Dynamic Braking Resistor: A Core Product Offering
One of our flagship products is the Dynamic Braking Resistor (DBR) — a robust, high-wattage resistive device designed to safely dissipate excess energy generated during motor deceleration in Variable Frequency Drive (VFD) systems.
By converting surplus electrical energy into heat, DBRs protect motor drives from overvoltage conditions and minimize mechanical wear.
Typical applications of our dynamic braking resistors include cranes, conveyors, elevators, pumps, and a variety of industrial drive systems, where smooth and controlled stopping is critical.
What is the Role of a Dynamic Braking Resistor?
- Energy Absorption During Braking: When a motor slows down, it acts as a generator, feeding power back into the drive’s DC link. Without a means to dissipate this energy, overvoltage and potential damage may occur. The dynamic braking resistor diverts and safely dissipates this energy as heat.
- Enabling Controlled and Faster Stopping: DBRs facilitate smooth deceleration without relying on mechanical brakes, thereby reducing mechanical wear and extending system life.
- Protecting Against Overvoltage: By managing voltage spikes during braking, DBRs prevent drive trips and safeguard critical components.

Frequently Asked Questions (FAQs)
Q1: What is a dynamic braking resistor?
A dynamic braking resistor is a high-power resistor that converts excess braking energy into heat, protecting motor drives from overvoltage during deceleration.
Q2: How does dynamic braking differ from regenerative braking?
Dynamic braking dissipates energy as heat, while regenerative braking feeds energy back into the electrical grid. Khushi specializes in dynamic braking solutions, ideal for applications where grid feedback is not practical.
Q3: How do I select the right dynamic braking resistor?
Selection depends on motor/DC link voltage, load inertia, braking duty cycle (usually under 10%), resistor power rating, resistance value, and cooling requirements.
Q4: Can dynamic braking resistors fail?
Yes, failures can occur due to undersized resistors, incorrect settings, poor quality, or improper installation. Khushi offers expert design support and uses premium materials to minimize these risks.
Q5: What maintenance is required?
Maintenance is minimal — regular cleaning and ensuring adequate heat dissipation is recommended, along with periodic checks of connections and insulation.
