Generator from scooter motor

This project came about because someone cut the power line going to my house. The power company was slow to fix it, so I cobbled together a way to charge auto batteries for my invertor. The generator is the motor from a discarded electric scooter ( model MY1016 from JX Motor Co., rated 24v input and 2750 rpm). I removed the motor, it’s drive chain, and sprocket wheel and attached it to the frame of a discarded bike. The pictures show the details. By cranking furiously, I can charge a 12v battery with about 3/4 amp of current. There is a small epoxy rectifier to block the battery from driving the motor. This thing was made from parts on hand and cost me only the assembly time. I don’t have any sources or price lists.

Pre-purchase questions of a petrol-driven electrical generator - cos you guys know best! Thanks!

I have a caravan in a remote location and I've got round to thinking of buying a petrol-driven electrical generator. I'm figuring on using this with an ethanol (E85) fuel. I'd really appreciate some help if you can to any parts of my queries. I have looked around on Google for advice but there's a lot of conflicting stuff as usual and I know you guys are good. My normal max load is around 4,500watts but I have security HID lights which have a huge inductive start for a few millseconds - how will a suitably rated generator cope? Do I always add a 20% margin to the generator capacity so for a 4.5kW load I should get a 6kW machine? Or is it not 20%? Given that the machine will be outside, I don't want to annoy the other caravanners, so if I build a sound-proofing box with just an outlet for the exhaust, could I expect the noise to be reduced signifcantly, given a lot of noise will be coming from the exhaust itself? The machine has a tank of 15litres but I want to increase this safely - how could this be done, if at all? Safety is paramount (naturally) but then so is convenience. Do you have a generator? If so, what do you wish you knew beforehand or any regrets? What kind of maintenance schedule is there and is there a performace improvement for modding the air-intake to a larger filter like for cars and bikes? Many thanks for reading my question and thanks for your time to reply.

How would I build an electric generator with variable torque? It's my understanding that P=T*rpm, but that T is const.

I am interested in retrofitting a spiinner bike to produce electricity. The spinner currently uses brake pads to adjust the resistance. There is plenty of energy being 'lost' in the form of heat due to the brakes. I would like to be able to adjust the resistance of the bike without losing energy in the form of heat. I understand that gears are a possibility, but I would prefer to be able to adjust the resistance in a continuous manner. Any ideas? I've considered a CVT (continuous variable transmission) design, but this would be quite difficult. I've aslo wondered if the relative motion of a disk with permanent magnets to a disk of stationary coils would vary the resistance. I'm not sure what the range of variation would be however. Any suggestions or insights you might be able to offer would be much appreciated. Thank you.

Ok, I need a diode bridge to change 110 ac to 110dc.. So I plug it in and go..

Hi Everyone,  I really need some smart person with common sense to answer this... I just want a very simple easy way to plug into a wall socket and transform the 110AC to 110DC...I will be using this for a very large hydrogen generator... very low amp draw.... I know I need a diode bridge with maybe filters before and after the bridge...   So, now I need to put that together... I can not find a site that has one premade...   So, I would be very appreciative to anyone that can offer a web site for parts with part numbers and a diagram or instructions to put it together..   I am a Journeyman Carpenter for anyone that needs advice..  Thanks in advance.    I would be willing to purchase it from anyone that wants to make it for me..

Windmill Generator - why won't a small brush-less motor work as a windmill generator?

I bought a small brush-less motor that was designed as a motor for a small RC plane. I tested it by spinning it with a drill. I was surprised to find that the motor did not generate much in the way of voltage. Why not? It's too bad - many small brush-less motors are so nice. No brushes, ball bearings, and low cost. I would have thought that forcing a brush-less motor to spin would have generated power. Thanks for any insight.

I'm hoping some good mind out there would have some tips! Many thanks!

self excited self powered generator?

I have a portable generator (tiger diesel generator's alternator of 220v 750 watt rated power output) connected to a 1 hp ac induction motor using a pulley-belt system. The rpm of both the alternator of the portable generator and the ac induction motor is 2800 rpm so the size of the pulleys that i used are almost the same. Initially when i bought the generator i tested the output with a digital multi-meter and it checked right.(working powered by the diesel combustion engine). But i have coupled it with the ac induction motor i can only draw out 12 v ac at around 1 amp. I tested this from the same out put plug of the original generator. so I'm wandering what went wrong. Any one have an insight to this I would be grateful for your comments!
