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.
