Supply-dependent torque and speed — the key selection table
The SH30702M11A2000 is a 640 W continuous-duty servo motor from the SH3 series, and its output torque and speed are tied directly to the supply voltage and phase configuration — not a single fixed rating. On a 400 V three-phase line, nominal speed is 3000 rpm with nominal torque of 17.97 lbf.in (2.03 N·m). At 480 V three-phase, speed rises to 3600 rpm at the same torque figure. Single-phase 115 V yields 750 rpm at 19.5 lbf.in (2.2 N·m); 230 V single-phase gives 1500 rpm at 19.03 lbf.in (2.15 N·m). Peak stall torque reaches 67.3 lbf.in (7.6 N·m) across the 115–480 V three-phase range, while continuous stall torque is 18.06 lbf.in (2.04 N·m) over the same range — the peak-to-continuous ratio is roughly 3.7:1, which matters for acceleration duty cycles.
Encoder, feedback, and connection — what the Hiperface interface means
The motor carries an absolute single-turn SinCos Hiperface encoder — this is a digital-plus-analog interface that transmits absolute position within one revolution and sinusoidal analog tracks for high-resolution interpolation. It is not a multi-turn encoder, so the controller must handle revolution counting if the application needs absolute position across multiple turns. Electrical connection options include a straight connector and a rotatable right-angled connector — both are factory-fitted, not field-swappable, so the cable exit orientation must be specified at order time.
Thermal and mechanical limits for the mounting engineer
Cooling is natural convection only — no integrated fan. The motor relies on the machine frame or external airflow for heat rejection. Continuous stall current is 1.5 A, and the maximum continuous RMS current is 6.0 A; the 3-second peak current is also 6.0 A, meaning the drive's current limit should be set to this value to avoid demagnetisation. Maximum radial force Fr is load-dependent: 710 N at 1000 rpm, dropping to 390 N at 6000 rpm. Maximum axial force Fa is 80 N. These limits govern belt-tension and direct-coupling sizing — exceeding them shortens bearing life.
IP rating and shaft seal — washdown vs dry-environment fit
The motor carries IP54 at the shaft bushing without a shaft seal ring, and IP65 overall when the shaft bushing is sealed. The IP65 rating applies to the motor body and the shaft bushing with the seal ring fitted — this is a standard IEC 60034-5 classification, meaning dust-tight and protected against low-pressure water jets. Without the shaft seal ring, the bushing drops to IP54 (splash protection only).
