What is Braking Resistor? Working, Application
The electrical energy generated by a motor or machine is dissipated as heat by the braking resistor when it is decelerated or stopped. The resistor is connected in parallel with the motor and absorbs the energy, which is converted into heat due to the resistance. The dissipated heat enables smooth deceleration or stopping of the motor.
When and How Should I Select a Braking Resistor?
The braking resistor will dissipate the excess energy by converting it to heat across a resistor element. Finally, if the regenerated energy from the motor is continuous or the duty is high, then it may be more beneficial to use a regen unit rather than a braking resistor. This will still protect the VFD from hardware damage and nuisance …
