Current in Broken Squirrel Cage of Induction Machine
The paper deals with the squirrel cage of an induction motor. Faulty connection between the rotor bar and the end-ring has a fundamental effect on the magnitude of the current of an affecting bar and surrounding bars as well. By the matrix equation is solved the current distribution in the damaged bars of a squirrel cage. The thermal dilatation of the bars is also observed. Unsymmetrical thermal stress on the bars causes them to different dilatation and leads to further development of the fault.
