Abstract:

The system boundaries and scopes were defined after presenting the life cycle process model of electromechanical products, and the key assessment issues were analyzed. Then, the environment-impact indicators system of electromechanical products was found considering the design factors, including technique attributes,economic attributes and environmental attributes. The quantification methods of assessment factors were discussed in detail.Finally,  the rationality of indicators system and the feasibility of quantification methods were proved by its application on a pint-sized electromotor.

Key words: life cycle assessment (LCA); indicators system; quantification methods; electromechanical products
