What the SH3 frame delivers at 230 V single-phase
The Schneider Electric SH30402P1CF4000 is a servo motor from the SH3 family with an integrated holding brake, sized around a 40 mm flange and rated for 0.37 N.m nominal torque at 230 V single-phase — the headline figure for a panel builder picking the matching drive stage. At 230 V single-phase it holds 4000 rpm nominal; move to 400 V or 480 V three-phase and the shaft can run to 9000 rpm nominal with 0.31 N.m and 292 W continuous output power, so the same motor body covers single-phase machine builds and three-phase higher-speed lines without a re-spec. Peak stall torque reaches 1.5 N.m at 480 V three-phase, giving headroom over the 0.39 N.m continuous stall figure for short accel/decel bursts on indexing axes.
Brake, encoder, and the loop the drive sees
The integrated holding brake delivers 0.4 N.m at 5.8 W pull-in power — sized to hold the vertical axis at standstill without continuous duty, so the brake supply can be cut between moves to save cabinet heat. Feedback is an absolute single-turn Hiperface DSL encoder, the digital single-cable protocol used across the Schneider Lexium/Modicon servo drives — one cable carries power and feedback, which simplifies the cabinet entry on a small-footprint machine. Electrical constants for the drive's auto-tune pass: 11.6 Ohm stator resistance, 12.8 mH stator inductance, 0.26 N.m/A torque constant at 120 °C, and 18 V/krpm back-EMF constant at 20 °C — these are the values the commissioning tool reads back when the motor identifier is loaded.
Mechanical fit on the machine
Flange mounting follows the international standard pattern with a 40 mm motor flange, four 4.5 mm mounting holes, and a 30 mm centring collar 2.5 mm deep — drop-in replacement for an existing SH3 footprint in a rebuild. Shaft is 8 mm diameter with a 3 mm parallel key, 25 mm shaft length — the standard small-frame shaft so standard couplings and pinion gears from the SH3 accessory line fit without machining. Sealing is IP65 on the motor body with IP54 at the shaft bushing when no shaft seal is fitted — sealed enough for typical factory cabinet-side mounting where the shaft passes into a gearbox, not for direct washdown.
Thermal envelope and where the rating actually pins
Cooling is natural convection; continuous power is 290 W with copper-hot limit 130 °C, so derating starts above the ambient curve printed on the nameplate rather than at a fixed duty-cycle cap. Maximum mechanical speed is 10000 rpm and maximum RMS current is 7.2 A — the speed ceiling is the mechanical limit, well above the 9000 rpm nominal at three-phase, leaving margin for short overshoots in a position profile. The right-angle quicklock connector rotates to the cable entry direction during install, and the three-phase power network is the standard servo drive bus — match the drive-side connector family before the panel is wired.
Lifecycle and sourcing posture
Lifecycle status reads current on the manufacturer record, with the SH3 sizing reference SH30402P identifying the family — no PCN or last-time-buy notice on this order code, so the BOM line is stable and rebuilds can plan against standard Schneider lead times. Spec-thin on certifications — no UL, CE, REACH or RoHS line appears in the published record alongside this motor, so the declaration-of-conformity pack has to be pulled at quote time rather than read off the listing.
