This project is fascinating. Check out episode 7 of Fastest Car. They have a ‘72 Datsun 1200 that held the title of fastest electric car. It uses a generator out of a DC-3 aircraft for the motor. It takes up about the same space under hood as this motor, but produces so much power, that it does the 1/4 mile in 10.25 at 126mph. The battery packs are not car batteries. They are a futuristic looking panel that fits in the tiny trunk. I would contact those guys if you feel like taking this project somewhere. Also they use a volume controller for their throttle too. Lol

What a nice toy, I would love to see it in action 👍
Hi I sold it to someone who plans to gut it out put everything into Alfa spider. The fiat body was super rusty...I made a webpage of its history:
alternativeworldenergy.wordpress.com/chapter-7-electric-car-conversion-of-69-fiat124-spider-using-36v-400a-dc-forklift-motor/
volume control gas pedal.... brilliant.
I love this video and others similar. I believe the innovation for the application of electric cars and alt energy required to make it affordable for everyone will come from diy'er garages. In many cases now these are rich people novelties. The future looks brighter. Thank you.
I don't like the motor that much - got it for 75 bucks....only goes to 36V and when it really chugs up hills and drops rpms down very low it gets hot...if living in very flat area this conversion would not be too bad...I make free-energy motors and generators, plan on putting these in electric cars and boats sometime MrDKonzen is my youtube channel if you want to see the motors
This is amazing. Would you mind expounding on what motor you chose and why?
Love this.. Thank you for posting this!!!! So did it ever do better? what do you think it needed? know HP and RPM rating on motor? know your cars dry weight? RWD? know your differential ratio? Do you think you could have connected directly to your drive shaft or differential? At low speed do you have more torque? Somebody told me I had to I might be able to do with 2500 blazer and direct drive if I can reduce differential ratio to about 8:1 (from about 4:1) .. It sounded like your transmission was just getting in your way... Thoughts?
You have to torque those down really good torque them until they're real tight and they start to loosen off a little bit
It's rated at 36v and 400A so around 12 KW you could say at full power "possible"
Awesome ingenuity
Hi Jay
Thanks, I sold the car last summer to someone who wants to drive short distance to work with it.
The batteries were shot needed new ones (250 each ) door had rusted off and I had lost garage and big old farm space you see in video.
I wanted to put some free energy generators on the motor shaft, I had left space for this but never got to it. Look around my site for free energy motorgenetator stuff I do plus fuckedtones music some not so bad ..
Thanks for writng!
As long as the speed pedal doesn't end up underneath the brake pedal all will be fine.
Hi goracks69
Yes I have seen videos of that white electric datsun1200 and looked at their website. I saw then they had two very powerful DC car motors and had them in parallel from stop them switched to series after a few seconds (maybe series then paralell??l
anyways their motors same basic design as this forklift motor with 4 big brushes very simple design
When I had no speed controller i had built simple copper contact switch either on or off the car would lurch forward great force from all the amps and I would brag it could beat any car in race from 0 to 20 feer...i need to take out that clutch I put in it made it worse. Car h always had problems going up steep hills as motor bogs and runs slow battery terminals get hot ruined one battery as terminal melted
need to lighten car more take off doors next step I am in eastern europe now cannot work on it until spring if lucky
Also want convert batteries to Alum batteries no lead acid look up John bedini on this subject also I have some special motors built to replace the forklift motor look at my site mrdkonzen for.the designs want to charge batteries as motor runs via Muller motor generator in there
just a question why would you even need a clutch
Idea was to make it so I could rev motor up in revs, and downshift like from 3rd gear to 2nd gear while beginning to go up steep hill for instance also idea was to get some good flywheel effect too to help power instead, however top speed has been cut down from 55mph to 35mph with fully charged batteries so I plan on removing the whole clutch flywheel experiment, and inserting a Muller type flat rotor motor.genrator in that space hopefully will finish this before summer 2015
Probably one of the most "crappy" assemblies I've seen. LOL
BUT on the other hand, fascinating. ;-)
For some reason your video got me hooked, I guess the combination of ingenuity, low budget and "make it work" spirit, combined in that Fiat 124 Spider body. It's indeed quite nice.
If budget/time allow it, an upgrade in voltage and controller, let's say 72V will make for a very decent ride and reduce the amps put trough those connections (less heat).
Reducing/simplifying the mechanical side, gearbox/clutch, will also help. :-)
Thanks for sharing, thumbs up. :-)
Thanks it really is a piece of junk I agree the fiat should of been junked long ago, the motor was 100 bucks the controller 75 bucks batteries expensive at 200 bucks apiece however....goling up hills, if not terminals super tight they get red hot, I ruined one of the batteries as the terminal dislodged internally from the heat...this car only good on very flat roads as is..the clutch addition made it worse need to go back to direct motor to tranny....there is room to put extra "free-energy" type of motor/generator in between tranny and motor which was next step as I build stuff like that ...this I wanted to do to recharge batteries as it drives, give it some more power up hills but now I am in Minsk Belarus will return when wife gets USA visa which might take awhile....thanks again
Doug Konzen - No way, keep that Fiat Spider. Might be a junk but definitely a nice piece of junk. Make a wonderful base for a restoration. project. :-)
Guess your to close to a stall condition and Amps sky rise accordingly.
