Product details

Form factor and flange footprint

The SH30551P0AF4100: Shaft end is a 9 mm smooth shaft 20 mm long, with a 40 mm centring collar 2 mm deep and 5.5 mm mounting holes — the flange pattern aligns to the standard SH3 frame, so a panel cut and bolt circle carry over from a same-frame predecessor without re-machining.

Mechanical limits on the shaft

Maximum mechanical speed is 9000 rpm and maximum radial load Fr is 340 N at 1000 rpm, with a 40 N maximum axial force Fa — sized against a small pinion or timing-belt pulley, the bearing life budget is set by the radial load curve, not the continuous torque, because Fr drops as shaft speed rises.

Torque envelope across supply rails

Nominal torque is 0.5 N.m at 230 V single phase, dropping to 0.35 N.m at 400 V three phase and 480 V three phase, with continuous stall torque 0.42 N.m from 115 V to 480 V three phase — peak stall torque 1.5 N.m at 115 to 480 V three phase is the short-term ceiling the drive's current loop can command into the winding without saturating the inverter. Nominal output power tracks 160 W at 230 V single phase and 290 W at 400 V three phase or 480 V three phase, with 290 W continuous power at 130 °C copper hot — the motor is comfortably inside the 0.35 N.m class at three-phase mains and undersized only on the single-phase 230 V branch where torque falls back to 0.5 N.m at lower speed. Continuous stall current is 0.73 A and maximum Irms and 3-second peak current both sit at 2.9 A — the drive sizing is a function of the 2.9 A peak rather than the 0.73 A continuous figure, so a 3 A peak servo amplifier is the natural match.

Holding brake and feedback

The integrated holding brake delivers 0.8 N.m of holding torque at 10 W pull-in power — sized to hold a vertical axis in place with the motor unpowered, which is the standing duty for a small-format servo on a lift or indexing table where gravity loading has to be arrested on power loss. Feedback is an absolute single-turn Hiperface DSL encoder on a quick-lock rotatable right-angled connector — the single-cable DSL link carries power and position data on one cordset, so the cabinet entry drops to a single drag-chain run rather than separate motor power and feedback cables.

Thermal envelope, ingress, and motor model

Cooling is natural convection — no integrated fan — so the 130 °C copper-hot thermal ceiling is reached by surface radiation alone, and the motor is sized for cabinet mounting with clear airflow around the housing rather than a sealed enclosure. Both the motor body and shaft bushing carry IP65 to IEC 60034-5, sealing against washdown splashes and oil mist typical of a machine-tool or food-adjacent cell, but not against submerged or high-pressure jet service. The motor electrical model — 41.8 Ohm stator resistance, 37.13 mH stator inductance, 40 V/krpm back-EMF constant at 20 °C, and 0.58 N.m/A torque constant at 120 °C — is what the drive's auto-tuning routine reads on first commission; matching these constants is how the loop bandwidth is set before the first move command.

Lifecycle and sourcing posture

Lifecycle stage reads current on the record for the SH30551P0AF4100, with no LTB or PCN on file — the SH30551P sizing reference anchors it in the active SH3 family, so a same-frame replacement stays within the SH3 catalogue footprint without re-planning the cabinet layout. Quoted to order through independent distribution against the BOM line, with full Schneider Electric traceability on the shipment — lead time, quantity breaks, and current pricing confirmed at RFQ.

Frequently asked questions

What is the listed length of the SH30551P0AF4100?

The listed body length is 159 mm on a 55 mm international standard flange, with a 9 mm smooth shaft 20 mm long — the frame pattern carries over from any same-frame SH3 predecessor without re-machining the mounting surface.

What is the rotor and brake inertia of the SH30551P0AF4100?

Rotor inertia is 0.08 kg.cm²; the holding brake contributes 0.021 kg.cm² on top of the motor's 0.059 kg.cm², giving a low moving mass suitable for short-cycle indexing without external inertia-matching hardware.
