The SH30701P1AF3100 is a 690 W SH3-series servo motor with an integrated holding brake, designed to drop into a standard 70 mm international flange — the same bolt pattern as many legacy servo frames, so no need to re-machine the mounting plate if you're swapping out an older motor. Nominal speed depends on your supply: 3000 rpm on 230 V single-phase, 6000 rpm on 400 V three-phase, and 7200 rpm on 480 V three-phase — the motor's torque curve shifts with the bus voltage, so match the drive's DC bus to get the speed you need. Nominal torque also varies: 1.4 N.m on 230 V single-phase, 1.1 N.m on 400 V or 480 V three-phase — the lower torque at higher voltage is a winding-configuration trade-off, not a derating; the continuous stall torque is 1.25 N.m across the 115...480 V three-phase range, which is the number to use for sizing the axis at low speed. The holding brake delivers 3 N.m holding torque — enough to keep a vertical axis from drifting when the drive is off — and draws 7 W to release, so factor that into the 24 V control supply budget.
Encoder and feedback — what Hiperface DSL means for the drive interface
The absolute single-turn Hiperface DSL encoder gives position feedback over a two-wire digital link — no separate encoder cable needed, just a hybrid power-plus-signal connection through the straight quicklock connector. Single-turn means the encoder tracks position within one revolution; on power-up it knows the shaft angle but not the absolute multi-turn count — if the application needs multi-turn absolute, this motor will need a homing cycle after a power loss. The torque constant is 0.69 N.m/A at 120 °C winding temperature — use this to map the drive's current limit to the available torque; the maximum RMS current is 5.7 A, so the peak torque available from the drive is about 3.9 N.m before the current limit clips.
Mounting and environmental fit
The motor body and shaft bushing are both rated IP65 per IEC 60034-5 — suitable for washdown environments as long as the mating connector is also IP65-rated and the shaft seal is intact. Cooling is by natural convection — no fan, so the motor relies on the machine frame or ambient airflow to carry away heat; continuous power is 690 W at rated conditions, but the thermal limit is set by the 130 °C copper hot-spot temperature.
No direct pin-compatible alternative is listed in the SH3 family — the sizing reference SH30701P points to the specific winding and flange variant; if you need a different torque-speed curve, the SH3 series offers other frame sizes and winding options, but the mounting footprint and encoder interface will differ.
