Analysis of squirrel cage induction motors with broken bars and rings

A method is developed for describing the performance of a cage induction motor when it is operating under any asymmetrical condition. The system of nonlinear voltage and torque differential equations is analyzed directly without transformation by using a numerical solution by means of an electronic...

Description
Summary:A method is developed for describing the performance of a cage induction motor when it is operating under any asymmetrical condition. The system of nonlinear voltage and torque differential equations is analyzed directly without transformation by using a numerical solution by means of an electronic computer. Both the steady-state and the transient state may be computed. Broken bars and rings of the cage winding, during operation are examples.
