Germany successfully developed without the use of rare earth metals MotorBrain motor prototype

Infineon Technologies announced that German researchers show will change the future of the electric car motor prototype : small size, light weight , and can efficiently . It is jointly developed and developed by the German partner in Europe "MotorBrain" research projects, including Infineon , Siemens, lightweight School of Engineering and Polymer Technology Dresden University of Technology and ZF AG . Motor prototype "new energy vehicle technology development ," the German federal government booth ( Hall 27 , H51 booth ) on debut.

MotorBrain prototype is a highly integrated motors , electric vehicle powertrain integrated the most important component. The researchers successfully designed a highly compact motor , its size is only the beginning of the year MotorBrain Project ( 2011 ) model designed for three-quarters . Now on display fits easily into conventional motor prototype laptop bag . More importantly , it is lighter than the previous . By integrating the motor , gears and inverters , MotorBrain partners the powertrain weight significantly reduced by nearly 15% , increased from 90 kg to 77 kg. This will reduce the size and weight of the electric car owners benefit future : electric cars lighter , help to improve the utilization of battery power , thus ensuring a greater distance than the conventional electric vehicle . With 60 kilowatts ( about 80 horsepower ) MotorBrain motor in the car relative to the existing electric vehicle ( one charge an average mileage of about 150 kilometers ) , can travel more than 30-40 km .

In addition , partners have also successfully developed without the use of rare earth metals MotorBrain motor prototype - currently , rare earth metals is an important factor leading to the high price of hybrid cars . Is an important part of any rare earth permanent magnet motor . This magnet can produce particularly strong constant magnetic field. The stronger the magnetic field , the higher the performance of the motor . However , to obtain a rare earth metal is not only very complicated , but also pollute the environment. In addition, the high price of rare earth metals , large fluctuations . Therefore , MotorBrain motor selection of readily available and affordable ferrite magnets. Ferrite magnet with respect to rare earth magnet performance is slightly lower, but through the use of specially developed high- speed rotor MotorBrain compensate .

About the European research project "MotorBrain"

Infineon led by a total of 30 partners from nine European countries involved in the research MotorBrain projects aimed at improving mileage and safety of electric vehicles , while reducing dependence on rare earth metals . R & D team to develop and manufacture covers all relevant areas of electric vehicles. Team members include universities, research institutes, semiconductor manufacturers , motor manufacturers, automotive suppliers and major vehicle manufacturers . MotorBrain project started in the fall of 2011 . In the distance the project deadline ( October 2014 ) in the first half , research partners had exhibited unused highly integrated rare earth motors. In the rest of the time ( until October 2014 ) , they can verify and prove their research results. MotorBrain project budget of about 36 million euros, which makes it one of the largest research project in the field of electric vehicles in Europe . Project funding comes from the major companies and state-funded , such as the German Federal Ministry of Education and Research and the European Union institutions ENIAC.

Compact energy-efficient motors:
prototype demonstration in 2014 of new energy vehicle technology exhibition
As Hanover Industrial Fair ( Hannover, Germany in 2014, April 7 to 11 ) part , MotorBrain projects will be on display in the new energy vehicle technology exhibition German federal government booth ( Hall 27 , Booth No. H51 ) . In "Our electric vehicle development road " as the theme , the German federal government unveiled several typical research project involving the manufacture of electric vehicles , charging , drive and energy , and other major core areas . MotorBrain motor is " energy-efficient battery and powertrain systems " and " manufacturing " section on display at the third stop .

In addition to the demo booth in the new energy vehicle technology forum ( April 9, 2014 at 3:30 pm ) , the Infineon ReinerJohn entitled " security, independence and energy efficiency of electric vehicles ," the speech, introduced the core research MotorBrain motor.
