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.

First look on the generators name plate to see if the generator has the capabilities to output 220 volts. If it does then open the junction box that sits on the top to the generator housing (not to be confused with the generator's breaker box). Inside you will see multiple taps that can be repositioned to give you different output voltages. On the underside of the junction box lid there should be diagrams as to how the taps should be rearranged to get the specific voltage that you are looking for.
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.

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.
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.
Yes.
The standard units were 220 volt, 3 phase. 220 single phase was a purchase option. There were also conversion kits to convert the machines from 3 phase to single phase. The kits contained a 1 HP 220 volt capacitor start motor and a DC motor brake control assembly. Jerry S greentron@att.net
About 220 volts. They're just different voltage levels. 440 volt services can provide more power than 220 volt services typically.
Buy either a phase convertor or motor-generator with the proper input and output ratings. Essentially you have to generate your own 3-phase power using the 220V as the energy input. There is no wiring or connection scheme that will directly do this.
