Abstract

Manufacturing tolerances as well as measuring errors have a great influence on products designed by optimization technique etc. to improve its characteristics and reduce the cost. Therefore, a tolerance analysis technique is required to find the tolerance band of design variables and estimate the characteristic distribution of the products. In this paper, the authors introduce a stochastic response methodology (SRSM), which treated design variables as random ones. Also, they present a way of the tolerance analysis from electric viewpoint. A BLDC motor is analyzed to verify the application of this method. Finally, the validity of this method is confirmed by obtaining statistically significant results for torque characteristics of the motor.
