source:AUTO FUTURESGlobal automotive and industrial supplier Schaeffler has signed a five-year contract with Norwegian company REEtec AS for the purchase of rare earth oxides. The aim is to make electric motors for hybrid modules, hybrid transmissions and all-electric axle drives even more sustainable. Permanent magnets manufactured using rare earth metals, like neodymium, produce optimum magnetic flux in electric motors.In future, the German company will procure these metals from REEtec AS, which uses a sustainable production process.The partnership will begin in 2024.REEtec has been sep...

source:Electronic DesignHigh power density is an important characteristic in most motors, even in a tiny motor with a high-power-output capability. A high-power-density motor (HPDM) is one that has a high ratio of power/volume.The smallest motors can even have a high power output. HPDMs are low-speed, high-torque motors. These motors are usually lightweight, small, and have large amounts of torque and lower cogging torque. Cogging torque is defined as the torque necessary to overcome an opposing torque that’s created by the magnetic attractive force between the rotor magnets and the stator iro...

source:solarQuotesPowerful permanent magnets made from Rare Earth Elements (REEs) give us cheaper, lighter and more efficient generators and motors for wind turbines and electric cars.Australia is the world’s 4th largest producer with 8% of REE production. But China is the rare earth element elephant, with 60% of the world’s supply. Their share of production used to be up around 95%, but after trying to hike the price in 2009 other countries — including Australia — started mining for REE. Because China’s attempt to raise prices failed, you might think people would feel relaxed...

source:UPIBANGOR, Maine, March 22 (UPI) -- To go green -- to build a carbon-neutral economy and achieve net-zero emissions -- the United States will need a lot more rare-earth elements, experts say.REEs, sometimes called rare-earth metals, are used to make a variety of electronics, from iPhones to MRI machines. They're also vital to produce many of the most important green energy technologies, including solar arrays, wind turbines and electric car batteries.As a result of the growing consumer electronics market and expected green energy transition, the White House predicts the demand for c...
