Braking Resistors: High-performance for VFD Applications

Electricity is a strange energy that powers and fuels countless machines and gadgets daily. It runs everything from our lights to our refrigerators. The VFD is the electrical machine. It helps manage the speed of electric motors. We use these motors for many things in our life; from the elevators that are used to move people, escalators that help each other to move up and down for each floor, conveyor belts, and many more. But what you may not know is that VFDs require a special component known as a braking resistor. This stage is crucial for smooth functioning. Let’s explore how this part is so fundamental.

The Importance of Braking Resistors for VFDs

A variable frequency drive (VFD) is a type of motor controller that drive (VFD) is a type of motor controller that controls the speed & torque of an electric motor. In some cases as the motor slows down or almost stops, it can even deliver electricity back to the VFD. That return flow of electricity is called regenerative energy. Although it seems quite practical, it can actually lead to some issues for the VFD. This added energy can result in the motor stopping too fast, which can be hazardous, or it can damage the VFD itself. That’s where braking resistors are needed. These resistor inverter special components capture the zero point energy that the generator produces and aid in the smooth and safe vessel deceleration. In this way, they prevent both the motor and the VFD from being damaged.

This Is How Braking Resistors Allow VFDs To Operate Efficiently

For example, brakes resistors, such as a SANYU one, are useful as they not only protect the VFD but make it run more effectively as well. When the motors draw the additional power, they convert that energy into heat. Although heat is a by-product of this energy process, the VFD does not require this heat so the braking resistor dissipates it. By allowing correct heat to escape from the VFD housing, this digital frequency converter has a cooling effect that keeps the VFD at a lower temperature, which is critical in terms of its performance and service life. And a cooler running VFD has a shot of being efficient for the long-haul.

Advantages of High-Performance Braking Resistors

These high-performance braking resistors can dissipate a very high amount of extra energy without getting too hot. Why is this so important Well, if a resistor gets too hot, it can fail or even break. These vfd resistor unique resistors are manufactured with modern materials designed to quickly transfer heat away from the path, which makes them incredibly efficient. More than the regular braking resistors, they can dissipate more energy and hence would have a longer life. You won’t need to replace them as frequently, saving you time and money over the long term. Selecting high-performance braking resistors, such as SANYU braking resistors, is a property of intelligent choice for anyone who wants to be able to use his or her VFD for as long possible.

How to Select the Correct Braking Resistor for Your Variable Frequency Drive

Choosing the correct braking resistor for your VFD can be a bit of a conundrum, but it’s vital to get right. You will have to consider a lot of things. The type of motor you have, for starters. One kind of resistor might be needed for one motor, while another one for another motor. Now, take a look at the VFD size. A larger VFD may require a larger braking resistor. Also consider how often your application needs to restart. If it powers on and off multiple times in a short span, you may need a more robust braking resistor. Lastly, ensure that the braking resistor is considered suitable for the VFD. This includes ensuring that the voltage and capacity of the resistor matches the VFD needs. SANYU provides a large variety of types of braking resistors, and is ready to give you recommendations to obtain the highest performance for your VFD.

This is Why Good Braking Resistors Matter

The type of braking resistors you invest in has significant ramifications on the efficiency of your VFD which is why it is important to make the right decision. Braking resistor cost is very low compared to what you can save when a proper braking resistor configuration can be performed. So, there is loss of power output to the motor when the speed of the motor reduces due to excessive energy absorption beyond the limits. These are just a few of the things you can do to help your equipment be more effective and dependable.

And thus, braking resistors are extremely vital to safely and efficiently operating VFDs. The VFD operates effectively and protects the motor from damage, in this context, they play a key role. However, investing in high-quality braking resistors from SANYU can provide numerous long-term advantages that make it worth the investment. Choosing the appropriate braking resistor for your VFD application can allow your equipment to operate more efficiently and have a longer life span.
