How do you rewire 460 volt three phase generator for 220 volt three phase?
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.

Outlet for standard electronics is 230 Volt , 50Hz The master feed into Swedish houses is 400 Volt three-phase , 50Hz. When 400 Volt three-phase is split in three single phases it becomes three single 230 Volt Bigger appliances , e.g Washing-machines, dryers, stoves, used to be 400 Volt three-phase, but nowadays most washing-machines and dryers are built for 230 Volt single-phase.
If you have a 208Y/120 volt 3 phase system, you can use any one of the three phases (hot or ungrounded conductor) with the neutral for 120 volt load or you can use any two phases of the three phase for a single phase 208 volt load. If you have a 120/240 volt 3 phase system, you can use any two phases of the three phase for a single phase 240 volt load or you…
400 volt three phase on a grounded system is 230 volt single phase, with each phase 120 degrees apart. So, if you have a 400 volt, three phase four wire service (grounded service), you can pull one phase off and reference to the neutral for 230 volt service. Note this may not allow 115 volt service, unless there is also a center tap for each phase.
