RESUMO

A thermal and electrical dynamic mathematical model for squirrel cage induction motors is presented. The electrical model is described by Park s equations and the torque equation, while the thermal model is described by a system of four first order diferential equations that represent the motor heat transfer processo The model presented can be used to determine thermal and electrical peformance for any operation condition. However, it is suitable mainly for machines operating under contiunously transient condition. The presented mathematical model also incorporate variation of rotor winding electrical parameters due to skin effect
