Is the SH32053P12F1200 still active, and what does it actually drive?
At 205 mm flange and a 21.2 in (538.5 mm) body length, this motor is sized for the mid-frame machine-tool axis, indexing table, or packaging-line rotary knife — anywhere the load benefits from a continuous 80 N.m and can spike into the 330 N.m peak torque envelope. Continuous stall torque of 94.4 N.m at 115–480 V three phase and peak stall torque of 330 N.m at the same range frame the duty window for the downstream drive sizing.
Torque envelope, supply rails, and where the drive sits
Nominal torque drops as the supply rail rises — 84.9 N.m at 115 V single phase, 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 — because nominal speed rises with voltage (500 / 1000 / 2000 / 2400 rpm respectively). Continuous power is listed at 10600 W, and nominal output power tracks the supply rail — 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. On a 400 V three-phase bus the motor reaches the published continuous-power ceiling, so a drive kVA that matches the 400 V rail is the most efficient pairing. Maximum current is 136.1 A and the 3-second peak output is also 136.1 A — the peak envelope equals the continuous stall ceiling on this frame, which sets the bridge amplifier rating rather than the steady-state RMS demand. Stator resistance is 0.2 Ohm and stator inductance 2.05 mH, so the drive's current-loop bandwidth needs a bus-capable IGBT stage rather than a relay-grade contactor.
Shaft, flange, and the mechanical envelope
Shaft is 38 mm diameter with a parallel key 10 mm wide and 80 mm of usable length, exiting an international standard flange with 14 mm mounting holes and 4 mm centring collar depth. Verify the gearbox or coupling bore before specifying — the shaft diameter is the dimension that mates with the load side, not the flange OD. IP65 on the motor body and shaft bushing, IP67 on the housing — the housing rating permits washdown areas, while the shaft seal is rated only to IP65 so high-pressure hot water jetting must not be directed at the shaft seal face. Cooling is natural convection, so the cabinet must leave clearance around the housing; the rated continuous torque does not assume a fan-cooled surface. Maximum radial load is 4500 N at 1000 rpm, 3570 N at 2000 rpm, and 3120 N at 3000 rpm; maximum axial load is 740 N. Belt drives and pinion mounts must stay inside these envelopes or the bearing life spec collapses regardless of how the torque envelope looks on paper.
Inertia stack, brake, and what an axis swap adds
Back-EMF constant is 172 V/krpm at 20 °C, so peak line-to-line voltage at top speed directly tells the integrator what bus voltage range is required to avoid field weakening. Five motor poles, single-pole-pair-per-phase winding; the electrical frequency at 2400 rpm rises into the audio band and the drive's switching-carrier choice will need to stay above it.
Supplying the SH32053P12F1200 against a BOM
Sizing reference is SH32053P, so any cross-reference inside the same SH3 family matches on that base code — the F1200 suffix here is the configuration stamp for the encoder plus brake package, not a separate performance curve. Replace decisions should stay inside the SH3 SH32053P envelope to keep the drive and gearing aligned.
