The industry places increased importance on carbon reduction. Many are focused on lowering the fuel consumption of electrical machines, however, carbon emissions from the acquisition of raw materials and the energy consumption of manufacturing processes also contribute significantly. Therefore, a carbon emission analysis model is particularly necessary for electrical machines. This paper presents an evaluation method for the carbon emissions of the production of industrial synchronous generator. The results concluded can be used to reduce the carbon emission of electrical machines, material waste and energy consumption, moreover, identify a detailed investigation of the impact between raw material acquisition, manufacturing process planning and carbon emissions.
