Analysis of Constant Losses of Three-Phase Squirrel Cage Induction Motor with Different Types of Eccentricity Under No Load Operating Condition

This research investigates the core loss of a 5 HP three-phase squirrel cage induction motor across different levels of three types of eccentricities (static, dynamic, and mixed) utilizing Ansys Maxwell software. The simulation outcomes for core losses are compared with analytical core loss values. No load and loss separation tests conducted under healthy conditions and at 12% static, 12% dynamic, and 12% mixed eccentricities to determine constant loss and isolate the core loss from constant loss. Furthermore, the simulation and analytical findings are compared with experimental results, particularly at a rotor eccentricity of 12%.
