Air compressor 220v to 110v
Nice picture but not good enough to read the nameplate info from where I'm at. What does the name plate say for volts? and for phase, two lines or three lines?
Beware of this, the air tool you will be using requires a certain amount of volume of air, measured as CFM (cubic feet of air) and a two horse compressor may produce you about 5 cfm when new and in good condition while the tool may require 7 - 15 cfm. This scenario just won't work well. The tool should be supplied with a decent volume of cfm to work right.
The next thing is 220/240 volts vs. 110/120. The amount of juice, called amps is twice in a low voltage hook up. Example is your 220 volts motor needs 10 amps and your 110 volts motor needs 20 amps feed. If you multiply the set of volts and amps, it will equal the same as the other set. These are called volt-amps and are synonymous to watts, watts is power, you pay for power measured thru time, the watt-hour is what you consume.
With the above given, referring to amperes, or juice, this determines the thickness of the wires feeding the motor. A little juice needs only a thin wire (such as with high voltage hook up, 220 volts) and more juice as with a 110 volt hook up, will require a thicker wire.
Not meeting into consideration the wire thickness and using thinner wire than required presents a major problem with friction or resistance to juice flow, power loss in the form of heat. Power loss includes voltage drop, loosing volts in the skinny wires. This scenario leads to burnt motors, tripping breakers and blowing fuses, you can oversize the wire thickness but not underside it.
The use of a high voltage is an advantage in saving copper and money in considerably long runs of circuit conductors. Power companies distribute power at 10 times higher and more than what consumers use to save in copper and power loss, good for transmitting power far. Then by use of a transformer, mounted on poles, they reduce the power to consumer level. 240 volts with a center tap. This is how and why we get 110/220 Volts three wire.
I hope you find an answer in all this mumbo-jumbo of electricity. See if the motor is dual or single voltage, the name plate will say this info. If dual voltage, then the motor connection will have to be reconfigured for whichever voltage it is changed to.
