Abstract :
A method is developed for describing the performance of a cage induction motor when it is operating under any asymmetrical conditions. The system of nonlinear voltage and torque differential equations is approached directly without transformation by using a numerical solution by means of a computer. Both the steady-state and the transient state may be approached. As examples broken bars and rings of the cage winding, during operation are given
