Applications of 100W Wire Wound Resistor
Why Use a 100W wirewound Resistor?
During motor deceleration, the motor can operate as a generator and return energy to the VFD DC bus. If this regenerative energy is not properly dissipated, the DC bus voltage may rise and trigger overvoltage protection or reduce braking performance.
A VFD braking resistor provides a controlled path to convert this excess energy into heat, helping the drive achieve faster and more stable motor deceleration. This 100W VFD braking resistor is suitable for light-duty braking applications where compact size, reliable heat dissipation, and stable resistance are important.
As a Wire Wound Braking Resistor, it can be used as a Motor Braking Resistor or Dynamic Braking Resistor in AC/DC motor drive systems. The aluminum housing helps dissipate heat, while customizable resistance values allow the resistor to be matched to different VFD and motor requirements.
Typical applications include AC Motor Braking Resistor systems, VFD motor drives, industrial automation, and equipment requiring controlled regenerative energy dissipation.
