Factors to Consider When Choosing Variable Frequency Drives.

from a large number of vendors, available are the many choices of the drive. In order to make a good decision when selecting a variable frequency drive, some factors need to be considered. in order to improve the speed of the motor, the variable frequency drive converts the alternate current to direct current. The speed control portion of the drive uses the direct current voltage to create the direct current pulses in varying frequency to drive the output motor. The speed of the motor matters depending upon the number of the poles the motor was designed to operate with. Below are some factors to consider when selecting the right variable frequency drive.

before coming to settle on a certain choice of the variable frequency drive, the loads or the processes planned in your system is the factor to consider. this is due to some loads being hard to start. In order to cover the higher current demands of the hard-to-start loads, the variable frequency drive requires an oversized unit.

The second factor to consider when choosing a good variable frequency drive is the number of motors the drive will control. If the motors to be controlled are more than one the away they start whether sequentially or simultaneously determines the selection of the variable frequency drive. after calculating the total current peak of the worst operating conditions of the loads also helps determine the choice of the variable frequency drive.

when selecting the variable frequency drive the third factor to put into consideration is the quick start or sudden stop of the load. high currents will be required of the variable frequency drive if that will be the case and also an oversized one too. Oversizing the drive will also improve the working of the variable frequency drive.

The range of the motor sizes your process or processes require the variable frequency drive to handle is the fourth factor to consider when choosing variable frequency drive. When choosing the variable frequency drive the range of the motor sizes your process or processes require the variable frequency drive to handle is the fourth factor to put into consideration. Since small motors cannot perform as well as the larger ones, improvements will be required due to the variable frequency drive apparent.

when selecting variable frequency drive the need of procession or drive features is the other to consider. You should know that you can have a drive that trips instantly in an overcurrent condition. To conclude, you are advised to put all the above factors to be considered when choosing a variable frequency drive so as to help you select the better one.
