The effect of deep-bar properties when assessing reswitching transients in squirrel cage induction motors

Abstract

When analyzing transient torques the motor generalized equations are usually solved for various time lags between break and remake of the supply. It is shown that when dealing with motors having deep bar properties, it is important to include the deep-bar characteristics when doing simulations. The results show that when the changes in the bar parameters with speed are included, then the transient torques predicted may be significantly larger.<>
