Speed and torque across supply voltages
The SH30553P01A1200: This SH3 frame servo motor delivers 680 W continuous power, but the speed and torque curves shift depending on what supply you feed it. On three-phase 400 V or 480 V it spins to 6000 rpm; on single-phase 115 V it tops out at 2000 rpm, and at 230 V single-phase it reaches 4000 rpm. Nominal torque follows the same pattern: 1.13 Nm at 115 V single-phase, 1.1 Nm at 230 V single-phase, and 0.81 Nm on both 400 V and 480 V three-phase supplies. The peak stall torque is 3.5 Nm across the 115-480 V three-phase range, so there's headroom for acceleration spikes.
Encoder feedback and mounting constraints
The absolute single-turn SinCos Hiperface encoder gives position feedback on power-up without a homing sequence, which saves a cycle on multi-axis machines. The smooth shaft (9 mm diameter, 20 mm length) means you need a clamping coupling — no keyway to transmit torque. Mounting is via an international standard flange with a 55 mm square pattern, four 5.5 mm holes, and a 40 mm pilot diameter. The centring collar depth is 2 mm, so the motor registers into the mating face before the bolts tighten. Natural convection cooling means no fan noise or filter maintenance, but the thermal budget depends on the enclosure's airflow.
Sealing and environmental rating
IP65 on the motor body and shaft bushing, IP67 on the housing — both per IEC 60034-5. That means the motor withstands hose-down cleaning and temporary immersion at the shaft seal. The straight electrical connector (not angled) simplifies cable routing in tight cabinets but needs clearance for the mating plug's bend radius.
