“…where Y is a response parameter; β, the regression coefficient; d ν , the number of factors (13 in this case), x i , the i th input factor; and X Ci , the normalized (coded) value of the i th factor. Factors may be normalized as shown in (5). X Ci = 0 represents the specified values of the factors with zero manufacturing error, and β 0 is a representation of response parameter in this reference situation.…”

In the process of designing an electric machine, the systematic study of tolerances for the design variables and material properties is of the utmost importance. This paper proposes a method by which possible variations of the design variables and material properties can be distinguished. The design of experiments (DOE) technique, open-circuit and shortcircuit tests, with minimum instrumentation requirements, have been employed. Virtual tests are conducted based on the recently approved IEEE 1812 testing guide for PM synchronous machines. As a case study, a 100 hp 16-pole 18-slot spoke-type PM machine is discussed. It is shown that variation in magnet remanence, steel grade, as well as dimensional tolerances, may be identified. The ratings and magnetic loading of the machine plays a critical role in identifying manufacturing tolerances.

“…The different design steps, often aided by automatic tools, rarely take into account Manufacturing Tolerances (MTs) or deviations of material properties [6], [7], [8]. Therefore, the manufactured machine may behave differently from the ideal design obtained through the design process.…”

The improvement of the robustness of the performance of electrical machines in presence of neglected features, such as manufacturing tolerances and deviations in material properties and parameters, is increasingly demanded. The available optimization procedures do not account for manufacturing tolerances, leaving the decision process incomplete. The paper proposes a methodology for the selection of the more robust design towards manufacturing tolerances among the best candidates, detected by an optimization procedure. Statistical tools for tolerance analysis and worst-case analysis are discussed and adopted for the scope. The proposed methodology is used to select a robust design with respect to torque ripple deviations due to geometric tolerances in the laminations of a Synchronous Reluctance Motor with fluid shaped barriers. The statistical performance analysis and the worst-case analysis provide an estimation of the performance deterioration in the presence of the tolerances in the manufacturing process.
