The motor has to be a dual voltage motor for this operation to happen. This will be a six coil motor. Each motor coil will be rated for a 220 volt drop across it. For the high voltage connection the motor's coils are connected in series between L1 and L2, L2 and L3, and L3 and L1. For the low voltage connection the motor's coils are connected in parallel between L1 and L2, L2 and L3, and L3 and L1.

The generator should be about ¾ hp.
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
You can not change it. 440 volt is by design. However you run it with 220 single phase supply, but it would run far lower power.
Use a transformer.
Yes by using a 3-phase transformer. The size depends on how much power has to be converted.

If the output of a generator is increased from 220 volts to 400 volts, it could be due to an adjustment of the generator's voltage regulator or the generator being overloaded. This change in voltage could be dangerous for equipment designed to operate at lower voltages and could potentially lead to damage. It is important to ensure that the voltage output of a generator remains within safe limits for the equipment being powered.
Yes.
If the motor wire numbers are L1, L2 and L3, it is not a single phase motor. It is a three phase motor. Also for future reference, a 220 volt single phase motor does not use a neutral.
You Don't. 440volt 3-phase is actually 480 volts, taking a single phase gives 277Volts single phase. To get single phase 440 you would use one leg of three phase 440/760 three phase power.
About 220 volts. They're just different voltage levels. 440 volt services can provide more power than 220 volt services typically.
