WebAsked By : Monica Horton. Dynamic 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. WebJul 11, 2011 · To figure out braking behavior, simply use the model with a resistor equal to the motor's DC resistance when stalled; the inductance can probably be ignored except when one is trying to rapidly switch the motor current on and off (e.g. with a PWM drive).
