How can burn three phase ac motor?

Answer 1

You need to ensure that each line conductor is correctly identified. If you replace them in the wrong sequence, then the new machine will run backwards when you energise it! It may be necessary to use a phase-sequence meter to confirm the phase-rotation before restoring supply to the new motor.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

Answer 2

how can burn three phase motor in single phase

A motor burns due to continuous over load or short circuit with in the winding. Water entry, exposure to moisture, bearing failure, over load - burn the motor.

Answer 3

All you have to do is couple the motor to the generator. The motors output RPM should be at 1800 RPM to match the generator. The generator's rotation needs to be at this speed to generate at 60 HZ. But now comes the question, if you have three phase power already why not just install a transformer to get to the usable voltage that you need. From the transformer's secondary you can either draw the three phase voltage you need or just pick up any two legs from the three phase secondary for a single phase voltage that you need.
