PM-UNIFORM\u2122<\/strong><\/p>\n <\/p>\n
Consisting of straight, curved, ring, or helical magnets with transverse or radial magnetisation, these can be produced in metre lengths and offer lower cost assembly and reduced part count.<\/p>\n
PM-AXIAL\u2122 for motors<\/strong><\/p>\n <\/p>\n
These are curved magnets with axial magnetisation, allowing rotor topologies with breakthrough benefits. The PM-AXIAL has increased performance, with Halbach performance, higher temperature operation and a reduced overwrap and containment sleeve. By being iron free, it is also reduced in weight. Moreover, it has lower cost assemblies due to a reduced part count, ease of assembly and lower grade\/cost materials.<\/p>\n
PM-360\u2122<\/strong><\/p>\n <\/p>\n
Straight, ring, or helical magnets with \u2018continuously changing magnetisation direction\u2019, PM-360 offers increased performance, better than Halbach performance, as well as a reduced weight due to being iron free. The PM-360 also has a reduced part count and is easy to assemble, meaning lower cost assemblies for the REMI supply chain.<\/p>\n
PM-Wire solution examples<\/strong><\/p>\nReplacing conventional magnets with PM-Wire improves the performance and lowers the cost of motors. The following are three real-world examples showcasing the technology impact:<\/p>\n
\nAML replaces the north-south pole configuration in industrial motors with a PM-Wire configuration called PM-AXIAL. Using the same magnet alloy, this solution provides Halbach array performance, increases operational temperature by 20%, eliminates iron in the rotor and reduces the rotor overwrap thickness by 50%;<\/li>\n PM-360 topology replaces 2,750 Halbach arranged magnets in electric vehicle motors with eight PM-360 rings and eliminates the need to actively cool the motor rotor; and<\/li>\n PM-AXIAL topology can achieve the U.S. Department of Energy\u2019s electrical vehicle motor power density goals of 50 KW\/L with low or no rare-earth content materials.<\/li>\n<\/ul>\nAML technology and business execution<\/h3>\n AML\u2019s approach to the REMI supply chain is unique in technology and business. The company focuses on the end-use product and lets those requirements determine the best PM-Wire solution. AML does not compete in the commoditised, \u2018me-too\u2019, \u2018piece-part\u2019 magnet market.<\/p>\n
PM-Wire Development Phases<\/strong><\/p>\nThe PM-Wire development has followed a number of phases, including:<\/p>\n
\nPhase 1, where the process was validated using isotropic non-sintered NdFeB having uniform magnetisation;<\/li>\n Phase 2, which validated \u2018continuously changing magnetisation\u2019 (single-piece Halbach array) using anisotropic bonded NdFeB compositions;<\/li>\n Phase 3, which saw the design, build and commissioning of an advanced PM-Wire Pilot Manufacturing facility funded by the U.S. Department of Defence; and<\/li>\n Phase 4, which validated NdFeB sintered PM-Wire magnet configurations funded by the U.S.Department of Defence.<\/li>\n<\/ul>\nPM-Wire applications development<\/strong><\/p>\nAML has unique experience in the development of magnet-based systems, including motors and generators. Using proprietary software, the company works directly with the end-use product customers based on three scenarios. The first is the \u2018plug-and-play\u2019 design, which removes conventional magnets and then optimises with PM-Wire magnets with no change to stator design. Next is the optimisation of an existing design, where a machine design is optimised, including stator, and then further optimised with PM-Wire magnets. Finally, there is the generation of a new design, co-developing a new machine optimised with PM-Wire magnets.<\/p>\n\u00a9 shutterstock\/Mimadeo<\/figcaption><\/figure>\nRecycling to magnets<\/h3>\n AML is collaborating with ReElement Technologies (ReElement) \u2013 a company establishing large-scale production capabilities to recycle end-of-life products such as wind turbines, motors and consumer products.<\/p>\n
Extraction of rare earth oxides is needed for the magnet supply chain using a clean and efficient chromatography process. The collaboration will result in production facilities which recycle end-of-life products to manufacturing of PM-Wire magnets for new-life products.<\/p>\n
ReElement has leveraged over 40 years of development and commercial success in the pharmaceutical, insulin and sugar industries. This is not a novel technology but rather a new application of an existing one. Its approach has a proven efficacy on a commercial scale to separate and purify both rare earth elements (REEs) and critical battery minerals to ultra-high purity with high throughput. Through its 40+ years of development and commercial application, ReElement can very accurately dial in mass-balance calculations to adapt very quickly to different feedstocks, achieving targeted yield (greater than 95%) and purity (greater than 99.9%) goals very efficiently.<\/p>\n
Market approach for the REMI supply chain<\/h3>\n AML\u2019s approach to the market is unique. AML focuses on what matters, the magnet-based end-use product like a motor, and optimising the motor for performance and cost. Unlike the conventional approach, PM-Wire provides engineers with a whole new set of knobs to turn in order to optimise motor design. PM-Wire can be used with all existing sintered magnet alloys and opens up new markets for non-sintered. Motor designs can now be fully optimised for performance, including: weight, torque, operating temperature and ease of assembly.<\/p>\n
<\/p>\n
The optimisation process incorporates AML\u2019s unique experience with proprietary software, providing a comprehensive design which considers all aspects of the end-use product design for the magnet supply chain. For example, AML performs design studies which consider a full range of alloy materials ranging from non-rare-earths to non-sintered anisotropic to sintered alloys.<\/p>\n
Market readiness<\/h3>\n AML today is capable of producing non-sintered magnet solutions at full rate to reinvent the magnet supply chain. A state-of-the-art manufacturing line funded by the U.S. Department of Defence was designed, built and commissioned by AML engineers. This robotic line has the capacity to produce 2-6m per minute of PM-Wire magnets. AML is also currently producing sintered PM-Wire magnets at lab-scale and, over the next 12 months, will be establishing full-rate capabilities for sintered magnets.<\/p>\n
AML is supported by the U.S. government and large industry for the collective mission of establishing a sustainable domestic supply chain. Strategic Partners include the U.S Department of Defence, U.S. Department of Energy, U.S. Navy, Oakridge National Laboratory, U.S. Defence & Aerospace Companies, ReElement and more.<\/p>\n
