How Does a Braking Resistor Work?

During motor deceleration, regenerative energy generated by the motor can increase the DC bus voltage of a VFD system. A braking resistor absorbs this excess energy and converts it into heat, helping prevent over voltage faults and ensuring controlled motor deceleration and preventing VFD over voltage protection trips
