Re: 50cc auto scooter conversion to electric (with video)

Thanks Malcolm maybe I will have a chat with the local office to see what gives and report back. I don't really see why they should be to worried about the tax class and missing out, as they would be getting my money anyway instead of nothing if the fuel details were changed to electric ( isn't all ...

Re: 50cc auto scooter conversion to electric (with video)

Hi Malcolm, Yes I have seen that section on the v5 but there lies the problem it needs a current MOT to be able to tax it :? . Im not sure if my local garage was spinning me a line or not about not being able to MOT the scoot but it did make sense what the guys were telling me, they did say it could...

Re: 50cc auto scooter conversion to electric (with video)

re: red tape I had the same deal twice now and finally got a letter back from dvla saying they won't change to electric because it would change the tax class. The only way to do it . Is to mot the bike as electric, then get the tax disk, then send it all off to dvla. I have not managed to mot my bi...

Re: 50cc auto scooter conversion to electric (with video)

New video please :) :) This project have been put on a shelf because of the stupid uk red tape.

OK Thud, I ordered the shafts you suggested, along with the needed bearings for them, hopefully they work out well. Do you think I need to harden them? I was considering getting all the set screw divots drilled in them and then hardening them along with the gears using the oil quench method. What d...

Re: RedBull's "Silent Ride" with Adam Raga

The uphill wheelie across the small creek at 1:22 mark seems to me to be good display of both torque and riding skill. The log crossing at 1:36, the uphill wheelie turn at 1:57 and everything from 2:23 to 2:37 qualify as "skilled riding" in my opinion. You need to check out some other vids of raga ...

Yep, nothing there to show us if this has the torque required for trial, and everything edited so we can't hear it. Still, I want to believe, that gives me the push to build one. :w...

Re: Issues sorting out phase timing

the way I do it ( done it) is to connect the phase wires ( just have a random guess ) the swap the hall connectors round until it runs and sounds right ( no load, low current, a small hub I would have thought should be no more than 1A wot ) if the motor is running the wrong way after you found a nic...

Re: Has anyone played with "BLOCK TIME" on Infineon Controll

Gwhy. What i am saying it yes the controler is using the voltage drop it sees and making adjustments. This is why when i program it to a lesser current setting it gets slower and a higher setting makes it faster. I made the shunt less resistance on purpos so i can run more amps not only for acceler...

Re: Has anyone played with "BLOCK TIME" on Infineon Controll

THE ONLY THING THAT CAN BE OFF IS THE HI CURRENT SENSING AND THATS WHEN IT GETS WARM IT WILL MAKE THE CA AND THE CONTROELR READ HI NOTHING ELSE. Can the chip in the controller correctly resolve the voltage drop across a piece of copper pipe 100% or maybe even the chip requires a min PD across the c...

Re: Has anyone played with "BLOCK TIME" on Infineon Controll

No both my CA and my controler sample from a section of the copper tubing before it feeds the fets so it is sampling properly and changes in settings make a difference. But now that i can program over and over because i have a permanantly attached programing cable its not so bad The voltage drop ov...
