Speed-torque envelope by supply voltage
The SH31404P12F2200: This motor delivers 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 speed is supply-dependent, not a fixed rating. Nominal torque varies with the same supply: 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. The 115 V and 230 V single-phase curves deliver higher torque at lower speeds, suited for direct-drive applications without a gearbox. Peak stall torque reaches 131.9 N·m across the 115...480 V three-phase range, with a 3-second peak current of 95.6 A — this is the transient overload ceiling for acceleration or emergency stops.
Brake and encoder — what locks and what tracks
Holding brake torque is 36 N·m, sufficient to hold a vertical load on a Z-axis or gantry without power — the brake engages when the drive enable drops, not on a separate signal. The absolute multiturn SinCos Hiperface encoder provides position feedback without a home cycle after power loss — the multiturn count tracks shaft revolutions even unpowered, eliminating re-referencing on restart.
Mechanical fit and environmental sealing
Motor flange size is 140 mm (5.5 in) with a centring collar depth of 3.5 mm — mounts to standard IEC B5 or IM B5 flanges. Overall length is 420.5 mm (16.6 in), including the rotatable right-angled connector. IP65 on the motor body and shaft bushing, IP67 on the housing — the motor withstands washdown and temporary submersion when the connector is mated and the shaft seal is intact. Natural convection cooling means no external fan or compressed air is needed. Shaft diameter is 24 mm with a parallel key, key width 8 mm, shaft length 50 mm — standard for coupling to a load via a flexible jaw or bellows coupling.
Electrical parameters for drive tuning
Stator resistance is 0.28 Ω and stator inductance is 2.035 mH — these values set the current-loop bandwidth and the L/R time constant for the drive's auto-tuning routine. Torque constant is 1.57 N·m/A at 120 °C copper temperature; the back EMF constant is 104 V/krpm at 20 °C. These are the conversion factors between current and torque, and speed and voltage, respectively — used to calibrate the drive's torque and speed loops. Continuous power is 4040 W at 400 V three-phase, with nominal output power of 4190 W at 480 V three-phase — the motor is sized for a 4 kW class application with headroom at higher line voltages.
