What is dynamic braking?

Dynamic braking is one method used to dissipate excess energy generated when the load controlled by a variable frequency drive (VFD) is quickly slowed or stopped.

How do dynamic braking resistors work?

Dynamic braking resistors absorb excess energy produced in the motor as the drive provides braking torque to stop the motor.

Why is a braking resistor used with a VFD?

A braking resistor supports variable frequency drives by providing a path for the energy produced with braking to dissipate. The braking resistor allows the VFD to brake the motor faster, safer and more effectively without over voltage tripping the VFD.

Can dynamic braking resistors be used with all VFDs?

Yes, our resistors are compatible with a wide range of VFD brands and types, but proper sizing and installation guidance are essential for optimal performance.

Do dynamic braking resistors improve motor lifespan?

Absolutely. By reducing overvoltage and limiting thermal stress, dynamic braking resistors help extend the life of your motors and prevent premature failures.

What industries benefit most from VFD braking resistors?

Industries with conveyors, cranes, elevators, machine tools, and packaging systems benefit significantly from dynamic braking solutions due to frequent deceleration and high-inertia loads.
