PASSENGER business case 4: automotive headlamp systems

Modern automotive headlamp systems rely on compact, precise actuator motors to enable adaptive beam control, height adjustment, and dynamic lighting functions. These electromechanical systems are essential for safety, comfort, and energy efficiency in both conventional and electric vehicles.
Currently, most headlamp actuators use NdFeB-based permanent magnets to achieve the required torque and responsiveness within a small motor footprint. However, this dependence on Critical Raw Materials (CRMs) such as neodymium (Nd) and  Dysprosium (Dy) exposes manufacturers to price volatility and supply risk.
The PASSENGER project develops Rare Earth-free permanent magnets based on Manganese–Aluminium–Carbon (MnAlC) and Strontium Ferrite (Sr-ferrite), offering sustainable, cost-stable, and EU-manufactured alternatives. This business case explores their integration in automotive headlamp actuators, assessing technical feasibility, economic potential, and environmental advantages.
