Scania genomgår nu en transformation från att vara en leverantör av lastbilar, bussar och motorer till en leverantör av kompletta och hållbara transportlösningar.
Scania is going through a transformation to become the provider of complete and sustainable transport solutions.
The fabrication of sustainable and environmentally friendly products and solutions often require the development of new technical methods. As an example, the electrical machine is intended to replace or be combined with combustion engines in the near future. Electrical machines have a long history in trains and generators, and the way different materials behave and interact in those applications are well documented. However, these systems can not be directly transferred to the anticipated transport solutions that Scania intends to deliver to the end customer in the future.
The electrical machines are formed by conducting metals, such as copper wires, and insulation materials, mainly polymer-based. Specifically, the copper wire must be covered with an insulation material, called strand insulator, such as polyamideimine (PAI), polyesterimides (PEI) or polyetheretherketone (PEEK). Nowadays, the strand insulation is enameled by running the wire through a varnish (solvent and resin) multiple times. However, this process comes with some disadvantages such as:
In the last years, a significant amount of research in electrodeposition of resins onto different metals has been technologically advanced. Using this method, the geometries of the copper wire are only limited by the size of the reaction vessel, obtaining a controlled, regular, and pin hole-free and potentially thinner insulator layer. In this thesis, an electrodeposition system involving copper wires and commercially available resins, is going to be applied, and the resulting material will be characterized and tested in order to assess the physical and chemical properties of the coating.
This Master’s thesis will be done in the department of Materials Technology for Electrification, Electronics and Transmission at Scania R&D in Södertälje, Sweden.
