SH3-frame servo, sized for the heavy end of the line
Schneider SH32053P12F2100 is a member of the SH3 servo family on a 205 mm international-standard flange, identified internally as sizing reference SH32053P (cites:,). Three-phase AC servo with a 5-pole-pair rotor (10 poles total), parallel-key shaft 38 mm diameter × 80 mm long, and an IP65 rating on both motor body and shaft bushing per IEC 60034-5 (cites:,). It carries an absolute multiturn SinCos Hiperface feedback device on a straight or rotatable right-angle connector, and ships with a holding brake integrated into the rotor stack (cites:,).
Torque and power envelope across the four mains classes
Holding torque is 80 N·m and continuous stall torque lands at 94.4 N·m over the full 115–480 V range; peak stall torque reaches 330 N·m, with a 3-second peak current of 136.1 A Irms — the figure a sizing engineer watches when the move profile demands an aggressive accel/decel (cites:,). Nominal torque and nominal output power swing substantially with the supply class: at 115 V single-phase the motor delivers 84.9 N·m at 4450 W; at 230 V single-phase 74.4 N·m at 7790 W; at 400 V three-phase 50.7 N·m at 10620 W; and at 480 V three-phase 40.2 N·m at 10100 W (cites:,). Continuous power is listed at 10600 W with natural-convection cooling and a 130 °C copper-hot thermal ceiling; nominal speed climbs with supply frequency from 500 rpm at 115 V single-phase to 2400 rpm at 480 V three-phase (cites:,).
Drive matching — back-EMF, torque constant, winding impedance
Back-EMF constant is 172 V/krpm at 20 °C and torque constant is 2.84 N·m/A at 120 °C — the pair that fixes which Lexium / servo drive voltage class this winding expects (cites:,).
Mechanical load envelope — thrust, overhung load, shaft detail
Maximum radial force Fr is rated 4500 N at 1000 rpm, 3570 N at 2000 rpm, and 3120 N at 3000 rpm — the numbers a gearbox or belt-drive designer pulls to size the overhung load before the bearing life budget collapses (cites:). Maximum axial force Fa is 740 N, the parallel key is 10 mm wide on a 38 mm shaft, and the centring collar depth is 4 mm — all values an integrator confirms against the driven-side coupling before the motor lands on the machine (cites:,). Mounting holes are 14 mm diameter on the 205 mm flange; the body length is 538.5 mm — the bracket-to-bracket dimension the mechanical designer needs before the BOM freezes (cites:,).
