Where this SH3 servo lands on the machine
The Schneider SH32053P11F1200 sits in the SH3 sizing reference (SH32053P) as a high-torque three-phase servo for industrial automation lines — conveyors, machine-tool spindles, packaging axes, and indexing tables where the constant-torque envelope up to 5000 rpm matters more than a peak speed figure. It pairs with a Lexium-series drive (the SH3 short name and Hiperface SinCos encoder are the system identifiers a commissioning engineer will look for in the drive's motor database) through a straight connector at the motor housing — the encoder feedback is single-turn absolute SinCos Hiperface, so the drive returns the absolute shaft position on power-up without a homing move.
Torque envelope across the supply range
Holding torque is 708.06 lbf.in (80 N.m) with the integrated holding brake; continuous stall torque runs 835.5 lbf.in (94.4 N.m) at all listed supply voltages, and peak stall torque reaches 2920.7 lbf.in (330 N.m) at 115…480 V three phase — the rating that governs how aggressively the axis can accelerate a heavy load before the drive folds into current limit. Nominal torque drops as supply voltage falls: 751.4 lbf.in (84.9 N.m) on 115 V single phase, 658.5 lbf.in (74.4 N.m) on 230 V single phase, 448.7 lbf.in (40.2 N.m) on 400 V three phase, and 355.8 lbf.in (40.2 N.m) on 480 V three phase — a 400 V or 480 V three-phase feed is what unlocks the full continuous torque the servo is sized for.
Speed-power map by supply voltage
Nominal speed scales with the supply: 500 rpm at 115 V single phase, 1000 rpm at 230 V single phase, 2000 rpm at 400 V three phase, and 2400 rpm at 480 V three phase — lower-voltage operation trades speed for torque and is only useful for low-rpm, high-torque axes. Nominal output power tracks the supply as well: 4450 W at 115 V single phase, 7790 W at 230 V single phase, 10620 W at 400 V three phase, and 10100 W at 480 V three phase; the continuous power of 10600 W corresponds to the 400 V three-phase operating point.
Mechanical fit into the axis
The 8.07 in (205 mm) international-standard flange with 0.6 in (14 mm) mounting holes is the mechanical interface a panel builder or OEM wireman aligns to gearbox and coupling partners — a parallel key (0.4 in / 10 mm) on a 1.5 in (38 mm) diameter shaft with 3.1 in (80 mm) protrusion locks the coupling without a clamp fit. Overall length is 21.2 in (538.5 mm), so the servo needs clearance for the rear straight connector and bend radius inside the cabinet; centring collar depth is 0.2 in (4 mm) and the housing carries IP67 protection at the body, IP65 at the motor envelope and shaft bushing, all per IEC 60034-5 — meaning the SH32053P11F1200 tolerates washdown and dust-laden production cells without an additional shroud. Maximum radial force at the shaft end derates from 4500 N at 1000 rpm to 3570 N at 2000 rpm down to 3120 N at 3000 rpm; maximum axial force Fa is 740 N — these are the load limits the gearbox and belt drive must respect when the axis is running at full speed.
Winding electricals and thermal ceiling
Stator resistance is 0.2 Ohm and stator inductance is 2.05 mH; torque constant is 2.84 N.m/A at 248 °F (120 °C) and the back-EMF constant is 172 V/krpm at 68 °F (20 °C) — the latter defines the drive's DC-bus voltage budget to reach top speed before the regeneration limit collapses the field-weakening range. Maximum current Irms is 136.1 A and the 3-second peak output current matches that figure; copper-hot temperature is 266 °F (130 °C) on natural convection cooling, so the motor must be sited with the body free of insulating wraps and the airflow path the convection rating was measured against.
