SH30402P0DF4100 — what the device actually is
The SH30402P0DF4100 is a Schneider Electric SH3 series servo motor with an integrated holding brake, sized as a 40 mm flange (SH30402P) device in the servo motor product family. It carries the SH30402P sizing reference under the SH3 short name and ships as a 3-phase brushless servo designed to sit on the Lexium drive platform via its quicklock right-angle connector. Continuous output is 290 W with 292 W available at 400 V and 480 V three-phase, and nominal torque reaches 0.37 N.m at 230 V single phase or 0.31 N.m at 400 V and 480 V three phase. That ceiling is what an integrator sizes the gearbox and load inertia against — not the higher single-phase figure, which is a 230 V operating point rather than a separate rating class.
Speed, stall, and peak torque — what the curves look like
Nominal speed is 4000 rpm at 230 V single phase and climbs to 9000 rpm at both 400 V and 480 V three phase, with a mechanical ceiling of 10000 rpm. Above that point bearing damage rather than commutation becomes the limiter, so any application pushing past 9000 rpm needs to clear the headroom margin with the drive's field-weakening map. Continuous stall torque sits at 0.39 N.m across the full 115 V to 480 V three-phase window, with continuous stall current of 1.5 A and a maximum Irms of 7.2 A. Peak stall torque reaches 1.5 N.m at 480 V three phase — roughly a 4× overload margin over the continuous figure — and that ratio is the dynamic envelope the drive's current limit has to clear for short accelerations.
Feedback, shaft, and brake — the mechanical interface
Feedback is an Absolute multiturn Hiperface DSL encoder with 32768 points per turn resolved over 4096 turns — a single-cable digital protocol that carries power and data on the same quicklock connector, so the cabinet side only routes one cable per axis. The shaft end is a smooth 8 mm diameter, 25 mm long stub with a 30 mm centring collar 2.5 mm deep, the geometry the coupling or pinion has to mate against. The integrated holding brake delivers 0.4 N.m of holding torque at 5.8 W pull-in power — sized as a static-locking brake for vertical-axis and gravity-loaded stops rather than a dynamic braking element. For emergency-stop energy dissipation the drive's braking resistor on the DC bus does the real work; the brake here only locks the shaft once rotation has stopped.
Mounting and thermal envelope
Cooling is natural convection only — no integrated fan — with a copper-hot temperature ceiling of 130 °C and IP65 sealing on both the motor body and the shaft bushing per IEC 60034-5. That combination supports washdown and dusty plant environments but caps continuous torque below what a force-ventilated SH3 variant would deliver in the same frame size; if the duty cycle sits above the S3 curve, the derating has to be budgeted into the sizing.
Motor electrical constants the drive sees
Stator resistance is 11.6 Ohm with 12.8 mH of inductance across the winding, and the torque constant is 0.26 N.m/A at 120 °C. The Kt figure drifts with temperature because copper losses warm the winding, so the drive's auto-tuning routine has to thermal-compensate or the torque accuracy at the shaft drops as the motor heats under load.
