1397 Open Chassis Dynamic Brake 1397-DB- A001L — A150L B003L — B300L Dynamic Brake Kit Operation Dynamic braking slows down a rotating DC motor and its load. It is an uncontrolled process. During dynamic braking, the motor armature is disconnected from the drive. A resistor is placed across the motor’s rotating armature (now acting as a generator), and the resulting current causes braking torque in the motor.
