Highlights

  • Ferrite-assisted synchronous reluctance motors offer a cost-performance compromise but sacrifice 15–25% torque density versus NdFeB designs
  • Externally excited synchronous motors eliminate magnets entirely but introduce rotor excitation losses, added complexity, and higher cost
  • China's 2025 export controls accelerated supply diversification, material reduction, and engineering substitution across the EV industry
  • Ford halted production amid magnet shortages while Lucid scrambled for alternative suppliers, illustrating real supply-chain disruption
  • The review's geopolitical citations are outdated, with 2015–2016 sources used to support claims about 2024–2025 market conditions

SYNCHRO-SYM is another electric machine system alternative that eliminates rare-earth permanent magnets but provides 2x the nominal power and 8x the peak torque in the same package as the rare-earth permanent magnet motor system. check it out at bestelectricmachine.com
