Siemens 1FK7083-2AF71-1CG0 SYNCHRONOUS MOTOR 1FK7-CT 16 NM 3.3kW

1. Overview of the Siemens 1FK7083-2AF71-1CG0

The Siemens 1FK7083-2AF71-1CG0 is a 3.3 kW naturally cooled synchronous servo motor with a rated torque of 16 Nm and a maximum speed of 3000 rpm. It features a 600 V DC bus design and is plug-and-play compatible with the SINAMICS S120 drive system, providing highly dynamic and high-precision rotary motion for mid- to high-end automation equipment.

The motor is equipped with a 24-bit single-turn + 12-bit multi-turn absolute encoder (AM24DQI), which communicates with the drive via the DRIVE-CLiQ interface at high speed, achieving positioning repeatability of ±10 arc-second. Its IP64 protection and IMB5 flange ensure reliable operation in dusty and oil mist environments. The rotatable power connector allows for 270° adjustable wiring direction, saving time and effort in on-site maintenance. Typical applications include 3C placement machines, laser cutting, AGV wheels, and articulated robots. Its compact 100 mm flange and 11 kg lightweight body enable "install-and-use" upgrades within tight spaces at high production rates. With a two-year global warranty and readily available stock, it offers competitive pricing for OEMs in terms of lead times and after-sales costs.

2. Key Features
Wide Voltage Adaptation: Supports 380–480 V grids with 600 V after rectification The 120 series has a 1.5-level DC bus, allowing for direct plug-and-play integration with SINAMICS S120 power modules.
High dynamic response: With a rotor inertia of only 29.5 kg·cm² and an acceleration time constant of < 1.2 ms, it achieves sub-millisecond position loop cycles.
Precise positioning: A 24-bit, high-resolution absolute encoder delivers repeatability of ±10 arc-second, eliminating the need for zero return after power failure.
Intelligent thermal management: A built-in KTY84 temperature sensor monitors the drive's winding temperature in real time to prevent overload burnout.
Maintenance-free design: Lifetime lubricated bearings, a standard smooth axis, and optional keyway, brake, or planetary reducer options facilitate rapid OEM integration.

3. Typical Applications
• Robotic joints: The J4/J5 axes of 6-axis collaborative robots offer high torque density and reduced arm weight.
• Machine tool feed: A 30% cost-saving alternative to linear motors in the X/Y axes of machining centers. • Packaging Equipment: Vertical form-fill-seal machine film-pulling axis, 3000 rpm high-speed synchronization, ±0.02 mm positioning.
• New Energy: Lithium battery winding machine tension control, combined with an S120 servo drive, achieves a 400% overload acceleration for 3 seconds.
