What this servo is sized for
The Schneider Electric SH32052P02A2000 is the SH3 family servo in a 205 mm flange, 405 mm long, with an absolute multiturn SinCos Hiperface encoder and a smooth 38 mm shaft — so it drops into the standard SH3 mounting footprint rather than a one-off mechanical interface. Natural convection cooling and IP65 on the motor body with IP54 at the shaft bushing put it inside an enclosure on a machine frame, not out in washdown or outdoor exposure. Continuous power is 7900 W; the continuous stall envelope is 64.9 N·m at 25.7 A stall current, with a peak stall ceiling of 220 N·m reached through a 96.8 A 3-second peak output — that headroom is what lets the drive push the motor into accel/decel transients without tripping on the first hard move.
Performance envelope across the supply rails
Nominal speed and torque scale with the bus the drive is wired to: 500 rpm and 61.6 N·m at 115 V single-phase, 1000 rpm and 56 N·m at 230 V single-phase, 2000 rpm and 38.1 N·m at 400 V three-phase, 2400 rpm and 28.4 N·m at 480 V three-phase. The same motor on a 480 V drive delivers the broadest speed range but the lowest continuous torque — pick the rail that matches the load's duty point rather than the headline rpm figure. Continuous output power follows the same curve: 3230 W on 115 V single-phase, 5860 W on 230 V single-phase, 7980 W on 400 V three-phase, 7140 W on 480 V three-phase — the 400 V three-phase point is where this frame delivers its rated 7900 W most efficiently, so most cabinet builders land there unless the site distribution forces a 480 V feed.
Mechanical integration and shaft loading
Maximum radial force Fr on the shaft is 4200 N at 1000 rpm, 3330 N at 2000 rpm, and 2910 N at 3000 rpm; maximum axial force Fa is 740 N. For belt or pinion drives those Fr numbers cap the permissible pulley diameter and belt tension at the operating speed — running at 2000 rpm means the coupling design has to stay inside a 3330 N radial budget or the bearing life shortens. The motor flange follows the international standard flange pattern with 14 mm mounting holes and a 180 mm centring collar — the same SH3 mechanical interface across the frame family, so a cabinet redesign only has to confirm shaft length (80 mm,) and the encoder connector position rather than re-machining the mount.
Electrical constants for drive sizing
Rotor inertia includes no brake contribution; this build is supplied without a holding brake — a vertical-axis application that needs a fail-safe stop has to spec an external brake or move to a braked SH3 variant. Connection is via a straight connector with a rotatable right-angled option — the rotatable head is the cabinet-side detail that decides how the cable gland lands on the drive without fouling the cabinet bend radius. Winding thermal limit is 130 °C copper hot and the frame carries a 5-pole design — those two together set the continuous current ceiling the drive must respect in the motor thermal model, not just the headline stall current.
