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.

Would you like assistance in finding out which of our high performance AC
 drives would be best for your application? As always we offer free in-house technical support.

Our Recent E-Newsletter: Hitachii WJ200 Variable Frequency Drives

Wednesday, November 30, 2011 by Beckie Bordenaro

Why you should take a look at the Hitachi WJ200 
variable frequency drive:

  • Bhitachi wj200uilt-in PLC
  • Encoder input (pulse input) for position control
  • Runs permanent magnet or induction motors
  • 200% plus starting torque 
  • ISO13849 rated safe stop circuit
  • Even better - you get all of these features for the price of a standard variable frequency drive!

Simple Positioning Control

The built-in PLC and encoder input (pulse input) give you simple positioning control.

 

This is a huge advantage over the Mitsubishi D700 which does not offer a built-in PLC. One more thing... they only offer 5 digital inputs, our Hitachi WJ200 high performance AC drives has 7!

One Inverter For Two Types of Motors

The Hitachi WJ200 variable frequency drive can drive both induction (IM) motors and permanent (PM) magnet motors. For more information on this feature please contact one of our in-house engineers through sales@wolfautomation.com.

 

Are You Exporting?

If you are exporting to Europe you will love the ISO13849 compliant safe stop circuit! This is a great feature that the Allen Bradley PowerFlex 4 does not offer!

 

This also allows you to eliminate the contactor for e-stop functions.

Marshall Wolf Automation is your authorized industrial automation distributor for the full line of Hitachi variable frequency drives!
