Abstract EN
The purpose of this paper is to investigate the effect of the axial air-gap eccentricity (AAGE) on the electromagnetic characters such as the axial unbalanced magnetic pull (UMP) and the electromagnetic torque (EMT).
Firstly, the theoretical model of AAGE is set up, and the formulas of the axial UMP and EMT are deduced.
Then the simulation study of a SDF-9 nonsalient pole synchronous generator is taken with Ansoft Maxwell to calculate the detailed axial UMPs and EMTs under normal condition and five AAGE conditions, respectively, with 2 mm to 10 mm rotor displacements.
It is shown that an apparent axial UMP will be produced due to AAGE, while EMT and the phase current will be decreased.
In addition, the magnetic flux density (MFD) on the stator end and the rotor end, which are more far from the center position of the stator core in the axial direction, will be decreased, while the MFD on the other ends will be generally kept stable.
As AAGE develops, the axial UMP will be increased, while EMT and the phase current will be decreased.
The proposed work offers a reference for the fault diagnosis and monitoring on AAGE.
