Abstract
This paper describes the way to estimate the exciting force of the DG motor by measuring the leakage flux. At first, we examined the effective position which measured the leakage flux, because the excitation force of the DC motor is mainly due to the current. Next, we calculated the frequency characteristics of the leakage flux and excitation force and it was confirmed that the equal frequency component appeared. Then, we measured the leakage flux and excitation force at the same time, and compare their level. As the result, the radial exciting force can be estimated to some extent by measuring the leakage flux in symmetrical position and taking the difference of them.
