Variable frequency drives are known to play a vital role in reducing energy consumption, lengthening a motor life as well as improve control. When it comes to choosing the right VFD, most companies find the process to be challenging. The following are the steps companies need to follow when searching for the right variable frequency drives.
One of the critical considerations to getting the right variable frequency drives involves determining if the drive you want is right for your needs. When you install a variable frequency drive, it will regulate the speed of your three-phase inductor motor. When you use a variable frequency drive, it will provide non-emergency start and stop control, deceleration, acceleration, and overload protection. Another beauty of having a VFD installed is that it will reduce the amount of motor inrush current by accelerating the motor steadily.
Besides, it is a good idea to know why you need a VFD. Here are some of the reasons why companies may prefer installing variable frequency drives, these include saving energy, adjusting torque, controlling starting current, controlling stopping and for reverse operations. It is worth noting that VFDs are the best option for centrifugal fans and pump loads since they help in cutting energy consumption.
Before you can spend money on a variable frequency drive, it is best to choose the right size for the load. It is a good idea to consider the operating profile of the load, the drive will carry when choosing the VFD size. You also need to consider the peak current of the machine you want to buy. It is worth noting that that the peak drive of the VFD you want to buy needs to be higher when you want to use it under worst operating conditions. If you want to read the motor FLA, you need to check its nameplate.
Checking the braking requirements of the system you want to buy is also vital. Having a dynamic braking resistor is vital for VFDs used for applications with heavy loads that need to be quickly decelerated.
The roadmap to getting the variable frequency drive involves paying attention to the reputation of the manufacturer. Though knowing the company to work with may seem difficult, you need to focus on the duration the manufacturer has been making the drives.
The internet is a good source of information of the best manufacturers of variable frequency drives. One of the reasons why you need to search online is that you will get many manufacturers that make the best variable frequency drives. In addition, you need to check the credentials of the companies. This guide is vital for companies looking for the best variable frequency drives.
