What the ratings mean on the line
The SH30702P0AF4100: This is a 70 mm flange servo motor from the SH3 family with a holding brake that locks the shaft at 3 N.m when power is removed — enough to hold a vertical load on a pick-and-place gantry without drifting during a power loss. The absolute single-turn Hiperface DSL encoder reports position on power-up without a homing move — saves a full minute per axis on a multi-axis machine startup, especially after a power cycle. IP65 rating on the motor body and shaft bushing means it handles washdown in food or packaging lines without needing a secondary cover — the seal is at the shaft exit, not just the housing.
Torque and speed for the application
Nominal torque is 2.1 N.m at 230 V single-phase, dropping to 1.8 N.m at 400 V or 480 V three-phase — the lower voltage limits the current loop headroom, so the motor delivers less torque from a single-phase supply. Nominal speed reaches 3000 rpm on 230 V single-phase, 6000 rpm at 400 V three-phase, and 7200 rpm at 480 V three-phase — the winding back-EMF constant is 48 V/krpm, so the speed ceiling is set by the DC bus voltage. Peak stall torque is 7.6 N.m across the 115...480 V three-phase range — this is the torque available for a short acceleration burst, not continuous duty; the continuous stall torque is 2.04 N.m.
