The motor vehicle of the longer term has to fulfill basic specifications: the super-efficient use of power and gear and the ultra-safe transportation of individuals and items either positive factors are more and more enabled by means of shrewdpermanent, adaptive and context conscious info and conversation applied sciences (ICT), electric or digital parts and platforms instead of completely via the mechanical technique of vintage automobile engineering. the main complex instance of this development is the electrified motor vehicle combining an entire electrical powertrain with thoroughly digital controls like clever strength and effort managers, steer-by-wire applied sciences and clever networking features. it's been the undertaking of the foreign discussion board on complicated Microsystems for car purposes (AMAA) for greater than twelve years now to observe paradigm shifts and to debate their technological implications at an early level. accordingly, the subject of the AMAA 2010 is “Smart platforms for eco-friendly vehicles and secure Mobility”. This ebook includes peer-reviewed convention papers awarded on the convention by means of specialists of significant businesses and top educational associations. They document on ongoing learn and novel advancements within the box of ICT, parts and platforms permitting the auto and street delivery of the long run. a selected concentration is on simple applied sciences and complicated functions of electrified and electrical automobiles, highway and passenger defense, motive force information, site visitors administration and powertrain potency. because of this wide assurance of themes concerning sustainability of the car either the AMAA occasion and this publication serve the spreading of information generated within the framework of the ecu eco-friendly automobiles Initiative. additional info is on the market on www.amaa.de.

3 BLDC Water pump with integrated electronics Summary The need for improved fuel economy is generating a large need for cost effect and reliable solutions to drive electric motors under very challenging conditions. With its smaller raw material cost and its inherent higher reliability brushless motors are the obvious way of the future. The today’s capabilities of sensorless control bring the future already a significant step closer. New developments in hard- and software will continue to increase performance and reduce cost.

In the proposed method, the six step inverter modulation is adopted and only the torque is controlled acting on stator voltage space vector position, since the amplitude is fixed and equal to the maximum deliverable. In this configuration, some drawbacks are unfortunately present : Managing a current limit protection is quite complicated. The inverter switching frequency is related to the regulator torque hysteresis bandwidth and is not constant in the operating range. Is not possible to control easily the flux at zero speed with zero torque reference.
