Life Cycle Assessment Comparison of Synchronous Motor and Permanent Magnet Synchronous Motor

This paper deals with environmental impact indicators identification and evaluation of electric motors used for electric vehicle propulsion. As it is known, the transport sector is the most polluting one in the world, and through the top alternatives is the electrification of road transport. Thus, the purpose of this study is to assess the potential environmental impacts of vehicle’s manufacturing phase by using life cycle assessment from the design stage. By conducting a life cycle analysis, it is desired to find a better environmental performance of cars ‘production. The focus being on the use of new materials or renewable energy sources. The main purpose of the study involves a comparative environmental analysis of electric traction motors. For this study have been considered two types of motors: synchronous motor and permanent magnet synchronous motor. The electric traction machines will be analyzed using a software specialized in life cycle assessment studies. By the end of the study it will be possible to show which of the two machines has a negative influence on the environment, including resource depletion, eco-toxicity, climate change, etc.
