Let's start with what variable frequency drives are used for...

Variable frequency drives are used for electronic speed control of AC induction motors. You might also refer to them as adjustable speed drives, variable speed drives, AC drives, microdrives or inverters.

The second question is who should be using variable frequency drives?
Marshall Wolf Automation can make this easy to determine by asking you the following questions:

• Do you have AC industrial electric motors in your facility?
• Are you looking to lengthen the life of these motors by running them at speeds that are designed for variable loads?
• Are you trying to save on energy costs? 

If you said yes to the above questions then you should install variable frequency drives on your AC induction motors. 

 

Variable speed AC drives save energy costs, extend the life of your motor and take the burden off other power components. Many utilities are even offering rebates for using variable frequency drives.
