Making an Electric Generator Mobile Functionality Check
Author: Noel Siegel
These days, electrical appliances and electronic gadgets have become more compact and more functional. Yet despite the apparent decrease in size of most of these consumer products, mobility is the foremost reason why appliances have gone handy. Even now with an electric generator mobile functionality being integrated. But how functional really is a portable generator?
Size isn't always the most fitting criteria to use when buying a mobile electric generator. In fact, most home users end up getting power shortage from their small and handy generator. When choosing a mobile electric generator, check for its constant wattage capability. Constant wattage refers to the total wattage of all the appliances your electric generator is expected to provide power for.
You can compute the constant wattage by adding the wattage or power consumption of the appliances you are going to use. A regular room air conditioner typically has 1700 wattage, a freezer has 500, microwave oven has 700, radio has up to 200, and a portable heater has around 1300, while TV has wattage up to 500. If you add all these up, this will total to 4900. An ideal mobile generator should provide power that is 20 percent more than the constant wattage, which in this case, is 5880. You can refer to the appliance manual or the back label to get the wattage of a device.
If you are going to use motor-powered appliances with your electric generators, be careful also with the start up wattage. Start up wattage is the power needed to start motor-driven appliances, such as furnace blowers, freezers, and refrigerators, which normally reach up to three times its average wattage. A refrigerator, for example has 3000 wattage, but it will eat up 9000 of power in order to start. So, if you're going to use these appliances, the best advice is to check for a mobile generator that surpasses your constant wattage requirements.
Another important thing to check is the voltage ratings compatibility. An electric appliance can either have 120 or 240 voltage ratings. Huge appliances, such as dryers, electrical ranges, and pumps for wells have 240 voltage ratings. If you plan to use both 120 and 240-volt appliances, go for a mobile electric generator that can serve these two voltage ratings.
In order to get more optimized performance, check out accessories that come with the mobile electricity generator, such as a transfer switches. A transfer switch will allow the generator to provide power to a selected circuit in a house or facility. Other accessories, which will add more functionality to your generator, are generator power inlet boxes, generator power cords, generator wheel kits, gas and oil cans, plugs, and connectors.
Mobile electric generators are not expected to supply power to an entire home or work site. However, you can make the most out of it by checking the necessary compatibility features. Make this as your mobile electric generator functionality checklist.

Is there possible that I can make generator without any fuel?
Like a project that I’m doing right now, I’m making generator without a fuel or deisel engine.
Make generator that can generate enough power to boil 1 cup of water of electrical hot plate?
Your Device with two output wires then to a 200W 9V DC to 110V AC Converter then 110V hot plate with a pan of water.
No more then 10V
Boil in Less 10 minutes
Common household materials with value than $2
Raw materials
must signigicantly improved of modified from what you tell me.
when making a generator do you use insulated or uninsulated wires?
Making generator out of motor?
I know this is possible, and I was reading an article that says I should add capacitors in parallel with the motor power leads. These should be running capacitors, of about 150-200 uf. I was wondering what exactly the “motor power leads” were, that is a rather vague term? Also, if you know why the capacitors are necessary, I’d appreciate that answer too.

im making a generator and the wire broke how to connect them back together?
im doing a science project and i have to build a generator. will i was building it part of the coil broke. how to i reconnect them. can i twist them together please help me.
The winding wire will have enamel on it.That is a bad conductor.U have to remove enamel with a knife or blade or sand paper, then twist them or solder them to get good connectivity.
There is a lot of possibilities starting from the simplest one which is wind generator. More complicated would be water generation where a usually dam is build and potential energy of the water accumulated behind the dam moves water through turbines and generates power. Some other may include thermal energy of the earth. If you drill deep enough you will get to the earth crust zone where temperature is high to produce steam and this steam is converted (generated) into the electric power. Ocean waves are also source to generate energy.
Running a motor “backwards” leaves an opening for misunderstanding. The motor has to have another motor to make it spin, as a generator, or alternator is spun by a motor of some kind, such as the alternator in your car. To answer your question, a DC motor, with permanent magnets built in to it can be spun by another motor to make the DC motor act as a generator. AC induction motors are a lot different. Taking power from a running motor, there is no method that I am aware of because there is no way to draw electrical energy from the motor that is using the electrical supply to make it run in the first place. That said, using another motor to spin an AC induction motor, and injecting an AC voltage into a winding of it, that is independent of the winding that you want to draw power from, that is possible, and is done by a lot of people. The best motor to use is a 3 phase motor. Ground will be common, which is the motor frame, usually, one winding has an exciter voltage applied to it, and another winding is the one that power is drawn from. Yes, this can, and does work. Will it be efficient, maybe not as good as a wound rotor motor, or an alternator made for this function, but in a pinch, use what is available.
they are always insulated, but for the non-trained eyes they can seem to be uninsulated. The wires for generators, motors, transformers and so on are coated with a very thin insulating layer which is transparent, thus is hard to note if you do not know that it is there.
This layer is called “enamel” and it is of a polyurethane, polyamide, or polyester resin.
You need a low-voltage lighting transformer (rated 200W or more) and a means to chop the voltage at the primary. The transformer will be by far the biggest expense.
A common way to do the chopping is to use a Royer oscillator. Vibrating coils are were common in early automotive radios; they’re still used in cheap inverters.
Link below has some circuits.
A more efficient way would be to step up the 12V to 120V DC, using a flyback topology. You still needs some coils but you could run at much higher frequencies and avoid the bulky transformer.
