As Richard has kindly pointed out you are seemingly lacking in knowledge of key thingd which will allow you to calculate this, I ask if this project is real world or theoretical?. You can't simply convert the KW rating of a motor using ohms law as it seems you are doing, you cant simply google cable sizes off the internet as these are just distance per csa of cable and load related.... you need to apply many factors such as installation method, cable type, grouping, temp etc etc . Google is a wonderful tool but these tables are a guide for current carrying capacity after you have applied all relevant de-rating factors and not for allowing you to calculate a cable size by using basic ohms law and picking from a table, it doesn't work like that.... you need to get an electrician or electrical engineer to overview the project and to correctly calculate the cable size. As you are not UK based our own guidelines, tabulated values etc may differ as well as regulations so even with all the relevant info supplied we would only be able to give you a answer based on our BS standards which may contravene your own local regulations.
Don't take this the wrong way but from the general response and initial posting its clear you are not educated and competent to do this and to be honest we don't really run a free 'do all the calculations' for me service, we are here to aid those who just need a light nudge or small correction not for those who are clearly delving into things they have no basic understanding of.
