Analysis of squirrel cage induction motors with broken bars and rings

A method is developed for describing the performance of a cage induction mo tor when it is operating under any asymmetrical condition. The system of no nlinear voltage and torque differential equations is analyzed directly with out transformation by using a numerical solution by means of an electronic computer. Both the steady-state and the transient state may be computed. Br oken bars and rings of the cage winding, during operation are examples.
