Where this motor sits on the machine
The 1FL2306-4AC01-1HB0: The part is a SIMOTICS S-1FL2 servomotor from the 1FL2 family that Siemens pairs with the SINAMICS S200 drive line, sized for a 400 V 3AC supply at 1.5 kW rated power and 2000 rpm rated speed with a 7.16 Nm rated torque and 8 Nm stall torque — so it lands on a motion axis where the S200 is already the chosen controller, not as a standalone motor swap. Shaft height 65 mm, an AS17-bit angular connector feedback device, a keyed shaft with Tolerance N, no holding brake, and IP65 protection with an oil seal — the mechanical and feedback choices are made at order time, which is why the order code carries the dash-suffix options (1HB0) rather than field-configurable accessories.
What the headline ratings decide for the panel builder
Pn=1.5 kW against a 400 V 3AC bus and Nn=2000 rpm sets the continuous shaft work envelope: the motor will run continuous duty at that speed with 7.16 Nm of torque, and the 8 Nm M0 figure is the stall ceiling the drive's torque-limit profile must respect during acceleration ramps and hold-position moves. M0=8 Nm against Mn=7.16 Nm gives roughly a 12% overload headroom above rated torque — useful margin for short accel/decel bursts but not a sustained-duty rating, so any cycle that runs the motor above Mn for more than a few seconds needs the S200 to be sized against the M0 figure, not the Pn figure. IP65 with oil seal at the shaft end means the motor is sealed against water jets and oil splash typical of a machine tool or gearbox housing — the seal excludes the wet/dirty side from the encoder cavity, provided that the cable gland at the AS17-bit connector is also torqued to its spec; IP65 is not IP67, so pressurised washdown or submerged service is outside the rating.
