The principle of tolerance design is receiving increased research focus to determine the optimal tradeoff between manufacturing price and quality. However, current tolerance designs are not suitable for products such as electromagnetic devices that require high reliability, i.e. a very small failure rate. In this paper, new tolerance design problem with high reliability is formulated. As an alternative, a reliability-based tolerance design is proposed in order to guarantee the reliability of the products while maximizing manufacturing tolerances. The proposed method quantifies the reliability using reliability analysis, which is reflected in the tolerance design. To validate the proposed method, our tolerance design is applied to two examples: a magnetic circuit and an IPM motor that contains tolerances of PM.
