Abstract:
With the growing demand for Battery-driven Electric Vehicles and a high competition for high-performance and cost-effective propulsion system and electrical machines, development of new insulation systems that can address demanding requirements of new generation electrical machines is of vital importance. Any developed insulation system needs to address the high stresses due to the high switching frequency inverters, as well as aggressive cooling system and mechanical stresses applied to the insulation components during the production process, while keeping the insulation dimensions minimum in order to enable high efficiencies in electrical machines.
In this webinar, an innovative conductor insulation will be presented which well addresses the above requirements with the minimum thicknesses required. Additionally, an advanced test and verification process is carried out in order to verify application of the developed conductor insulation in the electrical machines used in battery electric vehicles. The developed insulation system is also tested in the wire production process and feasibility of the developed material is verified not only in terms of performance, but also in terms of producibility in high-volume.
