Hmm, let's see....

Motors can be damaged if they're put on top of a stick of dynamyte, or if they're dumped in water, or if they're thrown in a very hot fire, dropped from a very high point, or if they're smashed between rocks....There are a lot of ways an AC motor can get damaged. Not quite sure what you're asking here....

I don;t think you got the right answers. I think the correct answer is that you need a motor with the correct IP rating. IP67 means they are immersible. See https://www.google.com/url?sa=t&rct...YGoojJUaQEZKKaw&bvm=bv.73231344,d.cWc&cad=rja

I don't think he asked the right question - it was vague beyond belief!

From your name, I know where you are from. Your problem is Low Voltage and Phase Failure. Low voltage can lead to the motor drawing excess current and result in a burnout. So can phase failure for a 3 phase motor. Low Voltage Cutoff and Phase Failure Cutoff relays is a solution. This will also mean that your motors are likely to remain idle for a major part of the day! Other solutions are too expensive for the farmer to afford.
Replace the Motor with a Diesel Engine as almost all farmers do.
