Dear Engineers,

 

How to start a 220KW ac induction motor by using AC DRIVES TO REDUCE POWER CONSUMPTION?

1.Are they any AC drives?please mention their price and specifications?


Dear Rafi ;

 

Certainly, there's a Variable Speed Drive for even more than 220kW, I will mention below the references for ” Schneider Electric ” :

 

ATV61HC22N4 : the transient torque for this VSD is ” 120 … 130% “ of the nominal torque for 60 seconds

ATV71HC25N4 : the transiant torque for this VSD is ” 170% “ of the nominal torque for 60 seconds, and ” 220% “ for 2 seconds

 

So, depending on your application if you need standard or high torque you can do the choice. Noting that for each one there's many options that you can add.

 

For the unit price, you can ask the Schneider Electric office or any distributors for them in your country.

 

Rem. : if you need more information about them please send me an e-mail at  hagersg@aloola.sy
