audiofanaticz Posted October 23, 2012 Report Share Posted October 23, 2012 a 7hp motor is going to be rather large size wise. hell the 5hp 220volt motor on my cabinet saw in my garage is huge. I couldnt image trying to tote around a 7hp all over. LOL Hell of an idea tho!!! Im sure with a correct pully size you could get that alternator spinning pretty fast, but once a load is on the alt the rpms will drop drastically . But like Tony is saying, I kind of have to agree with that. I know under full load my high output alternators claim to use up 16-18hp each. How the horse power from a vehicle differs to an electric motor I dont know, but Id assume Horsepower is horsepower no matter what type of motor, Quote Link to comment Share on other sites More sharing options...
meade916 Posted October 23, 2012 Report Share Posted October 23, 2012 i think its being used as a charger, not a power supply. It would probably work ok, however pretty wasteful, for a battery charger Quote All SMD products + MORE available at my store here! https://wccaraudio.com/ Subscribe to My Youtube Channel!

HatersGonnaHate Posted October 23, 2012 Report Share Posted October 23, 2012 This concept would be more useful along the lines of the people who thinks it's 100% legit to plug the batteries into a charger and demo all day with the car off.....

Mike Whitenton Posted October 23, 2012 Report Share Posted October 23, 2012 Guess I'd better take down the lightning rod quick charger. Dang. Limiting current is stupid. One minor problem here. Lets assume a 300 Amp alt at 14V = 4200 watts output. Assume 80% efficiency to convert the energy: so input to the electric motor = 5250 watts. So at 110V that would be 48 amps (not gonna happen). You would need a 30 Amp 220V setup with a 7 horsepower motor. Cool idea though Quote Link to comment Share on other sites More sharing options...
LBM Posted October 24, 2012 Report Share Posted October 24, 2012 You would need a 30 Amp 220V setup with a 7 horsepower motor. Cool idea though Even a 5 HP motor will also work !!! As this will be used when giving demo the current demand would not be continuous and these ac motor can take some overloading !!! The one used in the photo is a similar one approx 3-5 HP , but the alternator is also a small one maybe 220 amps. Quote http://lbm.net.in Link to comment Share on other sites More sharing options...
Mtnbikecrazy55 Posted October 24, 2012 Report Share Posted October 24, 2012 i still think its a cool idea, regardless of how efficient or not it is Quote I hate long signatures.... ...what the fuck is wrong wiht you you fucking fuckity fuck fuck head...

Hondabiker95 Posted October 27, 2012 Report Share Posted October 27, 2012 The coolest part about this to me is the demonstration of energy transfer. It starts as 120V AC from the wall, goes into the electric motor, converts to mechanical energy, then the alt turns it back into electrical energy, but this time it comes out as 12v DC.

How the horse power from a vehicle differs to an electric motor I dont know, but Id assume Horsepower is horsepower no matter what type of motor, I agree with tony any you.... but my comment goes to show the difference between electric power and gas (motor) etc power... So most people have rode a dirtbike.... ever rode a electric dirtbike tho? They are wild.... insane amout of torque # for # vs a gas bike its much much quicker, but they top out very fast.... Electric motors have really advanced over the last few years same with the batteries My bike has 18nm of (force) seems like a shitload cuz its all upfront unlike with gas The new ones have 64 nm and 54 horsepower..... nuts if you ask me Look up zero bikes Thoes bikes sure make it seem like that thing would work Quote SCSB Santa Cruz Speaker Box Build logs: Daily Driver Lemon Marquis 2 american bass 750.1s 350.4 on 14 focal 6.5s sq 945 on 4 hertz tweeters Mystery subs http://www.stevemead...__fromsearch__1 The Mustang 'dubbed' Shirley the project from bullet holes to badass http://www.stevemead...cond-skin-time/ Link to comment Share on other sites More sharing options...
