The State Statistical Office lists approximately 84,000 employees in
more than 300 firms in Baden-Württemberg in the area of electrical
equipment; this currently also includes the production of electric
motors [State Statistical Office Baden-Württemberg (2011)]. Thus
there is great potential for extending new business segments and
thus value creation in this area.
ELECTRIC MACHINES
In addition to Daimler AG, Bosch, is also active in almost all areas
associated with electrification of the drivetrain. Moreover, Bosch
and Daimler AG have founded the joint venture, electromobility-
motive GmbH, for the manufacturing and sales of electric motors
[Robert Bosch (2011a)].
Further, SEW-EURODRIVE GmbH & Co. KG in Bruchsal is involved
with propulsion system issues. In early 2011, together with Brose
Fahrzeugteile GmbH & Co. KG, the firm founded the company Bro-
se-SEW Elektromobilitäts GmbH & Co. KG, that markets propulsion
and charging systems for electric vehicles and hybrid vehicles
[Brose (2011)].
There is also a collaboration between Aradex AG in Lorch and ate
GmbH in Leutkirch, which together develop and market the VEC-
TOPOWER electric propulsion system [Vectopower (2011)]. Other
companies are active in the area of propulsion technology, such
as Schopf, AMK automotive GmbH, and Ricardo AG.
In the area of research on alternative propulsion concepts, the KIT
and the University of Stuttgart, the DLR with the Institute of Vehicle
Concepts, as well as the universities of Esslingen, Ulm, and Karls-
ruhe, must be cited. Moreover there are collaborations between
industry and research. In this regard, the founding of „Projekthaus
e-drive“ should be mentioned, within which Daimler AG and the
KIT started a research cooperation in the area of electric pro-
pulsion in 2008 [Idw (2008)]. In addition to the power electronics,
control and regulating technology sectors, electric machines, and
electric energy storage devices should also be researched uni-
formly, „under one roof“.
Moreover, in 2011 the doctoral program, „Projekthaus e-drive“,
came into being through Daimler and the Stuttgart supplier, Behr
GmbH, through which an initial ten doctoral candidates are being
supported for four years [KIT (2011a)].
POWER ELECTRONICS
Companies from the power electronics sector include the large
enterprises such as Bosch, Daimler AG and Porsche AG for ex-
ample, as well as the AMK Group headquartered in Kirchheim/
Teck, Lauer & Weiss GmbH from Fellbach and Bertrand AG, head-
quartered in Ehningen.
A cooperation of industry and research/teaching that is unique in
Germany is the Robert Bosch Center for Power Electronics that
was opened in June 2011; it was founded and co-financed by
Bosch. At both locations of Reutlingen University and the Univer-
sity of Stuttgart, in coming years approx. 30 million euros will be
invested in extending the infrastructure, professorships, and new
courses of study. In October 2010, the master’s degree program in
power electronics and microelectronics was extended to include
the focus areas of optical and power electronics and information
technology. The bachelor’s degree program in mechatronics adds
a new focus area. In addition, a new part-time master’s degree
program, nano electronics and optoelectronics & power electro-
nics, has been developed [RB Center (2011)]. Further, the KIT, Ess-
lingen University and the DLR are pursuing research in the area of
power electronics.
»The fact that EM-motive, the new joint venture of Daimler
and Bosch for traction electric motors, will settle its develop-
ment in Baden-Württemberg must be welcomed. However, the
downside for the regional economy is that production of these
e-machines for pure electric vehicles will not also take place in
Baden-Württemberg.«
Dr. Jürgen Dispan, Project Director and scientific employee,
IMU Institute
»I think that production of the power electronics is predestined
for Baden-Württemberg.«
Jürgen Jost, Division Director, Research & Development,
Dürr Systems GmbH
