DFSS, a design approach leveraging various methodologies, proves particularly effective for making incremental improvements during the redesign phase, with a focus on Critical to Quality parameters (CTQs). The paper concentrates on implementing DFSS concepts and methodologies to elevate the quality and performance of alternators. Computer Fluid Dynamics (CFD) is employed to evaluate temperature and mechanical performance, both crucial CTQs for alternators. The initial step involves identifying the key components contributing to the analyzed parameters. Subsequently, the variables of each component are categorized as critical or non-critical for further examination through a design for experiment approach. Numerical experiments are conducted to attain the optimal solution for the CTQs. The application of this methodology successfully reduces the temperature from the initial design to an optimized one, with a notable decrease of 16 Kelvin in the average temperature of the rotor, while maintaining mechanical losses within an acceptable range. In conclusion, the application of DFSS proves instrumental in improving product quality incrementally, without requiring substantial investments, in a systematic manner.
