What does this motor put on the shaft at each supply rail?
The SH3 series SH30402P1DA4000 is a brushless servo motor sized around the 40 mm flange footprint, with the reference designation SH30402P carrying through the order code, and the catalog slot is 'servo motor' rather than 'servo motor with brake' because this build ships without a holding brake — a meaningful distinction for any retrofit where a fail-safe brake was assumed. Nominal torque reads 0.37 N.m at 230 V single phase and 0.31 N.m at both 400 V three phase and 480 V three phase, while nominal speed reaches 4000 rpm at 230 V single phase and climbs to 9000 rpm at both 400 V and 480 V three phase — meaning the same physical motor delivers a higher base speed on a three-phase feed, and the integrator selects the drive rating around the intended supply rather than the headline number alone. Continuous output power is 152 W at 230 V single phase and 292 W at both 400 V and 480 V three phase, with continuous power also documented at 290 W in the spec set — the three-phase feed roughly doubles the sustained shaft power because speed climbs faster than torque drops.
How does the mechanical interface line up with the driven load?
The shaft is 8 mm diameter with a 25 mm length, a parallel key seat at 3 mm key width, and an international standard flange mount — the 40 mm motor flange mates to a gearbox or coupling on a standard pilot, and the parallel key transmits torque without a slip-fit risk under cyclic loading. Electrical connection is a quicklock rotatable right-angled connector, which lets the cable exit be set after the motor is bolted down — useful where the cabinet layout forces the harness direction and a straight connector would kink the cable.
What does the feedback channel and sealing actually deliver?
The encoder is an absolute multiturn Hiperface DSL with a 32768 points/turn resolution across 4096 turns — single-cable digital feedback that carries absolute position over the motor power conductors, removing the need for a separate encoder cable run back to the drive. Sealing is IP65 on the motor body to IEC 60034-5 and IP54 at the shaft bushing without an additional shaft seal ring — meaning the motor tolerates washdown and dust ingress on the housing, but the through-shaft path is the weaker interface and any liquids creeping along the shaft will reach the windings unless a sealed breather or shaft seal is added on the application side. Cooling is natural convection only — no integrated fan — so the continuous ratings assume a free air envelope around the housing, and fitting a shroud or stuffing the motor into a sealed box will erode the 0.37 N.m continuous figure.
What are the winding electricals and thermal headroom?
Continuous stall current is 1.5 A drawing a continuous stall torque of 0.39 N.m across the full 115 to 480 V supply window, and the drive must source up to 7.2 A Irms at peak — so sizing the servo drive around the Irms ceiling (not the nominal) prevents current-limit foldback during acceleration peaks. Peak stall torque reaches 1.5 N.m at 480 V three phase — roughly four times the continuous figure — which sets the worst-case acceleration torque the drive must deliver before tripping, and the back emf constant of 18 V/krpm at 20 °C with a torque constant of 0.26 N.m/A at 120 °C lets the integrator convert the demanded torque into a current command without re-deriving the motor constant. Winding resistance is 11.6 Ohm with a stator inductance of 12.8 mH across a 5-pole construction, copper hot temperature rated to 130 °C, and a maximum mechanical speed of 10000 rpm — the 11.6 Ohm figure is high for a 0.37 N.m class, which is consistent with the high-impedance design that lets one motor cover a 115 to 480 V supply range without a rewinding step.
Where does this part sit on the lifecycle sheet, and how is it sourced?
Lifecycle stage reads current on the spec set, meaning the part is in normal production at the time the record was compiled — no last-time-buy window on file, and no official L-tagged successor listed, so any retrofit should target this order code directly rather than migrate to a near-name sibling. Pricing and availability for SH30402P1DA4000 are confirmed at quote time against the BOM line — the part is specified into the build rather than held as off-the-shelf shelf stock, and lead time scales with the quantity, encoder option, and connector orientation when the BOM is non-standard.
