    2. Assessing the environmental impact of AC machines

    This section briefly presents the LCA tool applied to AC machines. The overall ecobalance resulting from an LCA approach applied to the "medium power" range induction motor will be presented according to its type of service: continuous or intermittent. The reference motor considered in this study is assumed to be supplied directly from a balanced three-phase network. This motor, which has an aluminum rotor cage, is characterized by the following nominal values: 10 kW; 400 V; 50 Hz; 21 A; 1,400 rpm; cos j = 0.81.

    2.1 Life cycle analysis of an asynchronous machine

    • Applying an LCA-type environmental study to an electric motor therefore begins with the design phase. The motor is assembled from a set of elaborate materials (steel, copper,...
