The landscape of rare earth elements is experiencing a significant transformation driven by the rapid growth of electric vehicle (EV) sales. In 2024, demand for rare earths from EV motors surged to 37 kilotons, marking a substantial 32% increase from the previous year. This trend is expected to continue, with projections indicating that demand will reach 43 kilotons in 2025.
The primary contributors to this rising demand are three critical elements: neodymium, dysprosium, and terbium. These elements are essential for manufacturing the powerful magnets used in electric vehicle motors, notably Permanent Magnet Synchronous Motors (PMSMs) and Axial Flux Motors. Together, these two motor types constituted over 86% of the EV motor market in 2024.
The taxonomy of EV motors includes several types: Permanent Magnet Synchronous Motors, Induction Motors, Electrically Excited Synchronous Motors, and Axial Flux Motors. Despite the variety, it is the PMSMs and Axial Flux Motors that rely heavily on rare earth permanent magnets, underscoring their importance in the transition to electric mobility.
The demand for rare earths is closely tied to the technological preferences in the EV sector. Permanent Magnet Synchronous Motors are favored for their efficiency, high torque output, and compact design, making them the standard in the global market. In contrast, Induction Motors, while viable, are generally less efficient and larger, which detracts from their appeal for widespread EV applications.
The most commonly used magnets in these motors are neodymium-iron-boron (NdFeB) magnets. These magnets often incorporate dysprosium and terbium to enhance their performance at higher operating temperatures.
As the adoption of electric vehicles accelerates, the requirement for rare earth elements in motor manufacturing is anticipated to grow steadily. Even as some automakers explore alternative designs that minimize the use of rare earths, the inherent efficiency benefits of PMSMs position these motors as a continued preference. Consequently, the demand for neodymium, dysprosium, and terbium is expected to remain robust in the coming years.
