many drive choices are available from a large number of venders around you. In order to make a good decision when selecting a variable frequency drive, some factors need to be considered. The alternate current is converted to the direct current in order to improve the speed of the motor by the variable frequency drive. in varying the frequency to drive the output motor, the speed control portion of the drive uses the direct current voltage to create the direct current pulses. depending on the number of poles the motor was designed to operate with, the speed of the motor matters. In order to help you be able to make the right decision in choosing the variable frequency drive, below are some factors to consider.
One of the many factors to consider when making a choice on matter concerning a good variable frequency drive is the demands of the loads or processes in your planned system. 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 number of motors the drive will control is the second factor needed to be considered when selecting the variable frequency drive. the way the motors are going to be started determines the selection of the variable frequency drive, whether sequentially or simultaneously. by calculating the total peak currents of all the motor loads under the worst operating conditions also helps determine the kind of the variable frequency drive to be selected.
Requirement of a quick start or emergency stop of the load is the other factor that you need to consider when selecting a variable frequency drive. an oversize drive will be needed due to the high currents required if that will be the case. To improve the variable frequency drive, to oversize the drive may be necessary.
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. the variation of performance between the small and the improvement of the large motor will be needed on the variable frequency drive.
The need for equipment or drive features that will ensure the continuity of the procession is another factor to put into consideration when choosing a variable frequency drive. 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.
