NdFeB knowledge
Trace magnet quantities, installation locations and sources
Twelve tables classify models, applications, masses, installation locations and sources. Each figure remains linked to its system boundary; further recycling standards are available through the appropriate technical link.
12 data tables
Review models, masses and evidence individually
Reading guide & evidence classes
System boundaries, evidence classes A-M to X and rules for using the values correctly.
→02Top 10 by reference magnet mass
Ranking, values, basis, direct sources and evidence status.
→03Literature-based factors & outliers
Reference factors used, with conflicting values clearly separated.
→04Wind turbine models with NdFeB
Documented topologies, calculated values and model-specific limitations.
→05Wind turbines without NdFeB in the main generator
Clearly magnet-free generator architectures and system boundaries.
→06Electric vehicles with NdFeB
Models, motors, generations and measured or secondary-source values.
→07Electric vehicles without NdFeB in the traction motor
Only clearly magnet-free motor architectures, linked to the relevant variant.
→08Hybrid vehicle teardowns
Hybrid-vehicle teardowns: dismantling values for motor and generator assemblies, including system boundaries, installation locations, source evidence and material classification relevant to purchasing.
→09Robotics & servo drives
Models, published data gaps and generic literature values.
→10Other devices & original applications
Pumps, HVAC, pedelecs, motors and other magnet sources.
→11Studies and sources
Government, manufacturer, laboratory and peer-reviewed sources.
→12Contradictions, gaps & limitations
Open questions, conflicting values, required primary evidence and limitations on the technically sound use of the NdFeB data.
