40 mm flange, single-cable DSL feedback, with holding brake
The SH30402P1DF4000: The part is a Schneider Electric SH3 servo motor in the 40 mm flange size, sized to reference SH30402P, with an integrated holding brake and an absolute multiturn Hiperface DSL encoder that collapses power and feedback onto a single quick-lock rotatable right-angle connector. It is built for the panel-side flange mount on the international standard footprint with four 4.5 mm mounting holes on a 30 mm centring collar, so it drops into a standard NEMA-style or IEC-matching machine frame without adapter hardware.
Speed, torque, and power envelope across the supply range
Rated nominal speed is 4000 rpm at 230 V single phase and 9000 rpm at both 400 V and 480 V three phase, with nominal torque of 0.37 N.m on 230 V single phase and 0.31 N.m on 400/480 V three phase — the three-phase figures put roughly 85 percent of the single-phase torque on the table at nearly 2.25× the shaft speed. Nominal output power is 152 W at 230 V single phase and 292 W at both 400 V and 480 V three phase, against a continuous power rating of 290 W — the 230 V single-phase operating point is thermally the tightest of the three. Peak stall torque reaches 1.5 N.m at 480 V three phase against a continuous stall torque of 0.39 N.m over 115...480 V three phase, so the motor can deliver roughly 3.8× its continuous figure for short acceleration pulses before the winding thermal limit binds. Maximum mechanical speed is 10000 rpm and maximum current Irms is 7.2 A against a continuous stall current of 1.5 A — the same roughly 4.8× ratio between peak and continuous shows up on the electrical side as on the torque side, which is what lets the drive accelerate the inertia load without tripping.
Brake, rotor inertia, and winding constants for sizing
Stator resistance is 11.6 Ohm and stator inductance is 12.8 mH, with a torque constant of 0.26 N.m/A at 120 °C and a back-EMF constant of 18 V/krpm at 20 °C — these four figures are what the drive's auto-tune routine leans on to land the current loop and the field-weakening boundary at the actual operating temperature. Cooling is natural convection only, with a copper hot-spot temperature limit of 130 °C — there is no forced-air fan variant in this SKU, so cabinet air movement around the body sets the derating ceiling at higher duty cycles.
Shaft, seals, and where it sits in the cabinet
Shaft diameter is 8 mm with a 25 mm shaft length and a 3 mm parallel key, giving a standard parallel-key coupling interface for a gearbox or pinion — the shaft bushing carries IP54 while the motor body itself meets IP65 per IEC 60034-5, which is enough for a washdown-adjacent machine when the shaft seal ring is added but not for direct food-zone splash.
