Speed and torque across supply voltages
The SH31404P12F2000: This motor delivers different nominal speeds depending on the supply: 750 rpm on 115 V single-phase, 1500 rpm on 230 V single-phase, 3000 rpm on 400 V three-phase, and 3600 rpm on 480 V three-phase. The nominal torque also shifts with voltage — 30.2 N·m at 115 V single-phase, 26.3 N·m at 230 V single-phase, 12.9 N·m at 400 V three-phase, and 11.1 N·m at 480 V three-phase. That means the same motor frame covers both low-voltage single-phase and high-voltage three-phase lines, but the torque available at the shaft depends on which supply you wire it to. Continuous power is 4040 W at 400 V three-phase, with nominal output power ranging from 2370 W (115 V single-phase) up to 4190 W (480 V three-phase). The continuous stall torque across the three-phase range is 33.4 N·m, and peak stall torque hits 131.9 N·m — useful for acceleration transients in indexing or pick-and-place moves.
Brake and encoder — what locks and what tracks
The holding brake delivers 36 N·m of holding torque, enough to keep a vertical axis or a heavy payload from drifting when the drive is disabled. The brake is integral to the motor — no external brake resistor or separate power supply needed for the holding function. Feedback comes from an absolute multiturn SinCos Hiperface encoder. That means the drive knows the rotor position and the number of shaft revolutions on power-up without needing a homing sequence — the absolute position is retained across power cycles. This saves one home-prox sensor and the associated wiring on multi-axis machines.
Mounting and environmental fit
The motor uses an international standard flange with a 140 mm flange size and a 24 mm shaft diameter with a parallel key. The centring collar depth is 3.5 mm, and the mounting holes are 11 mm in diameter — standard for IEC frame-mount interfaces. IP rating is dual: IP54 at the shaft bushing without the shaft seal ring, and IP65 for the motor body and shaft bushing when the seal ring is fitted. For washdown or wet environments, specify the shaft seal ring to get IP65 at the rotating seal. Cooling is natural convection — no fan, so no fan noise or filter maintenance, but the thermal budget depends on the mounting surface and ambient airflow. The electrical connection uses a rotatable right-angled connector, which lets you orient the cable exit to clear adjacent hardware in a tight cabinet or cable tray.
Electrical parameters for drive tuning
Stator resistance is 0.28 ohm and stator inductance is 2.035 mH — these feed directly into the autotuning routine of a Schneider or third-party servo drive. The torque constant is 1.57 N·m/A at 120 °C copper temperature, and the back-EMF constant is 104 V/krpm at 20 °C. Maximum current Irms is 95.6 A, which sets the drive sizing floor for peak torque delivery. The motor has 5 pole pairs. Maximum radial force at the shaft is 2660 N at 1000 rpm, 2110 N at 2000 rpm, and 1840 N at 3000 rpm; maximum axial force is 300 N. These limits matter when coupling to a belt drive or a leadscrew — exceeding them wears the bearings prematurely.
