Electrical systems transfer electricity which is mostly produced and consumed by rotating electrical machines. Further, the use of electric and hybrid electric drivelines in both passenger and heavy vehicles is now commonplace and with a continuously growing market share. At the same time, increased computational power and novel control algorithms enable opportunities to reduce energy consumption and/or improving various performance metrics of electric drives. Electrical machines and electric drives are therefore a vital part of the future electrical ecosystem in the global quest towards solutions to environmental challenges.The activities encompass design and analysis of novel electric machinery and electric drives for traction applications as well as corresponding auxiliaries. In recent years, focus has been put on modular converter and machine concepts in order to realize compact integrated electric drives. Further, design of electric machinery taking production aspects into account and the interaction between battery systems and power electronic loads are presently being investigated.
The 1931 Bugatti Royale Kellner Coupe was recorded because most costly car ever. It was sold for $8,700,000 in 1987. Meanwhile, the Bugatti type 41, also referred to as Bugatti Royale, is now one of the rarest cars on the globe. Bugatti produced only 6 from originally planned 25, among them only 3 could find their buyers. However, these cars are certainly not indexed by top rarest and expensive cars on earth because they are certainly not available in the market nowadays. Following are 10 priciest and rarest cars on the market.
