What kind of Electrical motors can generate electricity?

Question

I made a permanent magnet motor, that turns fast enough to maybe create charge. I need to know what sorts of electrical motors will make a dc current. Can I use any battery operated motor, like out of a handheld fan or a remote control car?
Is there a "best" way to make electricity with a rotating shaft?

Answer 1

Wild Bill is wrong... but I'll just bet he's becoming used to hearing that. Yes, any DC motor will produce a DC current if the shaft is spun by another force. The best example is one of those little DC cooling fans for your computer. Computers have to use DC current, so the power supply converts the AC to DC. You can buy one of these fans and put it into a stiff wind with a voltmeter attatched and you'll see that it can be done. AC motors will create a current, but won't charge a battery without some modifications.

Answer 2

A permanent magnet, DC motor with brushes will generate an electrical current when the shaft is spun. Lots of older farm equipment used the starter motor as the generator because of this fact.

Answer 3

initiate before everything. There are 2 very distinctive style of "hybrid" vehicles. A parallel hybrid like the Prius will use an electric powered motor alongside with a gasoline engine to power the wheels. The gasoline engine will additionally power a generator that's used to value the battery a chain hybrid makes use of a gasoline engine to power a generator that makes electrical energy to the two value batteries or function an electric powered motor. The Volt is equivalent to this layout even nevertheless the gasoline engine/generator would be unable to recharge the batteries and the motor vehicle specially situations makes use of the two the engine and the electrical powered motor blended for power. even nevertheless GM marketed the Volt as a technological step forward this layout replace into used for extra suitable than seventy 5 years with the aid of the GM electromotive branch in making diesel/electric powered locomotive prepare engines. (1930 to 2005) an electric powered motor would be as much as approximately ninety 8% efficient at changing electrical energy to mechanical action. those in maximum commercial electric powered vehicles are eighty 5% to ninety 5% efficient. we can anticipate a generator to have the same intense performance. with the aid of assessment the theoretical performance of an inner combustion engine working on popular gasoline is 27% at the same time as easily performance on the wheels would be under 15%. cutting-edge electric powered vehicles would be approximately one hundred# or a pair of million/4 the burden of a piston engine. The Prius gets remarkable gasoline mileage through fact a smaller petrol engine may be used and the electrical powered motor is used, the motor vehicle will stop the petrol engine in site visitors and the motor vehicle has regenerative braking. The Volt isn't as efficient yet makes use of the extra efficient electric powered motor to exploit power stored in a bigger battery which would be charged no longer with the aid of a petroleum engine yet with the aid of extra efficient power plant life and the electrical powered grid.

Answer 4

Old fashioned car generators (before alternators) were simply direct current motors that were turned by the fan belt, producing electricity. They used carbon brushes on the rotating stator to create the electicity and pass it to the distributor and battery. As a p.s., alternators produce a.c., however it is rectified to d.c. by the inclusion of built-in diodes. So a modern alternator puts out d.c.

Answer 5

There are two options:
1 - Move a magnet across a metal wire
2 - Move a metal wire across a magnet

The motion needs to be continual in order to induce an electrical current. The faster the movement, the more electrical current.

Answer 6

Electric motors run on electricity, and can not generate it. You need a generator to do that.

Answer 7

Something using methane. Possibly even magnets.
