Factors to Consider When Choosing a Variable Frequency Drive
The search for more energy efficient solutions has never been more frantic as it is now given that the energy costs are at an all-time high. Buying variable frequency drives has become one of the common things among many people. Finding the right variable frequency drive can be very challenging. Not every variable frequency Drive is suited for your purpose since they come in many different sizes and designs.
Most people only choose a variable frequency drive based on the horsepower. However, there are many other factors you need to consider since not all variable frequency drives are equal. 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. If you are having a hard time finding the right variable frequency drive for your application, the guide below provides you with all the key factors you need to consider when purchasing one to make things easier.
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. If you do not know the horsepower of the load, finding a variable frequency drive that can comfortably and all your needs is going to prove to be quite a challenge.
You also need to look at the voltage before you make any decision when choosing a variable frequency drive. it is easier if you are working with a three-phase input since all you have to do is match the voltage of the variable frequency drive and motor to your available for research on-site. The classifications for low-voltage applications are region-specific and those in your area may be different to those in another part. A medium voltage that other applications may require the input of application specialists or engineers to determine the requirements. If you are dealing with a single phase input, you may need to consider several things.
Finding the right variable frequency Drive becomes a lot more easier when you consider the speed range of the motor you are using.It is recommended that you run the motor at more than twenty percent of the specified maximum speed allowed. Unless you use any form of auxiliary motor cooling, your motor is going to offer it if it is run at lower speeds. If you have to over speed a motor, you need to take care. Any speeds you push your motor to should be covered by the manufacturer’s warranty; otherwise, it may not be a good idea.
