PM-Wire™ technology is revolutionizing the use of magnet alloys, enabling the use of low-cost or even rare-earth-free alloys. This technology not only enhances magnet performance but also significantly reduces production costs and helps address sustainability issues in the rare earth supply chain (Innovation News Network).
PM-Wire™ Technology is an innovative magnet manufacturing approach designed to enhance performance, reduce costs, and promote sustainability. Here are the key features and benefits of this technology:
High Performance and Low-Cost Alloys:
PM-Wire™ technology enables the use of low-cost or rare-earth-free alloys to manufacture high-performance magnets. For example, an inexpensive alloy called mischmetal (Mm) can partially replace neodymium-praseodymium (NdPr) in neodymium-iron-boron (NdFeB) magnets, reducing the critical rare earth content by 20-70% (Innovation News Network).
Versatile Shapes and Applications:
PM-Wire™ magnets can be produced in straight, ring, or helical shapes with continuously changing magnetization direction (continuous Halbach array), significantly reducing part count, mass, and simplifying assembly (Innovation News Network).
PM-AXIAL™ magnets are curved with axial magnetization, ideal for rotor topologies requiring breakthrough performance.
Reduced Dependence on Rare Earth Elements:
The technology allows the use of low coercivity (Hc) alloys in high-performance motors and generators. For instance, replacing NdFeB with FeN (iron nitride) alloys in electric vehicle motors can achieve or exceed the U.S. Department of Energy's power density targets (Innovation News Network).
Non-Sintered Alloy Applications:
Traditional NdFeB magnets typically require a sintering process, but PM-Wire™ technology allows the use of non-sintered alloys, significantly reducing equipment, processing, and labor costs. Non-sintered alloys like MnBi (manganese-bismuth) and FeN benefit from PM-Wire™'s unique features to achieve high performance without sintering (Innovation News Network).
Industrial Motors:
In traditional north-south motor topologies, high-grade NdFeB alloys (e.g., N48SH) are used for their high coercivity. PM-Wire™ technology enables the use of Mm and FeN alloys to achieve the same performance (Innovation News Network).
Electric Vehicles:
PM-AXIAL™ technology allows electric vehicle motors to use FeN alloys instead of NdFeB, meeting or exceeding power density requirements while reducing the reliance on rare earth elements (Innovation News Network).
By these innovations, PM-Wire™ technology not only enhances magnet performance but also significantly lowers costs and promotes sustainable practices in the magnet industry.
