Dynamic Braking Resistors
Dynamic braking resistors:
The DC bus voltage level of an AC drive increases while the motor is re-generating (i.e. ramping to a stop). Dynamic braking resistors provide a means of rapidly stopping a rotating motor and load while maintaining an acceptable bus voltage level.
The kinetic energy stored in the spinning mass is converted into electrical energy and quickly dissipated as heat through a resistor.
