Question

How is dynamic braking for direct current motors accomplished?

Expert Solution

Step 1

$\Rightarrow$ Dynamic braking for a DC motor is accomplished by permitting power to remain connected to the shunt field when the motor is stopped, and reconnecting the armature to a high wattage resistor

$\Rightarrow$ The resistor may actually be more than one resistor depending on motor size, length of braking time, and armature current. The braking time can be controlled by adjusting the resistance value. If current remains connected to the shunt field, the pole pieces retain their magnetism. Connecting a resistance across the armature terminals causes the motor to become a generator.
