Supply-dependent speed and torque — the real selection numbers
The SH31004P1BF4100: Nominal torque follows the same pattern: 9.5 N.m at 230 V single-phase, 7.9 N.m at 400 V three-phase, and 6.9 N.m at 480 V three-phase. The continuous power rating is 2500 W, but nominal output power varies — 1490 W on 230 V single-phase, 2480 W on either 400 V or 480 V three-phase. Peak stall torque reaches 40.5 N.m across the 115...480 V three-phase range, while continuous stall torque is 10 N.m — the 4:1 ratio tells you this motor can accelerate a high-inertia load quickly but thermal limits set the sustained output.
Encoder and feedback — single-cable absolute position
The absolute multiturn Hiperface DSL encoder communicates position and temperature over a single cable pair — no separate feedback cable, no battery needed to retain position through power cycles. The rotatable right-angle connector with quicklock termination lets you orient the cable exit in tight cabinets without a right-angle adapter.
Holding brake and mechanical interface
The integrated holding brake delivers 12 N.m static torque — sized for vertical-axis loads where the motor must hold position with power off. Shaft is 24 mm diameter with a parallel key, 50 mm shaft length, 8 mm key width — standard IEC metric interface, mates with most common couplings and pulleys. Motor flange is 100 mm (3.9 in) with a 95 mm centring collar and 9 mm mounting holes — international standard flange pattern, no adapter plate needed for common gearbox mounts.
Environmental rating and cooling
IP65 on both the motor body and the shaft bushing per IEC 60034-5 — the seal at the shaft exit is rated for direct washdown, not just the housing. Cooling is natural convection — no external fan or forced air required, but the motor relies on its own surface area and mounting flange for heat rejection. Copper winding temperature limit is 130 °C (266 °F) hot-spot; the torque constant is specified at 120 °C (248 °F) winding temperature, so the published 1.62 N.m/A reflects hot operation, not cold start.
Electrical parameters for drive sizing
Maximum RMS current is 32.3 A, with a 3-second peak current also 32.3 A — the drive must supply this peak for acceleration without tripping on overcurrent. Stator resistance is 1.8 Ω and inductance is 13 mH — these set the electrical time constant and influence the drive's current-loop tuning parameters. Back EMF constant is 103 V/krpm at 20 °C (68 °F) — at 3000 rpm the motor generates 309 V line-to-line, which must stay below the drive's DC bus voltage for proper current control.
