Voltage-dependent torque — the spec that decides your fit
The SH32053P11A2000: This SH3 series servo motor delivers 84.9 N·m nominal torque on 115 V single-phase supply, but only 40.2 N·m on 480 V three-phase — the torque drops more than half as voltage rises. That's not a flaw; it's the winding design. If your line runs 400 V three-phase, the 50.7 N·m at 2000 rpm is your working number, not the 115 V figure. Continuous power tops out at 10.6 kW at 400 V three-phase, with 10.1 kW at 480 V. The 136.1 A peak current (3-second rating) tells you the drive needs to handle that surge without tripping — size the drive for the peak, not the continuous.
Encoder and feedback — what the Hiperface signal means for your drive
The absolute single-turn SinCos Hiperface encoder gives position at power-up without a home cycle — critical for applications where the machine must know its location immediately after a power loss or emergency stop. Single-turn means it tracks one revolution; for multi-turn applications you'd need a different encoder option. The SinCos analog track also provides velocity feedback with higher resolution than incremental encoders — expect smoother low-speed operation if your drive supports SinCos interpolation.
Mounting and environmental sealing
IP54 with the standard shaft bushing (no shaft seal ring) — that's splash protection but not washdown. Add the IP65 shaft bushing option for environments where coolant mist or light spray is present. The motor body itself is IP65-rated per IEC 60034-5. Natural convection cooling — no fan means no fan noise or filter maintenance, but also means you can't overspeed the motor beyond its thermal limit without external airflow. The 130°C copper hot-spot temperature is the ceiling.
Sourcing — current production, no cross-reference needed
The SH32053P sizing reference anchors this in the SH3 family — if you're replacing a failed unit, confirm the encoder type (Hiperface absolute single-turn) and the shaft configuration (parallel key, no holding brake) match your original order code.
