Unique Snake Line Technology to achieve reduction of eddy current loss. According to the relevant conclusions, Snake Line Technology has more competitive advantages compared with laminated magnet, especially dimensional accuracy, mechanical properties, and cost.

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.

High efficiency demands the best material, and the laminated rare earth magnets are proven to reduce eddy current losses in high efficiency motors. Fewer eddy current losses means lower heat and greater efficiency. N46UH Sintered Neodymium Segment Snakeline Magnets

Laminated magnet is to cut the whole magnet into many small magnets, and then use specific glue to bond together. These samll magnets are insulated form each other and can down lectromagnetic eddy current.

When the permanent magnet motor is running, the motor will generate harmonic and the magnet will generate skin effect, these all will bring a lot of eddy current loss. And then, the temperature of permanent magnet rises, which results in irreversible demagnetization and affects the safety and stability of motor operation. So the design of laminated magnet can just cut down this risk. N38UH Arc Sintered Neodymium Snakeline Magnet Ni-Cu-Ni Coating
