Motor ratings that govern the drive selection
The SH31004P01F2100 is a three-phase servo motor with a 100 mm international standard flange and a smooth shaft — the flange size tells you the frame mates with standard gearboxes or machine mounts, and the smooth shaft means no keyway, so the coupling must transmit torque through a clamping hub (cites:,). Nominal speed depends on the supply voltage: 3000 rpm at 400 V three-phase, 3600 rpm at 480 V three-phase, and lower speeds on single-phase supplies (750 rpm at 115 V, 1500 rpm at 230 V) — the drive must be configured for the actual line voltage to get the rated speed (cites:). Nominal torque also varies with voltage: 7.9 N.m at 400 V three-phase, 6.9 N.m at 480 V three-phase — the torque constant is 1.62 N.m/A at 120 °C copper temperature, so the drive's current loop directly sets the available torque (cites:,). Continuous power is 2500 W — this is the thermal limit for sustained duty under natural convection cooling; no fan means the motor relies on the mounting surface and ambient air to shed heat, so duty cycle must be checked against the application profile (cites:,).
Holding brake and encoder — what they mean for the machine
The holding brake delivers 12 N.m of holding torque — enough to keep a vertical load stationary when power is removed, but it is a holding brake, not a dynamic braking resistor; do not use it to decelerate the motor under normal operation (cites:). The absolute single-turn SinCos Hiperface encoder retains position across power cycles — no homing sequence is needed on restart, which saves time on machines that cycle power frequently or have long index moves (cites:).
Peak torque and mechanical limits for sizing
Peak stall torque is 40.5 N.m across the 115–480 V three-phase range — this is the short-term overload capability for acceleration, not continuous; the drive must supply 32.3 A peak to reach this torque (cites:,). Maximum radial force is 1070 N at 1000 rpm, derating to 740 N at 3000 rpm — this sets the bearing load limit for belt or pulley drives; exceeding it shortens bearing life. Maximum axial force is 160 N for direct-coupled loads (cites:,). Stator resistance is 1.81 Ohm and stator inductance is 6.5 mH — these values feed the drive's autotuning routine for current loop gains; a mismatch between the drive's motor model and these parameters causes torque ripple or instability (cites:,).
IP65 and environmental sealing
The motor and shaft bushing are rated IP65 per IEC 60034-5 — the housing withstands hose-directed water and dust ingress, making it suitable for washdown environments in food processing or packaging lines (cites:). Electrical connection is via a straight connector (rotatable right-angled connector also available) — the connector orientation must be planned in the cable tray layout to avoid bending the cable beyond its minimum bend radius (cites:,).
