Motor sizing and voltage-dependent performance
The SH31402P01F2100 delivers 3.9 kW continuous power, but the nominal speed and torque shift with the supply voltage — a key consideration when the line voltage varies across sites. At 400 V three-phase, nominal speed is 3000 rpm with 12.3 N.m nominal torque; at 480 V three-phase, speed rises to 3600 rpm while torque drops to 9.7 N.m. The continuous stall torque across the 115–480 V three-phase range is 19.5 N.m.
Encoder feedback and integration constraints
The absolute single-turn SinCos Hiperface encoder provides position feedback without a homing sequence on power-up — the drive reads the absolute position within one revolution. For multi-turn applications, the drive must track turns externally. The rotatable right-angled connector lets the cable exit direction be adjusted on-site, which simplifies routing in tight cabinets or on moving gantries. The IP65 rating on both the motor body and shaft bushing means the motor withstands washdown — suitable for food-and-bev or wet machining lines. Natural convection cooling means no fan noise or filter maintenance, but the thermal budget depends on the mounting surface and ambient air movement — derate the continuous torque if the motor is enclosed or stacked.
Electrical parameters for drive tuning
Stator resistance is 0.6 Ohm and stator inductance is 3.855 mH — these values feed the drive's auto-tuning routine for current-loop gains and field-weakening thresholds. The torque constant is 1.47 N.m/A at 120 °C copper temperature. Back EMF constant is 101 V/krpm at 20 °C, which sets the voltage ceiling at high speed — at 3600 rpm the back EMF reaches about 364 V line-to-line, leaving headroom for a 480 V bus. Maximum continuous current is 44.1 A RMS; the 3-second peak current is also 44.1 A, so the peak torque is thermally limited by the motor's thermal time constant, not the drive's current limit.
Mechanical interface and load limits
The motor mounts on an international standard flange with a 140 mm (5.5 in) flange size and a 130 mm centring collar. The smooth shaft is 24 mm diameter by 50 mm long — no keyway, so the coupling must grip the shaft via a clamping or friction-fit hub. Maximum radial force is 2240 N at 1000 rpm, derating to 1550 N at 3000 rpm. Maximum axial force is 300 N. These limits govern the belt tension or gearbox overhung load — exceeding them shortens bearing life.
Sourcing and lifecycle status
No official successor or pin-compatible alternative is listed by Schneider Electric for the SH31402P01F2100. The sizing reference SH31402P indicates the motor frame and winding family; any substitution would require a full parametric review of torque, speed, inertia, and encoder type.
