What you're actually buying
The SH32052P12F2100 is an SH3-series three-phase AC servo motor sized for the high end of the family's continuous-power band: 7900 W continuous power and 80 N.m holding torque, with a 220 N.m peak stall torque ceiling across the 115–480 V range. It comes with an integrated holding brake and an absolute multiturn SinCos Hiperface encoder, terminated through a straight connector — field-replaceable in most cabinet builds, but the encoder protocol is the binding choice: any replacement drive stage on the machine must speak Hiperface on the feedback channel.
Voltage curve — read this before you size the drive
Nominal speed scales with 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 — meaning a single motor carries four distinct speed/power points and the drive must be commissioned to match the actual mains, not the headline figure. Nominal torque follows the same pattern: 61.6 N.m at 115 V, 56 N.m at 230 V, 38.1 N.m at 400 V, and 28.4 N.m at 480 V — peak mechanical power lives at 400 V three-phase (7980 W nominal output), with 480 V delivering more speed but ~25% less torque than the 115 V single-phase point. Continuous stall torque is 64.9 N.m across 115–480 V three-phase, so the thermal floor is set by the copper-hot rating of 266 °F (130 °C) under natural convection cooling — a heatsink or forced-air fan is not in the spec, which means cabinet airflow has to carry the dissipative load.
Drive-side electrical constants
Back-EMF constant is 161 V/krpm at 20 °C and torque constant is 2.52 N.m/A at 120 °C — together they define the current command for any torque setpoint and confirm the motor wants ~32 A rms per 80 N.m of torque at the operating temperature. Stator resistance is 0.3 Ohm and stator inductance is 2.95 mH; maximum rms current is 96.8 A, which is also the 3-second peak output ceiling — current-loop tuning must clamp below that figure to avoid nuisance trips on acceleration ramps.
Mechanical fit, shaft load, and IP65
Frame is the 205 mm international-standard flange (8.07 in) with 14 mm mounting holes, 17.9 in (454.5 mm) overall length, and a 38 mm shaft with a 10 mm parallel key and 80 mm shaft length — a standard IEC mounting footprint that drops into most machine-builder adapter plates without re-machining. Shaft load limits are derated with speed: maximum radial force Fr is 4200 N at 1000 rpm, dropping to 3330 N at 2000 rpm and 2910 N at 3000 rpm; maximum axial force Fa is 740 N — the radial ceiling governs pulley or pinion mounting, and any direct-coupling choice needs to keep the overhung load below that curve for the worst-case operating speed. Sealing is IP65 on both the motor body and the shaft bushing per IEC 60034-5 — splash-resistant and dust-tight, which is enough for typical washdown-adjacent cabinet exterior mounting but not for direct food-zone exposure where IP67K/IP69K would normally be specified.
Lifecycle and sourcing
Lifecycle is recorded as current on the part record; no official successor or LTB notice is on file for the SH32052P12F2100 variant, so it ships against the active BOM — though any PCN/EOL change in the SH3 family would land here first. The sizing reference SH32052P12F2100 points at the SH32052P frame size, so a swap stays within the same frame — but connector orientation, encoder protocol, and brake option would all need to be matched before a cross-reference is safe.
