Project e-MECA targets ultra-compact, high power density electric machines for hybrids; focus on 8-12 kW output
17 January 2012
The e-MECA (electro-Mécanique Embarquée à Compacité Améliorée) project, launched in France in December 2011 and coordinated by Valeo, seeks to develop ultra-compact, high power density solutions for embedded electromechanical systems. The 3-year project will be mainly dedicated to machines such as motor-generators with an output of 8kW to 12kW for mild and full hybrid vehicles.
Supported by €1,497,846 (US$1.9 million) in funding from l’Agence nationale de la recherche (ANR, the national research agency) the partnership brings together two companies (SKF and Valeo), the IFPEn and three laboratories (Satie, Dynfluid and Tempo). The overall project management will be the responsibility of Valeo.
The major research effort is to study the increase in the frequency conversion (rotation speed and number of pole pairs) of electrical machines. The work will focus on the study and development of tools, models and methodologies for the optimization of electrical machines. The project is also intended to reduce the use of expensive materials in order to reduce system costs.
Functional models will be made and tested by the manufacturers. The study of gear suitable for high rotational speeds of the machines considered for each application will be treated in a separate application project.

KSPG already demonstrated a similar compact on-board genset at the 2012 Detroit Auto Show. It is compact enough to install in the spare wheel hole in the trunk. A duplicate unit may not be that bad but is it needed?

Harvey, this seems to be just an electric motor, not any sort of genset.

There are countries where most people do not know the difference between motors and engines and indeed engines are thought to be locomotives. Babbage had a "difference engine" to calculate mathematical functions. As a child, my uncle had an electric engine with a solenoid driving a flywheel with a crank, but it also was an electric motor; an example of a very early switched reluctance motor.
Switched reluctance motors require no exotic materials other than iron and a good conductor for the coils, and some configurations will operate at the fastest speeds. They should be considered for all automobile motors and generators, since they have light weight and very high reliability and efficiency. The best metglasses could be used in them for even higher efficiencies, and there are no conductors in the rotors to waste energy or magnets to waste money. ..HG..

This is, of course, forgetting how cheap and good hydraulic hybrids are. .See Artemis and UPS. ..HG..
