Workpackage

An integrated system requires to combine different disciplines of control and operation, materials, and sustainable manufacturing process, cooling and thermal management, mission profile analysis and electric machinery and therefore multidisciplinary models are established.

The methodology can be verified by prototype testing for the most energy- and material-efficient HSM-drive system in maximally one megawatt power range. The novelty in this research is to combine electric motor design and power electronics with control technology design aspects, giving skills of both to all DCs. In addition to the scientific aim, the DN target is to enhance the quality of the doctoral training practices through the training programme.

One objective is to use the developed high-fidelity modelling methods to find design solutions for a high specific power (power-to-weight-ratio) drive system required in mobile applications. (WP4) This research branch is needed in mobile applications in order to diminish energy consumption and increase reliability and decrease the vehicle weight. To reach high-specific power level better cooling methods are needed, which are heat-pipes, direct liquid cooling, phase-change, and other novel method.

WP5 Sustainability aims for Development of process chains for functional integration and performance improvement of EV motor components. With Precision Engineering design principles and Precision Manufacturing solutions it will be achieved small tolerances, small air gaps, higher torque, and lower losses.
