Study solution of induction motor dynamic braking

The three-phase squirrel-cage induction motors are mostly used in industrial drivers since they are rugged, reliable and economical. The DC bus voltage of the AC drives increases when the motor regenerates. The regenerating energy is usually released in the form of heat. A short mathematical description and the experimental results for different cases of dynamic brake regime are presented in our paper. This solution is recommended for student use and laboratory work to improve understanding of dynamic brake working.
