Improvement of an automotive alternator using the Experimental Design Method

This paper deals with the use of the experimental design method for the study of electromechanical problems. This methodology is here applied to the case of a wound rotor synchronous machine (WRSM) used as a car generator. The experimental design method is a technique based on statistical concepts and aims at establishing the links existing between input variables (factors) and output ones (responses). Factors are typically dimensions and physical properties of the machine, while responses correspond to ldquointerestingrdquo variables which are generally to be improved.
