How do you go from 208v to 230v?

You need a step up transformer unfortunately. Buy an Ugly's book electrical reference book. They're great and there is a transformer chart in there that will list the proper size or Kva that you will need according to your amperage need.


Can a 230-460 volt motor be connected to a 120-208 volt circuit?

Yes it will run. That said you will be shortening the life of the motor due to the excessive heat generated at the higher voltage. The insulation of the motor winding is related to the voltage that is applied to the motor. With excessive heat comes insulation breakdown. Once the insulation breaks down, the winding will start to short circuit. With a short circuit on the motor winding copper wire is lost. Think of a welder when an arc is struck. Once this happens to a motor it becomes non operational and a rewind is the only way that the motor is going to become operational again.Install a Buck & Boost transformer rate for the HP of the motor that will Buck the supply voltage for the motor down to 230 volts. This is the recommended way and the only way it should be done. Any good commercial electrical supply house can help you properly size the transformer that you will need.Read more: How_do_you_run_a_motor_208_volts_ac_in_a_230_volts_suply


I need a 120V 208V 3 phase What size of 3 phase transformer do you need?

The sizing of transformers is based on an accumulation of all of the loads that will be connected to it. Add up all of your loads and possible loads in the future and then tell your installer the figures and they will use these to calculate the size of the transformer that is needed.

What capacitor should you use on my step up transformer with an output of 220v so you can use it to run my 220v 60hz motor?

If you have a transformer with an output adequate to run the motor, use it directly for the supply to the motor control circuitry. Remember when dealing with motors, the start current will be about 300% of the full load running amperage. Size the transformer accordingly.

Can you change 24 volt to 110 volt?

No, a new circuit from the electrical panel would have to be installed using a 2 pole breaker of the correct size along with the corresponding wire size to accommodate the amperage of the motor.

How would be the best way to plug a small motor 12 volts to a wall?

Most 12 volt motors run on DC, so you would not only need a transformer to change from the utility voltage, you would also need to convert to DC. To change to 12V DC you will need a transformer and some kind of rectifier. You can usually purchase a converter for that purpose, but it must have sufficient capacity to produce the current required by your motor. The brand of transformer is insignificant. Typically, most cities of significant size have at least one surplus electronics retailer. These are places that buy left over components from manufacturers or other sources and sell the components at a significant reduction. To power your motor, determine the current draw of the motor,then calculate the V/A rating and add between 30% and 100% to provide a little safety factor. You'll need both a transformer and a rectifier capable of that capacity.

What is the relationship between frequency and the size of a transformer?

Basically the characteristics of a transformer depends on the impedance(resistance) and on the coupling of its primary and secondary coils. The impedance of a coil depends on the frequency, as the frequency increases you need less volume of iron core and less number of turns in the coil for a given impedance, then reducing the size of the transformer.
