Tips to Help You When Looking for Variable Frequency Drives.

many drive choices are available from a large number of venders around you. when it comes to choosing a variable frequency drive , several decisions have to make so as to end up owning the best one. 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. depending on the number of poles the motor was designed to operate with, the speed of the motor matters. so as to help you come to a good choice of the variable frequency drive, below are some factors outlined for you.

The demands of the loads or the processes in your planned system is a factor to consider when it comes to selecting the variable frequency drive. With some loads being hard to start, this comes at hand. In order to cover the higher current demands of the hard-to-start loads, the variable frequency drive requires an oversized unit.

when it comes to the selection of the variable frequency drive, the other factor to be considered 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. the loads under the worst operating conditions also help to determine the kind of variable frequency drive to select which is concluded after calculating the total peak of currents in the motor.

when selecting the variable frequency drive the third factor to put into consideration is the quick start or sudden stop of the load. an oversize drive will be needed due to the high currents required if that will be the case. to make the drive’s size bigger will improve the working of the variable frequency drive.

The fourth factor to be put into consideration when choosing a variable frequency drive is the range of the motor sizes your process or processes require the variable frequency drive to handle. Small motors are not as efficient as the larger motors so improvements due to the variable frequency drive will be 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. In conclusion, you should look at the above factors in order to help you make a better choice of variable frequency drive.
