Proposals are expected to address all the following:

• Increasing primary efficiency, in particular by widening the high efficiency area and compactness, for example through topology or operational improvements, inclusion of increased features in integrated solutions, analysis of performance aspects over the machine-in-system life-cycle.
• Demonstrate the following specific targets(further details in the work program p.362).
• Increase high system voltages offering new opportunities for readdressing the current versus voltage trade-offs, throughout the vehicle systems and in aspects of the recharging infrastructure, duly considering potential impacts.
• Guarantee the heat rejection of high energy density motors through multi-physics models in order an optimal design (use of rare resources, reduction in losses, high efficiency).
• Novel manufacturing process supporting increased integration, enabling, amongst other things, improved thermal control.
• The use of alternative architectures and materials to the currently used rare earths-based magnets and configurations. Recyclability plus life-cycle environmental impact aspects need to be considered, aiming at the best compromise with other performance parameters to reach the stated outcomes. If composite reinforced materials (CRM) are included in the design, the development of processes for the economic recycling of at least 60% of any rare materials needs to be included: only this additional work will justify the use of up to EUR 2 million of the expected EU contribution.
• The proposed concepts should consider the motor (integration of electronics, excluding their development at component level), and integration of any related transmission.
