WebFeb 26, 2024 · Plugging can be more harsh on electrical and mechanical components, but it provides a faster stop than dynamic braking methods. Plugging — sometimes referred to as “reverse current braking” — is possible on both DC motors and AC induction motors. For DC motors, plugging is achieved by reversing the polarity of the armature voltage. WebFeb 24, 2012 · Dynamic Braking. Another method of reversing the direction of torque and braking the motor is dynamic braking. In this method of braking the motor which is at a running condition is disconnected from the source and connected across a resistance. When the motor is disconnected from the source, the rotor keeps rotating due to inertia and it …
