In Mechanical braking, the motor is brought to rest by means of friction in the rotating shaft. It is accomplished by adding weight to the shaft through the brake drum. WebDynamic Braking Application Summary Dynamic braking is one method used to dissipate excess energy generated when the load controlled by an adjustable frequency drive (AFD) is quickly slowed or stopped. When a motor is quickly slowed down, it becomes a generator, feeding energy back into the AFD. The energy that is fed back increases the DC lyric god will make a way
