Frame and what lands on the bench
Schneider Electric SH32053P02A2100 is a SH3-series three-phase servo motor, 19.3 in (489 mm) long on an 8.07 in (205 mm) international-standard flange with a 7.09 in (180 mm) centring collar, sized off the SH32053P reference and built for direct mounting into the Lexium drive family. The shaft is a smooth 1.5 in (38 mm) diameter stub, 3.1 in (80 mm) long, without a holding brake — coupling and brake selection sit downstream of the BOM line rather than inside the motor.
Torque envelope buyers actually compare
Nominal torque scales with the supply the drive delivers: 84.9 N.m at 115 V single-phase (500 rpm), 74.4 N.m at 230 V single-phase, 50.7 N.m at 400 V three-phase and 40.2 N.m at 480 V three-phase — the single-phase 115 V winding is the torque-maximised configuration, while the 480 V three-phase drop reflects the higher speed ceiling, not a weaker motor. Peak stall torque is 330 N.m across the 115...480 V three-phase range and continuous stall torque holds at 94.4 N.m with a 33.2 A continuous stall current — that 3.5× peak-to-continuous margin is what the drive sizes acceleration profiles against in point-to-point moves.
Winding constants and drive matching
Back-EMF constant is 172 V/krpm at 68 °F (20 °C) and torque constant is 2.84 N.m/A at 248 °F (120 °C) winding temperature, so a drive's current-loop gain is set against 2.84 N.m/A rather than a cold-winding figure — the 33.2 A continuous stall current maps directly to the 94.4 N.m continuous stall torque through that constant. Stator resistance is 0.2 Ohm and stator inductance 2.05 mH on a 5-pole winding, with a peak Irms of 136.1 A and a 3-second peak output current rated to the same 136.1 A — the current-loop bandwidth and the short-term overload capability are the figures that drive the servo amplifier sizing decision. Copper-hot ceiling is 266 °F (130 °C), which sets the thermal envelope for the 10600 W continuous rating — derating begins above that copper temperature regardless of the ambient the cabinet sits in.
Shaft loading, cooling and sealing
Maximum axial force Fa is 740 N and maximum radial force Fr runs 4500 N at 1000 rpm, 3570 N at 2000 rpm and 3120 N at 3000 rpm — the radial figure drops as speed climbs, so a belt drive or pinion that looks comfortable at low speed may push past the bearing load curve once the line ramps up. Cooling is natural convection with no integrated fan, so the 10600 W continuous rating assumes a clean, unobstructed housing surface — panel builders who bury the motor inside an enclosure need to budget for external airflow or derate against the same 130 °C copper-hot ceiling. The motor carries IP65 on the housing and on the shaft bushing to IEC 60034-5, and the encoder is an absolute multiturn SinCos Hiperface device — feedback resolution and absolute position retention are both available on the same cable, with the electrical connection offered as a straight connector or a rotatable right-angled connector depending on the cabinet routing.
