Regardless of your doubts it is a viable option that should be considered.

You are talking to people you do not know on the internet, please give the simplest and most correct answer possible.


"Most Correct"????

That is strictly a matter of opinion.

Either replacing the motor or producing a third phase are 'correct' answers and I bet there are other correct options as well.

Neither I, this site, nor you I am sure wants to be sued for giving bad or hard to follow advice.


No, but advising to change the motor is no different from advising to produce a third phase. Either method can be done wrong and result in injury.

In this case the answer is simple and obvious, unless the motor is part of a larger and listed assembly then junk and replace it.


That is one opinion, John is also entitled to his.

In general I am a keep it simple guy and think VFDs are being overused but that is just my humble opinion. smile
