Overview
The Siemens IFK7101-5AF71-1EG3-Z is a permanent magnet excited synchronous servo motor from the SIMOTICS S-1FK7 series. This compact servo motor combines superior overload capability with exceptional ruggedness, making it a proven solution for high-performance motion control applications in industrial automation. The motor features an absolute EnDat encoder with 2048 pulses per revolution, providing precise feedback for closed-loop control systems.
Key Features
- Permanent magnet synchronous motor technology with excellent dynamic response
- Compact frame size (100 mm shaft height) for space-saving installation
- Absolute EnDat 2048 encoder for accurate position feedback
- Natural air cooling with IP64 degree of protection
- Plain shaft with tolerance N; no holding brake
- Rotatable power/signal connectors (270° rotation capability)
- Designed for automotive, aerospace, and industrial motion control applications
Technical Specifications
This servo motor is rated for continuous operation at 3000 RPM with 27 Nm torque output and 4.85 kW power. The motor operates on three-phase AC power with standard industrial frequencies. Cooling is naturally convected, eliminating the need for external cooling systems. The IP64 enclosure rating ensures protection against dust and water ingress, suitable for demanding factory environments.
Typical Applications
The Siemens IFK7101-5AF71-1EG3-Z excels in machine tools, robots and handling systems, wood/glass/ceramic/stone working equipment, packaging and textile machinery, and printing equipment. Its high power density and compact design make it ideal for auxiliary axes and retrofit projects where space is limited but performance cannot be compromised.
Compatibility & Replacements
This motor is part of the widely-adopted 1FK7 servo motor family and integrates seamlessly with Siemens SINAMICS S120 drive systems. Compatible with standard servo motor couplings and 192×192 mm flange mounting interfaces. For similar ratings, variants within the 1FK7101-5AF71 series (such as 1EG0, 1EG2, 1EH0, 1GA0) may serve as alternatives. Verify encoder type and shaft configuration before substitution.
