Brake, encoder, and the single-cable hookup
The SH30551P1BF4000: Holding torque comes from an integral brake rated 0.8 N.m with a 10 W pull-in coil, so the shaft stays put on de-energise without a separate 24 V brake supply converter — useful when the axis must hold position with the bus down. Position feedback is an absolute multiturn Hiperface DSL encoder on a quicklock rotatable right-angled connector, meaning the motor runs on the Lexium drive's single-cable hybrid link rather than a separate resolver + power pair — the SH3 ships set up for that one-cable topology out of the box.
Speed and torque across the three supply rails
Nominal torque shifts with supply: 0.5 N.m at 230 V single phase, 0.35 N.m at 400 V three phase, and 0.35 N.m at 480 V three phase, with the same 290 W continuous power envelope at 400 V and 480 V versus 160 W at 230 V single phase — so a single-phase feed costs roughly 45% of the rated continuous output and is only the right call for light-duty axes. Peak stall torque is 1.5 N.m and the continuous stall torque 0.42 N.m across the 115...480 V three-phase window, with nominal speed climbing 4000 rpm at 230 V single phase, 8000 rpm at 400 V three phase, and 9000 rpm at 480 V three phase — the same motor covers a 2.25× speed range just by changing the feed. The drive-current envelope is bounded by 0.73 A continuous stall current, 2.9 A maximum Irms, and 2.9 A 3-second peak output current; back-EMF constant 40 V/krpm at 20 °C and torque constant 0.58 N.m/A at 120 °C let the Lexium sizing tool map any point on that envelope to a drive model without bench characterisation.
Shaft, inertia, and the loads it will accept
The shaft is 9 mm diameter with a parallel key (3 mm key width) and a 20 mm shaft length — sized for small gear, pulley, or direct-coupled pinion loads on conveyors, indexers, and light rotary tables.
Sealing, cooling, and the IP rating in context
Cooling is natural convection with a 130 °C copper-hot temperature ceiling — no fan or blower to specify in the panel thermal budget, which is what the 55 mm frame is sized for. The motor body carries IP65 per IEC 60034-5 (shaft bushing IP54 without the optional shaft seal ring), so the SH3 sits happily on a washdown-adjacent line or in an outdoor cabinet once the cable gland on the quicklock connector is torqued to its seal — the limit is the shaft exit, not the housing.
Sourcing posture for an active BOM line
Cross-reference is by sizing reference SH30551P1BF4000 in the SH3 family; no alternate order code sits in the ledger for a second-source comparison.
