nice car, surprised someone hasn't bought it yet

Anyway, buy my stuff!!!

you guys are really up with the tech stuff

cheers - thumbsup

BLDC motors ARE AC motors. Really, they should be a class of their own. High torque, high speed, regen braking, but use rare-earth magnets which are very expensive. BLDC is the brushless DC motor i mentioned in the first post. i did a bit more research, and it appears i have been using a BLDC motor...

i have heard a whisper of some debate between DC and AC motors - my intention was not to add to it, but rather do some research and then see what you guys thought of my findings (or if i had missed anything). and also possibly help others because i could not find this subject with search. DC Motor [...

Depends what motor your looking at using. Most AC types of motors (esp induction) have poor efficiency at light torque loads. Considering to maintain a certain velocity with a defined drag you need a certain power, if your motor is not sitting above ~40% of its rated torque, decreasing the speed of...

is there a way of directly linking to a specific post in a thread (cause i can't see anything around a post that i can grab a link) The little blue circle (starts off as a yellow star until read) to the left of the subject is a link to the topic; you can use your browser's right button to get a lin...

hi there, even though i have been a member for a while, i have really only just gotten involed in the forum - and i seem to come up with questions on occasion - so i thought i would post them in one place. does this forum have tapatalk?? (this allows you to access the forum on a phone - did a search...

More efficient at the same power, at higher RPM. I.E. you can flog a motor with extra voltage / current to get more torque, but it costs you efficiency through resistance losses etc.. If you instead spin it faster with less torque - same power out, fewer losses. had a thought while i was asleep (an...

If you instead spin it faster with less torque - same power out, fewer losses. ah, i see, just started a new thread...

woody said this to me in another thread, which sparked me to do research in the area of engines. B) Petrol cars change gears at high RPM as the efficiency of the motor is better at lower RPM (also quieter, longer life) electric motors are more efficient at higher speed usually The below two quotes w...

thanks woody, questions answered

wasn't what i expected though - i guess i am still thinking in terms of petrol engines...

was really surprised that electric engines are more efficient at higher RPM - looking into it now

hey sascha, if you really like your ev, why not bring it over and register it in NT

or are EV restrictions different for each state ?

that is really impressive

questions about gearboxes first some posts i have come across say it is better to keep the gearbox, even though it does cause a bit of a drag and you may only use one gear. (the point being - if you ever get stuck at the bottom of a steep hill, you can change gears). i would have thought that when y...

really impressed with your conversion,
i like how your a perth ite - me being from down margaret river way.

thanks for documenting your build - at the moment i am just in the research stage. your documentation helps a lot, cheers

just a observation - it might be beneficial in the "for sale" section to close threads once an item has been sold (or some other way to indicate it has been sold - before you open the thread) also, only because i come from WA, it might be good to have a location for the item as well (before you open...

wow, i figured the batteries would be on par with the rest of the car costs.

thanks guys really appreciate the help - i need to start putting a list together and find a car (with a blown engine).

thanks for pointing me in the right direction - will browse the forum

You don't need 2 motors either. There are plenty of eV's that are single motor direct drive. That'll cut down on complexity and cost. 4wd's come in a dual cab - 5 seater. deleted - which is on the coast. a 4wd would be great (because of where i live) but i find the maintenance on such vehicles to b...

Hi nazar, Nothing is unrealistic at this stage! If you said you wanted to do it for $10,000, then I'd say you were being unrealistic. As you have considered DC, then you are certainly going to be in the more affordable realm. A 4 seater sedan is certainly doable. I would suggest you'd need at least...

gudday there, i did some research a while a go, but am now ready to buy/build a EV - but it will depend a little about cost effectiveness/price.. i converted a pushbike to Electric (using lifepo4 battery) - the battery cost more than the rest of the kit :D what i need/require an EV that will hold 2 ...
