Trend of the hybrid vehicle and expectation to the magnetic materials

Abstract

Environmental issues are greatly affected by the automobiles. One of the solutions is to introduce Green Cars into the market. Currently, Hybrid vehicles are green cars with good environmental performance and are expected to be popularized.HVs should have motor, inverter and batteries in addition to the conventional ICE vehicle units. Therefore, being compact, light-weighted and low cost are highly required. Specific output of PM in current HVs has improved about 3.5 times more than a DC motor in early EV. As of motor size, if 700MGOe from MEXT's* prospect will be implemented, it is possible to reduce the motor size by 30 to 40% with only material change. It is quite safe to say that HVs' revolution with overwhelming fuel economy, environmental performance and quietness is achieved by materials improvement of units such as motor. *Ministry of Education, Culture, Sports, Science and Technology.
