Hello guys, in this zip file, you will find the Matlab Simulink model on DC Dynamic-based braking of the Induction motor.

 

An induction motor can be stopped using DC dynamic braking by disconnecting the power source and delivering a DC voltage to the motor’s windings. This voltage produces a magnetic field that resists the motor’s rotation, slowing it down until it finally stops.

In applications like elevators, cranes, and trains where the motor has a high moment of inertia or a significant mass, DC dynamic braking is frequently used. To avoid accidents or equipment damage in these situations, it’s crucial to rapidly and safely bring the motor to a stop.

Typically, a DC power source or a rectifier that changes the AC voltage from the motor’s windings into DC voltage provides the DC voltage needed for dynamic braking. The motor’s windings are then exposed to the DC voltage through a switch or relay.

One benefit of DC dynamic braking is that it can quickly and completely halt the motor while also offering high deceleration rates. It can also be utilized to regulate the motor’s speed while decelerating.

DC dynamic braking does have some restrictions, though. If the braking process is not properly controlled, the DC voltage might build heat in the motor’s windings, which can harm the motor or shorten its lifespan. Moreover, the DC voltage may introduce electrical noise or interference into the system, which may have an impact on nearby devices or components.

Overall, DC dynamic braking is a useful technique for stopping induction motors in applications involving large mass or inertia. To ensure secure and dependable operation, it needs careful design and management.
