During the rheostatic braking of a dc motor

WebDynamic braking, also called rheostatic braking, allows you to break a motor by reversing the torque’s direction. . With your brake, you essentially disconnect your running motor from its power source. Your motor’s rotor will then begin to rotate due to inactivity, thus functioning as a generator. WebDuring the Dynamic or rheostatic braking the kinetic energy of the motor is converted into electrical energy. This energy is dissipated in resistive elements. The rate of dissipation …
