This paper examines a study of an unexpected cogging torque due to the manufacturing tolerances. During the manufacturing, to reduce the cogging torque, various design techniques can be chosen. However, some techniques, which are effective cogging torque reduction methods, can become ineffective. Also, if the manufacturing tolerances exist, they can cause an increase in the cogging torque magnitude. In this paper, the influence of manufacturing defects on the cogging torque is analyzed. For this purpose, the finite-element (FE) analyses are utilized and validated by the experimental measurements.
