AC motors

I started a project in which I want to use an Arduino board to protect 230v AC motor from under and over voltage. Please show me circuit diagram and explain the code used.It's really urgent please contact me as soon as possible.

Do not cross-post. Other thread removed.

AC motor? That's not enough information, I know of half a dozen types in common use.

Why does a motor need protection from under and over voltage? Seems an odd thing to me. This is a mains
powered motor?

Lets think this through a bit longer. By the time you have decided the voltage is over or under the limit, that voltage has already gone to the motor. I don't think this is going to work. Perhaps I don't understand what you are really trying to accomplish/

Yes , more info needed - type of motor, size , 3ph ?

What’s wrong with conventional protection systems - thermal trip
and fuses connected to a suitable contractor ? The thermal trip “models” heat build up to protect the motor .
There are also methods using a temperature sensor embedded in windings to sense over heating .
