Recommended Posts

Hi All,


We have to buy a 1.5 MW, 1500 rpm Induction Motor for one of our applications. We have the option of an option of buying either an Air Cooled or a Water Cooled Motor. The atmosphere contains conductive dust .


What is the preferred type of motor in this case ? What are the advantages and disadvantages of one type over the other, in general ?

Dear easyser,


in general, there is the possibility to write a book on this argument.

Please explain your application, your needs, your availability of clean/industrial water, your installation type, etc. Give us as more info as possible, to get good suggestions.

There are also motors with liquid-to-air heat exchangers, do you considered them?

MV or LV motor?

Fixed frequency or variable frequency?
