Electric vehicles: motors and magnets?
This data-file assesses electric vehicle magnets, permanent magnets and the use of Rare Earth materials such as neodymium (NdFeB). 80-90% of recent EVs have used Rare Earth permanent magnets, averaging 1.5 kg per vehicle, or 7.5g/kW of drive-train power, across the data-file. But the numbers vary vastly. From 0-4 kg per vehicle. 20 vehicles from…

Magnets and permanent magnets: company screen?
The global magnet industry is fragmented across hundreds of suppliers, including 800 in Asia-Pacific. The total market is worth $20bn pa. The purpose of this data-file is to highlight a dozen leading magnet companies, including producers of permanent magnets, Rare Earth magnets (e.g., NdFeB), ferrites and other magnetic components.

Wind turbine generators: DFIGs or Rare Earth magnets?
Wind turbines can use doubly fed induction generators (DFIGs) or permanent magnet synchronous generators (PMSGs) based around Rare Earth metals. This data-file captures the trends in DFIGs vs PMSGs over time by tabulating 40 examples, as turbines have grown larger, and different wind turbine manufacturers have adopted different strategies.

Magnets and energy: fundamental attraction?
Electric currents create magnetic fields. Moving magnets induce electric currents. These principles underpin 95% of global electricity, while 50% of wind turbines and 95% of electric vehicles use permanent magnets with Rare Earth metals. This 15-page overview of magnets explains key magnet concepts and controversies for the energy transition.

Commodity prices: metals, materials and chemicals?
Annual commodity prices are tabulated in this database for 70 materials commodities; covering steel prices, other metal prices, chemicals prices, polymer prices, all with data going back to 2012. 2022 was a record year for commodities. The average material commodity traded 25% above its 10-year average and 60% of all material commodities made ten-year highs.

Uranium production: by company and by country?
Global uranium production is broken down by company and by country in this data-file, which also screens 20 of the most noteworthy companies in uranium mining, the reserves, production and operational details. This matters as another contracting cycle is underway in the uranium industry, due to rising power demand, next-gen nuclear, but also supply disruptions…

MOSFETs: energy use and power loss calculator?
MOSFETs are fast-acting digital switches, used to transform electricity, across new energies and digital devices. MOSFET power losses are built up from first principles in this data-file, averaging 2% per MOSFET, with a range of 1-10% depending on voltage, switching, on resistance, operating temperature and reverse recovery charge.

Electric vehicle: battery life?
Electric vehicle battery life will realistically need to reach 1,500 cycles for the average passenger vehicle, 2,000-3,000 cycles after reflecting a margin of safety for real-world statistical distributions, and 3,000-6,000 cycles for higher-use commercial vehicles. This means lithium ion batteries may be harder to displace with novel chemistries?
