Where this motor sits in a line
The Siemens 1FK2104-5AF00-2MB0 is a SIMOTICS S-1FK2 HD servo motor from the 1FK2 family built for pairing with SINAMICS S120 drives, so the drive-side controller, the DRIVE-CLiQ feedback link and the motor's encoder are designed as one closed loop rather than three independent purchases. Holding torque M0 = 2.4 Nm with a rated point PN = 0.75 kW at nN = 3000 rpm on the 380-480 V rail, and a secondary point PN = 0.375 kW at nN = 1500 rpm on the 200-240 V rail, so a single motor order code covers both the high-voltage European and the low-voltage North American feed without rewiring.
Encoder and connector stack
Feedback is the absolute encoder AM22DQC, 22-bit single-turn plus 12-bit multi-turn, which is what lets the SINAMICS S120 retain absolute position across power-down without an external battery box on the motor — important for any machine that homes on absolute position after a mains trip.
Shaft and the IP64 boundary
The shaft is a plain cylindrical D14 x 30 mm with no keyway detail on the order code, and the housing carries IP64 protection, so the motor is dust-tight and resistant to splashing water but is NOT rated for direct washdown — a cabinet or a cover is required on food, beverage or outdoor wet-side duty.
Lifecycle and sourcing posture
Compliance posture on file: RoHS conformity since 01-07-06, REACH Art. 33 information duty via the manufacturer's Reach Information statement, and export markings AL:N / ECCN:N_CNDU, which means the part is not dual-use controlled and is not on a national-authorisation list — cross-border shipments clear standard export review.
