Abstract
Discussion around decarbonisation of our society leads to the fact that mobility has become a hotspot that we need to tackle. Hence the electrification of the mobility has been intensified all around the world. For designers, tier 1 and automotive OEMs the question remains which materials to use and which way to go. Different alternative concepts of traction technology exist. While copper appears to be the material of choice for many electrical applications, alternative materials e.g. REE are used as reference in rotors for electric vehicle motors. To provide a good basis for decision making in the automotive industry to support their sustainability goals, the environmental impacts related to the manufacturing process of different types of electric motors (induction machines with copper rotor and also ferrite assisted and pure synchronous reluctance machines) in the typical power range of electric vehicles (75 kW and 200 kW) has been performed. The work was carried out within the EC funded REFREEDRIVE project (refreedrive – Rare Earth Free e-drives featuring low cost manufacturing). This presentation intends to give some key facts which help to answer some of the questions raised by stakeholders on sustainability, while comparing different concepts, the Induction Motors (IM) and the Synchronous Reluctance Motors (SynRel), both in different configurations.
