The demand for fuel efficiency, pollution reduction and creature comforts is forcing the automotive companies, to evaluate alternate electrical systems. The most popular choice to date is the introduction of a 42-Volt system, which uses 3 batteries in tandem with 14 volts of peak power. The 42-Volt electrical system is being introduced in automobiles to provide the extra power needed for various electromagnetic devices. This paper discusses the opportunity offered by the 42 Volt 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.
