Study on Optimal Dynamic Braking Resistor of Induction Motor

Abstract:

In order to discuss the transient process of induction motors dynamic braking,analysis the impact of the brake resistance on the time, and then choose the best resistance.In Matlab / Simulink environment,based on motor simulation model,by repeatedly adjusting the rotor resistor, their impact on motor speed during braking time can be visually observed.By using the least squares method in Matlab, each discrete points of the resistor and the corresponding braking time can be fitted into continuous curve, resulting in the optimum braking resistor under the shortest brake time. With the optimum load resistance in the rotor, the motor brake fastest and more stable without fluctuations,and provide the theoretical guidance for other motor control and engineering.
