ETEL IWM060-0256-00 Ironless Linear Motor Magnetic Way – Precision Magnet Track
The ETEL IWM060-0256-00 is a high-performance ironless linear motor magnetic way, also referred to as a magnet track. This component serves as the stationary magnetic field source for ETEL's ironless linear motor systems, providing the foundation for ultra-smooth, cogging-free linear motion. Designed with advanced permanent magnet materials and precision manufacturing techniques, this magnetic way delivers exceptional force density, thermal stability, and long-term reliability in demanding industrial environments.
Ironless linear motor technology eliminates the attractive force between the coil assembly and the magnet track, resulting in zero cogging and minimal force ripple. This characteristic makes the IWM060-0256-00 particularly suitable for applications that require extreme smoothness at low velocities, such as scanning, inspection, and ultra-precision positioning. The magnet track is constructed with a modular design, allowing multiple segments to be joined end-to-end to achieve virtually any stroke length required by the application.

Zero Backlash: Direct drive operation removes mechanical transmission elements, providing immediate response and high precision.
Modular Design: Track segments can be combined to create custom stroke lengths, offering flexibility for various machine designs.
Thermal Stability: Engineered to maintain consistent magnetic performance across a wide operating temperature range.
Durable Construction: Protective coating resists corrosion and mechanical damage, ensuring long service life.
Technical Specifications
The IWM060-0256-00 magnetic way features a magnet pitch optimized for high-speed and high-force applications. It is compatible with ETEL's ironless coil assemblies, delivering continuous forces up to several hundred newtons and peak forces exceeding one thousand newtons, depending on the coil configuration. The track width and height are designed to fit standard linear motor mounting interfaces, simplifying integration into existing machine structures. The magnet array is precisely magnetized and inspected to ensure uniform field distribution along the entire track length.
Each segment has a length of 256 mm, with the designation "060" indicating the specific magnet grade and configuration. The track is mounted using precision-ground reference surfaces and pre-drilled mounting holes, allowing for accurate alignment during installation. The unit operates effectively in cleanroom environments, with low outgassing materials suitable for semiconductor and biomedical applications.
Applications
The ETEL IWM060-0256-00 is widely used in:
Semiconductor Manufacturing: Wafer handling, reticle positioning, and inspection stages.
Flat Panel Display Production: Glass substrate scanning and alignment systems.
Laser Processing: High-speed cutting, engraving, and marking tables.
Medical Device Manufacturing: Precision positioning for diagnostic equipment.
Metrology and Inspection: Coordinate measuring machines and optical inspection systems.
Installation and Alignment
Proper installation of the magnetic way is critical for achieving optimal motor performance. The mounting surface must be flat and rigid to maintain a consistent air gap between the magnet track and the coil assembly. ETEL provides detailed installation guidelines, including recommended torque values for mounting screws and alignment procedures using precision dial indicators. The track segments should be joined with minimal gaps to ensure smooth transition of the magnetic field, which is essential for uniform force generation along the entire stroke.
After installation, the air gap should be verified using feeler gauges or laser displacement sensors. The typical air gap ranges from 0.5 to 1.0 mm, depending on the specific coil assembly used. Correct air gap setting maximizes force output and prevents mechanical contact between moving and stationary parts. Periodic inspection of the track surface for contamination or damage is recommended to maintain long-term performance.
Benefits for Machine Builders
Superior Motion Quality: Zero cogging and low force ripple enable ultra-smooth velocity control, essential for scanning and inspection tasks.
High Throughput: High acceleration capabilities reduce cycle times and increase productivity.
Maintenance-Free Operation: No mechanical contact between the magnet track and the moving coil eliminates wear and reduces maintenance costs.
Design Flexibility: Modular segments allow customization of stroke length to suit specific application requirements.
Energy Efficiency: High force-to-power ratio reduces energy consumption compared to conventional transmission-based systems.
Quality and Reliability
ETEL magnetic ways are manufactured under strict quality control processes, with each segment undergoing magnetic flux density testing and dimensional inspection. The materials used are carefully selected to ensure stable magnetic properties over the product's lifetime, with minimal degradation even after years of continuous operation. The protective coating provides resistance to common industrial contaminants, including coolants, oils, and dust particles, ensuring reliable operation in harsh environments.
Conclusion
The ETEL IWM060-0256-00 ironless linear motor magnetic way is a precision-engineered component that forms the backbone of high-performance direct drive linear motion systems. Its combination of cogging-free operation, high force density, and modular flexibility makes it an ideal choice for applications demanding the highest levels of precision, speed, and reliability. Whether used in semiconductor manufacturing, laser processing, or advanced metrology, this magnet track delivers the performance required to meet the challenges of tomorrow's automation needs.
