Abstract
In this paper the fundamental development of a new process
chain for manufacturing of round wire windings will be
presented. The development was carried out inside the project
NeWwire which was a cooperation of several universities, the
companies Volkswagen, Essex and Aumann. The project was
publicly funded by the Federal Ministry of Education and
Research (BMBF) in Germany. The basic approach of the new
winding technology was motivated by the fact, that even with
today's automated processes for the production of distributed
round wire windings, a superior winding can still be created by
a skilled worker. Based on the manual process and the need for
automation, an alternative series of process steps was developed,
tested with functional samples and implemented in machine
prototypes for further development.

Abstract
The optimization of the effective winding in the
stator to increase the performance represents a special
challenge. The aim is to accommodate as many copper
conductors as possible in the narrow stator groove in a
reproducible manner, with a high quality and short production
times without damaging the enameled copper wire.
Therefore, the compact winding process, based on the
manual trickle winding process and complying with these
requirements, is introduced in this paper. The basic ideas of this
novel method are described in detail. The developed compact
winding process enables layer winding with higher fill factors in
the stator grooves of the windings and new production steps like
compressing and cementing of wires for contributed windings.
In addition, this method was successfully implemented into a
test stand. Finally, further potential investigations are discussed
and with reference to released publications.

Abstract
The trend of globalization has led to a structural change in the sales and procurement markets of manufacturing companies in recent decades. In order not to be left behind by this change, companies have internationalized their production structures. Global production networks with diverse supply and service interdependencies are the result. However, the management of global production networks is highly complex. Key performance indicator (KPI) networks already exist at the corporate level and site level to support the management of complex systems. However, such KPI networks are not yet available to support the management of entire production networks. In this article, a KPI network for global production networks is presented, which links the key figures of the site level and the corporate level. By integrating both levels into a comprehensive KPI network, cause and effect relationship between the production-related KPIs and the strategic KPIs of a corporate strategy become transparent. To this end, this KPI network is integrated into a Performance Measurement and Management (PMM) methodology. This methodology consists of three phases: performance planning, performance improvement, and performance review. For testing the practical suitability, the PMM methodology is applied to the production network of an automotive supplier using a simulation model to estimate the effects of proposed improvement actions of the methodology.
