In order to charge a battery with a motor it is necessary to use mechanical energy to spin the motor and the energy then comes from the source of how you are spinning the motor and goes to the battery where it is converted to chemical potential energy and heat. with better bearings and better commutation. An AC motor powered by a power inverter usually runs hotter than an AC motor fed with pure AC power. Didn't you know you can find all the answers on the internet...they might not be right, but because they are there they must be. © 2009-2020 Premier Farnell Ltd. All Rights Reserved. All you have to do is connect the amount of DC voltage to the motor which it is rated for. 2AM here and time for me to shut down for the night. As for (complex circuitry), what would I need? It isn't. The current is also limited if you use L293D. Although arguably you couldn't say you were charging the battery because the net flow of current would be out of the battery not into it. The inverter has to be able to handle those current requirements as well. I am quite sure that you have NOT seen any such thing but it may be that some freak circumstances or clever tricks have deceived you. You just can't do it at the same time you're powering the motor. When I was younger and did not have the training I have now. T2 and t5 act as common connectors. Look up regenerative brake "https://en.wikipedia.org/wiki/Regenerative_brake". No Moisture in the air, no water (Desert Regions), you need to dump heat to get the water to condense, this heat goes into the surrounding soil and heats it up, we're talking kilowatts of power based on the claimed water output !!!! DC motors normally have just two leads, one positive and one negative. i need to charge my trolling motor battery. I was just thinking outside the box. This is the real mystery ... how is it possible that someone tried to propose energy solutions. ... InverterAn inverter takes 12 volt DC battery power and converts this electricity into 120 volt ac power. Regarding your point, yes if there are inefficiencies resulting in heat then that could be collected to allow the battery to run longer. shabaz is correct. How about we have two batteries? It would probably output that amount of water where I live, if you add the rainfall. When the DC motor is creating high RPM's, this energy would be used to recharge the primary battery, while also powering other components within the device. Please type your message and try again. This does NOT mean "you should know before asking" but "be curious and search to see what is the point". Okay, so the overall ruling is that this is entirely impossible then. I'm working on a similar project. I agree with. The crank is keeping the motor spinning and the electricity that is being made by the motor by our efforts on the crank exactly equals the energy supplied from the battery. But since then, and with the advancements in the field of electronics its getting closer to that dream of coming true. until then do not doubt the imposible cuz it is already there in nature, Wow, it is very simple and a few good engineers have already tried to explain, There is no free lunch, there is no system that is 100% efficient, never mind over 100%, there are some very lab science research specific examples that are close to 100% but still less than 100%. I am interested in spinning a PMG and kick the wind out of equation. so without finding a way to reclaim the heat loss or get rid of the friction, no there is no way at present recharge the battery with the motor as it is. Might work well in places like California where there's plenty of sun and it's never covered by snow. However, many appliances and electronics use direct current (DC), which provides consistent power to the device. Not the first time someone has taken something that's theoretically possible and then added a "marketing spin" to make a buck. But that doesn't mean I am hanging up the idea. but it is impossible. Most cars and motor homes derive their power from a 12-volt battery. This battery will power a brush-less DC motor. A 12 volt motor makes 120 . Of course you can charge a battery from a dc motor, that's how generators work. Here is the example: You have let's say a 16,000mAh 6S Lipo Battery. But since then, and with the advancements in the field of electronics its getting closer to that dream of coming true. but for DC purposes are not feasible. If you connect these two leads directly to a battery, the motor will rotate. This battery will power a brush-less DC motor. This is the second principle of the thermodynamics. Error: You don't have JavaScript enabled. Connect t3 and t4 to the negative terminal of the battery or power supply. I think the fundamental understanding about energy is that it is always converted into something ...it's never lost just converted. This is a simple DC motor connected to a D-cell battery. Just as I posted my last comment, it seems that I had some others come in. Over the top irony should be always welcome, in my opinion. There are no advancements in the field of electronics that could achieve this. But the "free" energy is obtained from the heat in the outside air. This was an Ideal I had but getting and understanding the same explanation you gave I let it go until I seen on inscrutables an article on how they are converting heat back into electrical energy. But the power from regenerative braking comes from slowing down the vehicle. I am building a quadrocopter with four 6V DC motors and an arduino nano. On a serious note... like others have already said, the energy that turns the charging motor must come from somewhere, heres another example; Your car battery keeps its charge because of the alternator motor that spins from the cars engine. The battery should also be able to supply the motor's needed current. In this case energy from the higher voltage battery spins the motor as before. i just burst out laughing for no apparent reason as far as the people round me are concerned hah! yes you're providing less PAID for energy that you get out, but that other energy is coming from the surrounding ground, Ah ok I understand, I didn't even think of those details. I understand that we will not be able to totally recover all of the heat, but if enough was recovered and turned back into electrical energy. shabaz did a good job of summarizing and expanding my post. Its easy to believe that this energy is free because the engine is already running but in reality causes a small amount of drag, and wastes some energy through heat, light and sound. anyway, its a complete scam, the physics does not add up, same for solar roadways, same for using the motor to charge the battery is is running from. I agree with mcb1. Example two: We have a battery spinning a motor and at the same time we have a battery of a lower voltage connected across the circuit. For large scale generators I think they may already perform heat recovery. If you can get the battery to run the motor, write it up in a science journal. We will always have less after the process than we began with. The solar panels charge the battery when the motor is not running. Since electrical energy can only move one direction at a time we can not use the battery to spin the motor and use the spin of the motor to recharge the battery simultaneously at the same time. Isn't there room for thought on that approach? So how do you get around this. Originally Answered: How can you power a three-phased motor from batteries? Or do I have to pull away from even designing a cooling fan for my motor? How an electric motor is connected to a DC battery depends on what type of motor is being used.
