Abstract: | Significant number of research articles on axial uniform mixed air gap eccentricity detection methods in three phase squirrel cage induction motor are reported in literature. Most often, machines suffer from non uniform axial air gap eccentricity. In this paper, a study conducted on a three phase squirrel cage induction motor suffering from inclined mixed air gap eccentricity is presented and a new parameter is introduced to detect the inclined eccentricity fault. Experiments were conducted on 3 phase squirrel cage induction motor to show the impact of inclined mixed air gap eccentricity on dq components of stator currents. To validate the experimental results, mathematical expressions and modeling and simulation results are presented. The paper concludes with a note that an eccentricity detection unit with dq components of stator currents in synchronous reference frame as detection parameters can be embedded in the controller circuit to monitor the health of the machine. � 2014 IEEE. |
