The frequency of the generated voltage depends on the speed of your engine. I assume it's a gasoline engine. It's probably spinning at about 3600 rpm. You need to get a mechanic to fiddle with the govenor and drop it down to 3000 rpm. 50HZ is 83 percent of 60Hz so you need 83 percent of whatever speed you are currently running. My question is, why bother?
A very important note
There is no such thing as a 120 volt 50 Hzservice! (But see >> Correction! << below.)
Various countries around the world use 230 - 240 volts at 50 Hz as their standard national single-phase service - not 120 volts - so the two further answers which were given earlier - shown below - only apply to those standard 50 Hz services, none of which can deliver power to 120 volt appliances unless a transformer is used to drop the voltage.
However nowadays many small personal electrical items - like electric razors, camera and music player battery chargers, etc. - are already designed to operate either on 230 volts or 120 volts so it is worth checking the products' rating plates or user manuals.
If such an item is not already a "dual-voltage" type then low-power small "international voltage-converter Transformers" may be available to buy from some airport shops or from specialist electrical stores, but usually the best thing to do is to buy a dual-voltage model.
For large domestic appliances, such as washers and dryers (as are mentioned below) it is usually impractical to use a step-down transformer for reasons of their very high cost and very heavy weight. It usually makes sense to buy either new or good second-hand models in the 50 Hz country.
Further answer 1
As far as I know the only results are 1) Increased current draw and 2) Motors will run slower (such as washer agitator, dryer drum, and clocks).
Further answer 2
50 Hz power will cause synchronous ac motors to run slower than they would on 60 Hz. Synchronous AC motors rotate at exactly the supply frequency. Mechanical clocks made for 60 Hz will run slow on 50 Hz, loosing 10 minutes every hour (or 4 hours every day).
Appliances that rely on inductive AC motors, like washers and dryers and fans will usually work ok.
">>> Correction! <<Some countries DO use 120VAC 50Hz service!Most countries use 220, 230, or 240 volts, usually at 50 Hz,
many also use 110, 115 or 120 at 60 Hz, but there are exceptions:
Barbados uses 115 V at 50 Hz.
Liberia uses 120 V at 50 Hz.
Jamaica and The Marquesas Islands in Tahiti use 110V at 50 Hz.
Libya, Monaco, Morocco and Madagascar all use 127V at 50 Hz.
Japan uses 100 V service, at 50 cycles in Tokyo, Kawasaki, Sapporo, Yokohama, and Sendai, and 60 cycles in the West, in Okinawa, Osaka, Kyoto, Kobe, Nagoya, and Hiroshima.
Peru is 220 V at 60 cycles.
There surely must be other exceptions.

Most AC voltage supplies that need changed to another voltage, either up or down are changed with a transformer. To change 220 to 110 use a transformer made for that purpose Make sure that the wattage rating is the proper size for the load(1500 watts etc.) properly fuse and ground the transformer Warning - voltages in this range are extremely dangerous make sure you know what you are doing
Yes, BUT rotating machinery should not be as the appliance might over speed and wit little back EMF might burst into flames!!

If the load is totally resistive there should be no problem with this connection. If there is a motor load associated with this appliance then this connection is not recommended. Frequency governs the speed in revolutions of the motor. In some appliances this will have a detrimental effect in its operation.
a transformer is your best option.
Not unless the appliance is rated to be used with the two different power supplies. The US uses 120v, 60 Hz if it plugs into a receptacle, and possibly 240v, 60Hz if it is hard wired. The UK uses 240v, 50Hz whether it plugs in or is hard wired. These two power systems are NOT compatible. You may use a US appliance in the UK, and vice versa, only if the appliance is dual rated, i.e. the appliance says 120v/60Hz AND 240v/50Hz on the nameplate. If the appliance only specifies one power supply, it can only be used on that power supply. If this is the case, you may be able to use a travel adapter to operate the appliance.
120v, 240v and 347v for lighting
The UK uses 240V, so your dryer will probably work, as the US uses 240v in homes for dryers. However, your washer won't as the US uses 120V for washers.
It is important that you should read see the answer to the Related Question shown below: "Can you plug a US 240v 60Hz appliance into a European 230v 50Hz outlet?".No, sorry. Most US dryers have a 240V heater and a 120V timer and motor. While the heater will work fine, you don't have the 120V supply for the timer and motor. Also the timer will run slow on 50hz if it is not solid state (Most dryers still use motorized timers), as well as the drum turning slow, and the airflow being decreased.If you have a sufficiently large voltage converter you can make a neutral for it, but you have no way to know how much current the neutral pulls without testing or cracking it open.You may want to just sell it and buy an Indian dryer.
Your compressor is a dual voltage compressor. The original installer followed the instructions to switch it (probably internally) to the 230 volt setting or to internally wire it for that voltage. The label or information plate on the unit may only indicate the higher voltage rating. You don't have to do anything.
In the US, both 120v and 240v will be needed for your home, as different appliances need different voltages. Your TV needs 120V, while your electric dryer and stove will need a 120V/240V supply. If you have an electric water heater, or central AC unit, they will need a 240V supply.
You can use 120v 10a 125w cable projectors 110-240v power in India.
the simplest solution is by connecting two 120v 3amps heater in series , the same can be used directly on 240v. However the current drawn will still be 3 amps & Not 1.5 amps. The heater output power will be double that of a single heater running on 120v. ( or equvalent to two heaters operating on 120v. supply ) A more expensive method is to use a stepdown transformer which can be powered on 240v & connect the heater on the transformer 120v side. this method will consume approx. 1.5 amps from the 240v supply.
Power adaptors are readily available that plug into Australia's 240v outlets, converting to 120v. Find them in travel, luggage and electronics stores.
No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V
Theoretically that can be done with transformers, but the power available would still be limited by the circuit breaker on the original 120 v supply.
No.
Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180° out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires.
Not unless the appliance is rated to be used with the two different power supplies. The US uses 120v, 60 Hz if it plugs into a receptacle, and possibly 240v, 60Hz if it is hard wired. The UK uses 240v, 50Hz whether it plugs in or is hard wired. These two power systems are NOT compatible. You may use a US appliance in the UK, and vice versa, only if the appliance is dual rated, i.e. the appliance says 120v/60Hz AND 240v/50Hz on the nameplate. If the appliance only specifies one power supply, it can only be used on that power supply. If this is the case, you may be able to use a travel adapter to operate the appliance.
Power = Volts x Amps. Hence 1kW is irrelevant of voltage.
More than likely, your 240V system has branches that supply a standard household 120V to things like lighting outlets. Most light bulbs in the US run on 120V so this is probably a convenience feature. Otherwise you would have to go to a specialty store and buy 240V bulbs.
Off hand no but your explanations are not clear as to who is doing what to whom,,
