How To Convert Y Connection 3 Phase Motor Which Burnt Into A Delta Connection?

A three phase motor will usually have three contacts and a ground. Hopefully the ground is distinguished somehow. The ground will have no resistance to the motor frame.
Delta is dangerous, it has a 'hot' leg, 220 volts to ground. The other two have 110 volts to ground (or 115 or 120). You can hook up any of the three power wires to any of the three motor wires. If the motor spins the wrong way, reverse any two, it doesn't matter which ones.

Check for a motor start capacitor that is defective. This can happen without external symptoms. Highly unlikely Hotpoint washer has 3-phase motor. Most household loads are single-phase. In North American residences, three-phase power might feed a multiple-unit apartment block, but the household loads are connected only as single phase. In lower-density areas, only a single phase might be used for distribution. Some large European appliances may be powered by three-phase power, such as electric stoves and clothes dryers. Three wires could be for different speed ranges or one could be frame ground.

Some motors need a Y and Delta, with a special switch, to start up, you start with the Y. the motor starts turning, but does not give full power. after a few seconds (depends what the manual says) you switch to delta, to get full power. To let it run on full power in Y you need 1,4 times the voltage.
If everything runs fine, you won't have damaged anything.

It is simple to wire a Delta To Y or Y To Delta connection specially if your motor has a junction box. Also see for reference.

If you want it yo use in Delta, or in Y connection, both need al 3 windings. If one is defect, ir won't work in neither configuration.
Sometimes it cheaper to buy a new or even division motor, than send it in for revision yourself.

there is no motor that is single phase with 415 volts only 240 volt or 120volt and you cannot use a 3 phase motor on single phase it will just fail to start buzz and burn it up .single phase motors have capacitors 3 phase motors do not

A 3phase motor cannot be rewired to run on single phase power. You need a phase converter. A 3-phase motor will only run on 3-phase power, and a phase converter will convert single phase power to 3 phase. Just google phase converter. There are two basic types, electronic and rotary. The rotary type are more powerful and efficient, but lot's more expensive than the electronic ones. Your only other option is to replace the motor with a single phase motor. Good luck.

This site gives an excellent explanation of the star connection and the delta connection.
Answers.com - How do you wire a star delta motor

Then this site shows the wiring of the motor windings and the star delta starter and what occurs when the starter switches from star to delta.

Good luck.

what did you mean by single 3 phase? single phase motor have two wire output 110-110, 3 phase gen have 3 wires 110-110-110. if only two wires here ,this is single phase, all appliances are only single phase so you can connect it here, except some 3 phase motor or dynamo. the ac current has no polarity so you can connect to it all kinds of load depends upon the amperage of of your turbine generators

connection would be easier in the wye. single phase current is easier to pull of of one leg in the wye to get your common that you would not have in a delta connection. three phase doesnt require a nuetral. just 3 phase 120degrees out of phase from each other
