ETEL IWM040-0256-00A Ironcore Linear Motor Magnetic Way – High-Force Magnet Track
The ETEL IWM040-0256-00A is a high-performance ironcore linear motor magnetic way, also referred to as a magnet track. This component serves as the stationary magnetic field source for ETEL's ironcore linear motor systems, providing the foundation for high-force, high-precision 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.
Ironcore linear motor technology provides higher force output compared to ironless designs, making the IWM040-0256-00A particularly suitable for applications that require high thrust and rapid acceleration, such as machine tool feed drives, heavy-duty positioning systems, and large-format manufacturing equipment. 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.
Key Features
Ironcore Architecture: Provides high force density and excellent thermal performance for demanding applications.
High Force Density: Advanced magnet materials maximize thrust output within a compact footprint.
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 IWM040-0256-00A magnetic way features a magnet pitch optimized for high-force applications. It is compatible with ETEL's ironcore 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 "040" 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 industrial environments, with robust construction suitable for machine tool applications.
Applications
Machine Tools: High-performance feed drives for milling, turning, and grinding machines.
Semiconductor Manufacturing: Wafer handling and inspection stages requiring high force.
Heavy-Duty Automation: Large-format positioning systems for automotive and aerospace manufacturing.
Laser Processing: High-speed cutting and welding tables.
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.
Benefits
High Force Output: Delivers exceptional thrust for demanding applications.
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.
Design Flexibility: Modular segments allow customization of stroke length.
Conclusion
The ETEL IWM040-0256-00A ironcore linear motor magnetic way is a precision-engineered component that forms the backbone of high-force direct drive linear motion systems. Its combination of high force density, robust construction, and modular flexibility makes it an ideal choice for applications demanding the highest levels of thrust, speed, and reliability.
