn absolute position tracking. Both the motor body and the shaft bushing are rated IP65 per IEC 60034-5, meaning they withstand hose-directed water and dust ingress. This makes the motor suitable for food-and-beverage washdown lines or outdoor installations where the motor is exposed to rain or cleaning sprays — no additional enclosure needed for the motor itself.
Mechanical interface and mounting dimensions
The motor uses an international standard flange with a 100 mm flange size and a 95 mm centring collar diameter. The shaft is 19 mm diameter, 40 mm long, with a 6 mm keyway, and the shaft end is smooth — no threaded hole or special feature. Mounting holes are 9 mm diameter on a 3.7 in (95 mm) centring collar, with a centring collar depth of 3.5 mm. Overall length is 199.5 mm (7.9 in). The electrical connection is a straight connector — no right-angle or rotatable option, so plan the cable exit path accordingly in the cable tray or drag chain.
Electrical parameters and thermal limits
Stator resistance is 13.9 Ω and stator inductance is 34.7 mH — these values are used by the drive's autotuning routine to calculate the current loop gains. 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 RMS current is 6.3 A, with a 3-second peak current also rated at 6.3 A. The motor has 4 poles. Maximum radial force at the shaft is 900 N at 1000 rpm, derating to 530 N at 5000 rpm. Maximum axial force is 160 N. The hot-spot copper temperature limit is 130 °C — the drive's thermal model should be configured with this limit to prevent winding damage during overload cycles.
No pin-compatible or functional alternative within the same SH3 series is documented as a direct replacement. If a second-source or alternate is needed, the sizing reference SH31001M provides the parametric baseline for a cross-search within the Schneider Electric servo motor family.