Possible to play with the transmission or if available a set of lower tires on the drive wheels.
You mention on another comment 50mph that seems way high for such a small motor. Closer ratio on the final drive might be part of the ticket to make it work. :-)
Thanks for your comments.
great video work
If u told me this thing was electric I would laugh at u lol 😂
Good work Mr. where can I get all the parts in a good price.
the motor, the speed controller and the pedal for to speed the motor.
Hi JoseThe motor (36VDC 400A forklift or "fingerlift" motor) I found in scrapyard but you can find them on ebay. There are lots of PWM speed controllers on ebay too - they are used for golf carts.The pedal is a guitar foot volume pedal, and I put inro it a potentiometer of the type that will control the speed controller....
Does your motor controller need to be programmed via PC Software?
Hi Mings
No software programming needed. It is just a speed controller for a golf cart motor, rated at 36V and 400A.
4 batteries at 48v and golf cart speed controller rated at 48v would be better for going up hills
Doug vry very cool!!!
What's the kw rating of the motor?
400amps and 36v motor so about 12KW
Great job doug
Which motor and cantroller use this car ???
What no Flux Capacitor
You really took that down the road 🤔
Why does this remind me of a game "my summer car"?
Satana...
Best build ever... wahwah for gas 😅😅
how much power is it making
Top speed on flat road is 50mph at 36V worth of batteries - does not like to go up steep hills however and so have to crawl up steep hills in 1st or 2nd gear - It lost lots of power when I put in the clutch and flywheel as now top speed is way down to about 35mph which is big drop, so am going to take all that out and go back to forklift motor directly on 4speed transmission and when you want to shift, cut power to motor.... olans also are to put 2nd flat-rotor "axial" type motor-generator between motor and transmission to give it a boost. WhyDidYouTurn
MrDKONZEN very well then
the power steering? do you remove it?
there is no power steering in a fiat 124 spider! I removed everything else though....
MrDKONZEN is it not hard to steer?
no it is easy to steer...those three batteries and forklift motor weigh a bit less than original gas motor and radiator and accesories
top speed with fully charged vs discharged battery?
50mph flat road fully charged, half discharged around 35 or 40....does not go up hills well when motor has to go too slow it gets hot especially battery terminals....flat roads OK though
did you sit at a particular gear? when you control speed is torque greater? weight of car?
Range?
What is the range
Hi Do Chinigan
With the three 12v golf cart batteries in series for 36v it only lasts one hour at best on flat road going low speed drawing say 90amps and going 25 or 35mph but going up steep hills the motor draws near 400A as motor goes into low rpms in first gear too and now batteries get sucked down very fast.
@@MrDKONZEN thank you sir
@@MrDKONZEN sir what if you took and ran a series of alternators and Daisy chain them say one on each able and one directly off the drive and use diesel truck batteries as the higher amp battery may last longer ... Let's say you did use 3 diesel batteries and had 3 18 wheeler alternators would the motor still drain the batteries faster than they could chargw and if so then I what if you hook up a totally separate charge system like say on the rear axle away from everything as I don't know if it would cause an EMF disruption or not but anyways move two alternators to the rear axle and have them both going to a very high powered inverter to run a very strong battery charger so that it will feeding as the Moto was turning like a self contained system ...you could put it in place of the fuel cell
will it caused a fire if you put more voltage on a 36 volt motor?
where it gets really hot is at battery terminals when motor goes very slow like going up hills ....probably could input 48V for short periods and motor would survive, but speed controller only rated at 36V so cannot say for sure....should have some sort of backemf/recoil recovery circuit with steering diodes on that motor to keep it cool and be able to put in more voltages
You can over power a motor for short time. Think of it as a nitro boost in a gasoline engine. If the motor has extra cooling you can do it for longer periods. It's the heat created that causes the damage.
Not so amazing it gets hot going up steep hills. Motor is from junk pile in someones backyard. Its 36v 400A rated but no brand on label. No magnets in motorit has just 4 very thick wired coils in stators and rotor too, so is coils vs coils power...it changes polarity every other firing but is dc input...this why it has. 4 big brushe copper commutaor. It is a very typical forklift (fingertlift) motor got it for 100 bucks. Look at the motor generators I build on my TH-cam channel would like to add one of these to drivetrain I am in Minsk Belarus for summer electric fiat in Seattle. Thanks for writing!
I want my time back!
putting in clutch and flywheel was not such good idea, it added weight, motor turns slower, and you can hear some scraping noises of the flywheel bolts hiting something in there.....don't know what am going to tak e it apart put in motor of my own design eventually however living in eastern Europe now....drove around in a Renault TWissy electric car in Germany for a monty - that was a blast to drive very very quick and fast only 2hrs to charge up range about 80miles,,,,a real electric car, this electric fiat more like an experimental test bed....
Direct drive on the rear axle would be ideal
So if it made this car go 35 mph, I wonder how fast it would make a go kart go...
Actually I got it up to little over 50mph on flat road, with freshly charged up batteries and no clutch and flywheel, the motor was then hooked directly to the 4 speed fiat transmission. In a gokart it would be scary same with motorcycle....batteries are heavy lead acid golf cart 12V type.
