Reuse and Recycle Strategies of Rare Earth Permanent ...
Rare earth PM AC machines are widely used in industry nowadays. Their high efficiency as well as high energy density brings unparalleled superiority. On the one hand, the renewable energy markets are estimated to gain explosive growth in the next decades, such as Hybrid (H) and pure Electrical Vehicles (EV), Escooter, wind turbines, electrified marines and aircrafts etc. However, on the other ...
Investigation of a less rareearth permanentmagnet ...
· Due to the rising price of rareearth materials, permanentmagnet (PM) machines in different appliions have a trend of reducing the use of rareearth materials. Since ironcore poles replace half of PM poles in the consequent pole (CP) rotor, the PM machine with CP rotor can be a promising candidate for less rareearth PM machine. Additionally, the investigation of CP rotor in .
Performance Comparison Between SwitchingFlux and IPM ...
· Performance Comparison Between SwitchingFlux and IPM Machines With RareEarth and Ferrite PMs Abstract: Switchingflux permanent magnet (PM) machines compared with interior PM machines are presented to be interestingsolutions in terms of torque per volume density, compactness, active material layout, and cooling capability. The flux linkage is bidirectional, and the voltage is almost ...

HyProMag is also a partner in the Innovate UK grant funded project, "RareEarth Recycling for EMachines" ("RaRE"), together with University of Birmingham, Advanced Electric Machines Research Limited, Bentley Motors Limited, Intelligent Lifecycle Solutions Limited and Unipart Powertrain Appliions Limited, which for the first time will establish an end to end supply chain to ...
Making rare earth materials as sustainable as possible ...
· Rare earth magnets are increasing in demand as we shift to a zerocarbon economy, and electric vehicles especially use a lot of magnets. Currently, less than 1% of these magnets are actually recycled, so as the demand for them increases, as does the scale of extraction and processing of the rare earth materials, which is creating huge environmental issues.

In highfield machines employing rareearth magnets the effect of saturation is significant, and therefore appropriate modifiion to the classic tworeaction theory has to be considered to ...
Rareearth Magnet Recycling
Rare Earth Magnet Recovery Machine for HDDs The electric motors in HDDs contain rareearth magnets. These are called voice coil motors (VCMs). Fig. 2 shows the process used to separate and recover the rareearth magnets. While development of an HDD dismantler(1) that removes VCMs from HDDs and demagnetizes them has already been completed, Hitachi also developed new recovery machines .
Rare earth metals see new medical uses
· Rare earth elements consist of yttrium and the 15 lanthanide elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium). Scandium is also found in most rare earth element deposits and is sometimes classified among them. Though called "rare" because they are seldom .

· Improved density of 〈 c + a 〉 disloions is indispensable for enhancing the ductility of Mg alloys. More 〈 c + a 〉 disloions can be activated by reducing the basal stacking fault energies (SFEs) through the addition of rareearth (RE) elements, but they are rare and costly. Therefore, it is worthwhile to develop a screening criterion of RE elements free Mg alloys with low SFEs ...
