Factors to Consider When Choosing a Variable Frequency Drive
At a time when energy costs have been extremely high, people are looking for more energy efficient solutions. If you consult a technician or an engineer, most of them are going to advise you to use a variable frequency drive. While a variable frequency drive is a relatively simple device, finding the right one is not as easy. The fact that variable frequency drives are available in many different sizes and designs means that design is suitable for a different purpose.
When purchasing a variable frequency drive, many people really look beyond the horsepower. One variable frequency drive is not the same to another and you should, therefore, consider several factors when choosing one. This is especially important for people who do not want to test their choice on black when buying a variable frequency drive for a specific application. This website provides you with all you need to know about variable frequency drives and how you can find the right one for your application without breaking a sweat.
You should only start looking for a suitable variable frequency drive once you know the horsepower of the load. This, however, does not change the fact that it is essential to size a variable frequency drive with the full load amps of the motors upon which you intend to use the variable frequency drive. Without proper knowledge of your load, it is going to be difficult for you to find a variable frequency drive that can deliver to your needs.
When buying a variable frequency drive, another thing you need to consider is the voltage. It is important that you match the voltage of the variable frequency drive and moto to the voltage you currently have on site for a three-phase input which makes it relatively easy. The classifications for low-voltage applications are region-specific and those in your area may be different to those in another part. If you are dealing with medium voltage or other applications, it is best if you work with an application specialist or engineer to determine your needs. If you are dealing with a single phase input, you may need to consider several things.
Another important part of your decision when selecting a variable frequency drive is the speed range of the motors. When running a motor, the speed should always be more than twenty percent of the maximum speed allowed as it is specified by the manufacturer. Running a motor at a lower speed may cause overheating especially if you do not use any auxiliary motor cooling. It is also important that you remain careful when over speeding a motor. Any speeds you push your motor to should be covered by the manufacturer’s warranty; otherwise, it may not be a good idea.
