Stability improvement of fail-safe dynamic brake for three phase induction motor

Abstract

This paper presents the method of how to brake the three-phase induction motor by using the capacitor without the required external energy. Tnstead, the temporary electrical energy stored in the rotor due to the time constant which is related to the kinetic energy left in the rotor at the moment is used with the capacitor to exite enough energy to stop itself. This paper shows the analysis of how to brake the motor as mentioned both statically in terms of the stability of braking including the improvement of the stability and dynamically by computer simulation in different conditions in addition to the experimental results for a better design and practical application of the three-phase induction motor braking.
