Reliable Braking Resistors for Safe and Efficient Motor Control
Khushi Control System is a trusted Dynamic Braking Resistor Supplier in Odisha, offering application-specific braking resistor solutions for AC drives, variable frequency drives (VFDs), cranes, elevators, hoists and industrial motor-control systems.
Our dynamic braking resistors help dissipate regenerative energy produced during motor deceleration.
This enables faster stopping, protects the drive from overvoltage and improves operational safety in demanding industrial applications.
As a trusted brand partner of Lauritz Knudsen and Inovance, GTAKE and a dealer of INVT VFD products, we deliver advanced automation and motor control solutions tailored to diverse industrial requirements.
We are based in Ahmedabad, Gujarat, India.

Why Are Dynamic Braking Resistors Used?
When an electric motor slows down, it can behave like a generator and return energy to the VFD’s DC bus. If this excess energy is not controlled, it may cause an overvoltage trip or damage sensitive drive components.
A dynamic braking resistor converts this regenerated electrical energy into heat and safely dissipates it. It supports:
- Faster and more controlled motor deceleration
- Reduced VFD overvoltage trips
- Improved braking performance
- Better protection for drives and motors
- Stable operation during frequent start-stop cycles
- Enhanced safety in high-inertia applications
- Reduced mechanical stress on equipment

Frequently Asked Questions
What is a dynamic braking resistor?
A dynamic braking resistor is an electrical resistor connected to a drive system through a braking unit or chopper.
Does every VFD require a braking resistor?
No. A braking resistor is generally required when an application needs rapid deceleration, frequent stopping or control of a high-inertia or overhauling load. Compatibility depends on the VFD and its braking arrangement.
How is the correct braking resistor selected?
The resistor is selected using the VFD specifications, minimum permissible resistance, motor rating, braking time, load inertia and duty cycle. An incorrect resistance or wattage can cause ineffective braking, overheating or drive damage.
Can Khushi Control System supply custom braking resistors?
Custom configurations can be provided according to the required resistance, power, duty cycle, mounting arrangement and enclosure specifications, subject to technical evaluation.
