Performance is a key requirement of electric motors and generators which are used in many applications, most importantly for electric vehicles, and is paramount in all sectors of motor sports: from KERS in Formula 1 to hybrid solutions in Le Mans cars. The main goals are to push performance and innovation to their limits, targets which have been publicly achieved on the race track in recent years.
In precise terms, the aim is to achieve maximum performance at minimum weight - i.e., to optimise power density. Ultimately, the central technological requirements remain virtually identical, despite variations in the economic framework conditions. Innovative optimised drive technologies are the key pillars of eMobility.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
