42 Volt Architecture on Powder Metallurgy - Opportunities

The 42-Volt electrical system is being introduced in automobiles to provide the extra power needed for various electromagnetic devices. These paper discuses the opportunity offered by the 42Volt for powder metal parts and the challenges. Major opportunities are in motors. A brief discussion of motors and the performance requirements for the magnetic core material used is included. Brushless motor design can benefit the most from insulated iron powder compacts because of the design simplicity of powder metal parts and three dimensional flux capability which is most beneficial in rotating devices.(P/M stands for powder metallurgy and not permanent magnets)
