Bluefangs Electric Motorbike

Hey guys and girls,   I have been building a Electric motorbike for abit now, had all the parts originally and built it up in under 5 days but due to skimping hard core on the controllers i managed to blow them up so then that started a progression of 2 months worth of waiting for parts and waiting ...

Quick Battery Question

Have you looked on you tube, there is a video of someone doing a dyno tune on his car, a mate comes up to the car shoves a leaf blower into the intake, blasts it, and the engine does like another 10% on that power run compared to the first with out the blower in the intake :) so yes they do work Its...

Reverse Trike Rego

I have been looking into Reverse trikes too and from what i have found the regulations are the same for 2f1r and 1f2r trikes with a max weight limit of i think 750kg before they are deemed cars. Looking to build something like the Peugeot 20cup trike, building a space frame chassis based on wide Loc...

Why standard GEARBOX for EV's

Realistically the standard gearbox from a car is kinda a waste for most EV conversions as you will only likely use 2gears at most, would be great to find a easily adaptable supply of cheap second hand 2 speed gearboxes with like a 1:1 and 2:1 ratio so you can have good acceleration around town to sa...

ABB motor and VFD selection

Wow, half this is flying over my head but with changing the motor from 15kw to 30kw isnt this going to double the current needed causing the motor to get alot hotter? I know you guys talked about extra cooling, but that sounds like alot of extra heat too.

Changing an induction motor voltage

I dont have many measurements atm but here are some photos, total motor length including pulleys is 550mm, width/height is 250mm and the motor casing seems to be about ~300mm. Ruler length is 600mm http://forums.aeva.asn.au/uploads/868/Photo028.jpg http://forums.aeva.asn.au/uploads/868/Photo030.jpg ...

Changing an induction motor voltage

Wow, this is really great information. http://forums.aeva.asn.au/smileys/smiley1.gif Now for a question, you took a .37kw industrial motor and multiplied its power by 4 to get a 1.5KW emotor. I assume this would work with larger motors? Atm there are 2 motors at my work that are not used at all and ...

Using two controllers?

How does the brushless motor from http://www.goldenmotor.com/ compare to the etek one? Cause to me there is a huge difference in price, ie Etek is double the cost while only having 8 vrs 7kw and weighing like 7kg more.

Light weight kit car, 4 wheel drive.

I was not specificaly looking to go 4 wheel setup, I was more looking at using hub/inwheel motors. Seeing as they are still fairly low powered i was thinking that 4 motorbike sized ones would get the desired results of a fairly fast car in a light weight kit car. But if there is nothing really to co...

Light weight kit car, 4 wheel drive.

Well with all that extra hassles that go along with dual motors i doubt i ll be building around that design. I am thinking atm that a simple mid seating spaceframe chassis(clubman with the seats moved forward) with a single motor similar to warp 9 mounted parallel to the rear axle with a chain/belt ...

Light weight kit car, 4 wheel drive.

hmm i was hoping that there would be some sort of wheel speed controller for this type of setup already which is why i have not listed one. pitty i dont have much programing knowledge to build a computer controlled system, A simple VR sensor on each drive wheel should be easy to setup with some extr...

Light weight kit car, 4 wheel drive.

Hey guys, i have been looking at building a light weight kit car, similar to a Lotus 7 style clubman. Will weigh in at about 250-300 as a rolling chassis. One thing i would like to do is electrify it :) I searched the forums for other kit car builds but couldnt find any :( I am not a fan of gearboxs...
