Why this 55 mm SH3 fits the axis
The Schneider Electric SH30552P1BA4000 is the SH3 servo motor with a 55 mm international-standard flange, a 9 mm parallel-key shaft, and a 154.5 mm body length — sized for compact axes where a 0.71 N·m continuous stall at 1.2 A is enough torque without overshooting the panel real-estate budget.
Duty envelope across the supported supply rails
Nominal torque scales with the input rail: 0.75 N·m at 230 V single-phase, 0.63 N·m at 400 V and 480 V three-phase, while nominal output power reaches 530 W on the three-phase rails against only 280 W on the single-phase supply. Peak stall torque is 2.5 N·m across the full 115–480 V three-phase range with a 4.8 A Irms ceiling, so the same motor covers both the continuous-duty rating and the short acceleration bursts the drive will command. Maximum mechanical speed is 9000 rpm, and natural-convection cooling is the only thermal path — derating begins once the ambient pushes the winding copper temperature toward the 130 °C hot-spot ceiling.
Feedback, connector, and load-handling envelope
Feedback is an absolute multiturn Hiperface DSL encoder over a rotatable right-angle quicklock connector, which keeps the single-cable hybrid path on a tight swing arm and avoids the second cable a resolver would require. Maximum radial load is 190 N at 8000 rpm and maximum axial load is 40 N; either limit will be the binding constraint on belt- or pinion-coupled axes well before the motor's own torque ceiling.
