The shaft side is a smooth (non-keyed) 9 mm journal running 20 mm out of the housing, and feedback is an absolute single-turn Hiperface DSL encoder read over the single-cable quicklock connector — there is no separate resolver or second feedback cable to land at the drive. ## Speed, torque, and power envelope across the supply range Nominal speed scales with the DC bus the drive presents: 4000 rpm on a single-phase 230 V supply, 8000 rpm on a three-phase 400 V bus, and 9000 rpm on a three-phase 480 V bus. The motor's 9000 rpm mechanical ceiling is therefore reached only on 480 V three-phase, and that is the working point the rest of the rating table is anchored to. Continuous output is 290 W on both 400 V and 480 V three-phase, dropping to 160 W on 230 V single-phase where the lower bus voltage limits the constant-power region. Nominal torque follows the same pattern: 0.5 N.m at 230 V single-phase versus 0.35 N.m at 400 V and 480 V three-phase — the higher speed on the three-phase rails trades torque for power at the same current envelope. Continuous stall torque is 0.42 N.m across the full 115 to 480 V three-phase range, with peak stall torque 1.5 N.m — roughly 3.6× the continuous figure — for acceleration and trip-recovery transients. The continuous stall current of 0.73 A scales to a 3-second peak of 2.9 A, which is also the Irms ceiling the drive must deliver for short bursts. ## Electrical constants the drive commissioning has to match Torque constant is 0.58 N.m/A at a 120 °C winding, with a back-EMF constant of 40 V/krpm at 20 °C — the two figures track each other and let the drive's current loop be sized directly from the requested torque. Stator resistance is 41.8 Ohm and inductance 37.13 mH on a 3-pole winding; the L/R ratio sets the achievable current-loop bandwidth before the drive runs out of voltage headroom. Winding hot-spot is rated to 130 °C and cooling is natural convection — no fan, no liquid, no external blower to specify or fail. The motor body and shaft bushing both meet IP65 to IEC 60034-5, which covers dust-ingress protection and jet-wash tolerance on a packaging or food-adjacent line; the shaft seal is what keeps washdown fluid out of the bearing cavity. ## Mechanical envelope and shaft-side load budget Radial shaft load is rated to 340 N at 1000 rpm, derating as speed rises, and maximum axial force is 40 N — coupling selection (rigid bellows, elastomer spider, or timing-belt idler) has to stay inside both envelopes, with the radial figure usually the binding constraint on belt-driven axes. ## Sourcing posture for the BOM line Lifecycle status is recorded as current production on the manufacturer's product record, so this part number remains a qualified slot on an existing BOM rather than a re-engineering exercise. The cable-end quicklock connector and the single-cable Hiperface DSL feedback mean no separate encoder cable has to be added to the BOM for the drive-end mating half.","metaTitle":"Schneider SH30551P0AA4100 Servo Motor, 55 mm, 0.5 N.m","metaDescription":"Schneider Electric SH30551P0AA4100 SH3 servo motor, 55 mm flange, 0.5 N.m nominal torque, Hiperface DSL feedback.
