In rotating motors, the stator or the rotor slots are often assembled in a skew position to reduce the effect of the permeance harmonics
caused by slots. However, an actual skew position in a manufactured motor is not matched precisely to the ideal skew position. Thus, the
effect of the uncertainty of a skew position is investigated in terms of the vibrational characteristic. Then, a space-time kriging surrogate
model is proposed to consider the uncertainty of a skew position in the design stage with the aid of a computer simulation. The proposed
surrogate model handles a time variable having time interval and predicts values between time intervals. Then, the performance of the
proposed model is verified with simulation data and reliability estimated by the proposed model is compared with real data measured
from manufactured motors.
