Mounting and form factor — 140 mm flange, straight connector
The SH31401P12F1100 uses an international standard flange with a 5.5 in (140 mm) mounting pattern and a 5.1 in (130 mm) centring collar, 0.1 in (3.5 mm) deep. Four mounting holes at 0.4 in (11 mm) diameter — the bolt circle matches the common IEC frame size for this power class. The shaft is 0.9 in (24 mm) diameter, 2.0 in (50 mm) long, with a parallel key and 0.3 in (8 mm) keyway. Overall body length is 10.06 in (255.5 mm). The electrical connection is a straight connector — no right-angle adapter needed, which simplifies cable routing in tight cabinets. IP65 protection on both the motor body and the shaft bushing per IEC 60034-5 means this motor handles washdown and airborne particulates without an additional cover — something to confirm if the application sees direct spray at the seal face.
Torque and speed profile across supply voltages
This is a multi-voltage motor — it delivers different nominal speeds depending on the supply: 750 rpm at 115 V single-phase, 1500 rpm at 230 V single-phase, 3000 rpm at 400 V three-phase, and 3600 rpm at 480 V three-phase. That range means the same frame can serve a 50 Hz line or a 60 Hz line without a motor swap. Nominal torque varies with voltage too: 10.95 N.m at 115 V single-phase, 10.6 N.m at 230 V single-phase, 9.2 N.m at 400 V three-phase, and 8.4 N.m at 480 V three-phase. Continuous stall torque is 11.1 N.m across the three-phase range. Peak stall torque reaches 27 N.m — useful for short-duration acceleration events. Continuous power is 2900 W, with nominal output power ranging from 860 W (115 V single-phase) up to 3170 W (480 V three-phase). The torque constant is 1.43 N.m/A at 120 °C copper temperature — a figure to use when sizing the drive current loop.
Encoder, brake, and feedback — what the absolute multitap means
The encoder is an absolute multiturn SinCos Hiperface type — it reports both position within one revolution and the total revolution count, so the drive knows the shaft position immediately on power-up without a homing routine. This saves cycle time on machines that power-cycle between batches. The holding brake delivers 23 N.m holding torque — enough to hold a vertical-axis load at rest when power is removed. The motor is listed with the brake included, so no separate brake resistor or external holding circuit is needed for the hold function.
Electrical parameters for drive sizing
Stator resistance is 1.41 Ohm and inductance is 23.72 mH — these set the electrical time constant and influence the drive's current regulator tuning. Maximum RMS current is 20.8 A; continuous stall current is 7.8 A. The drive must be rated to supply at least the peak current during acceleration. Back EMF constant is 100 V/krpm at 20 °C. This determines the bus voltage needed to reach a given speed — at 3600 rpm the back EMF is 360 V, so a 480 V bus has headroom for current regulation. Cooling is natural convection — no forced air or liquid cooling. The motor relies on its own surface area and the ambient airflow. In a confined cabinet or at low speeds with high continuous torque, check that the ambient stays within the copper temperature limit of 130 °C.
No stock-holding claim is made here — each RFQ is handled individually. If a second-source or replacement is needed, the sizing reference SH31401P points to the same frame family, but the specific encoder and brake configuration should be matched against the application requirements.
