Why Braking Resistor Used In Vfd at John Froehlich blog

Why Braking Resistor Used In Vfd. Selection of the appropriate braking resistor: Braking resistors are used for applications where the motor speed exceeds the speed that is set by the variable frequency drive (vfd) or when fast deceleration is required. Braking resistors work in vfd applications by slowing the motor to an exact speed set by the drive. Dynamic braking resistors (dbr) are used with variable frequency drives (vfds) to dissipate regenerated power that is produced in the motor as the drive provides braking torque. Braking resistors within vfd (variable frequency drive) will enhance the capacity of braking torque, generating more controlled & faster braking. This resistor will dissipate regenerated power to maintain the bus voltage from exceeding the speed limit of the drive. Braking resistors act as a release valve for excess energy, providing a pathway for controlled dissipation. Let’s explore the steps involved: When vfd drives a motor, the motor acts as a generator when the motor’s actual speed is more than the vfd frequency. Before you embark on connecting a braking resistor to your vfd, it’s crucial to choose the right one. The generated energy dissipates in the resistor ( dynamic braking resistor), leading to the motor’s braking.
