Snakeline magnet is a new technology innovated by Bomatec, which is designed to minimize eddy current losses. This technology is considered to have superior advantages over laminated magnets, particularly in terms of dimensional precision, mechanical strength, and cost-effectiveness. It offers several advantages over traditional laminated magnets:
1. Cost-Efficient Manufacturing: Reduces magnet numbers and assembly costs with a segmented design.
2. Flexibility: Customizable shape, fill factor, and mechanical properties.
3. Material and Waste Reduction: Simplified manufacturing saves materials and reduces waste.
4. Environmental Impact: Minimizes waste, especially for expensive and environmentally sensitive materials.
5. Precision: Wire-erodes serpentine patterns directly into magnets, avoiding cutting and gluing.
6. Customization: Special epoxy filling methods ensure strength and enable rapid implementation of custom designs.
Laminated magnets require hours of manual labor and produce a significant amount of waste. Snakeline magnets simplify this process. Industrial-precision wire EDM machines create cuts in the finished magnet, eliminating the traditional methods of slicing, stacking, and re-gluing magnets together. This efficient process results in time saved and less material waste, especially required with expensive samarium cobalt magnetic material. With our proprietary epoxy filling technique already mature and deployed with our manufacturing partners, Bomatec has the capacity to quickly and efficiently deploy a Snakeline process across your design.
