Re: Scootabot

Swingarm welding is done, good clean welds just need to cut the old shock mount and brace out and clean it up.
This was a 6 + week wait to get done, not stressed though.. nice to move on to the next stage....

Re: Scootabot

playing around with bar mount ideas ..i like the 45 deg idea so im going with that.
Single leg swinarm mounts done , simple but effective , might reshape them a little to look better.
So waiting for swingarm welding then i can mount motor and attach to frame for a mockup :D
bit by bit its happening.

Re: Scootabot

Droupouts aligned for welder , This method ive used before on my bike, clamping the swingarm pivot and the flat bar on a extrusion should keep them nice and straight, im going to stress this to the welder... this is dam important to get right .

Re: Looking for Scooter Hub Motor

bwinkel25 try these people. They even state magnet/stator width ..best is 60mm i think.

Re: Scootabot

Went for clamping droupouts , they have been reliable for me before in alloy at 22mm wide @ 7--10kw power. This time i went 30mm wide without axle nuts, just relying on clamping force , should be ok at around 7kw They look a little overkill but this is a good area to have some over engineering . 8) ...

What is the top speed , tell us more about custom motors ,magnet width / stator width / stator diametre looks like 11 inch tyres ? And performance, what is the voltage and what is your max kw output at th...

Re: Scootabot

ITS TIME! Swingarm time that is, got some billet laying around so im either going to go with clamping droupout or slotted with bolted end cap....
The trick is a deign that fits the bill and is the easiest for both welder and machinist resulting in a cheaper outcome also , stay tuned.

Re: Scootabot

As posted earlier concerning the 10mm misalignment of stator to magnets, i also had a axel droupout offsett. Looks like my hunch was right , after reinstalling stator 180 deg ive now got a very good stator magnet alignment and a centred axel. Quite shocking the manufacturer couldnt even assemble the...

Alex What is the stator diameter in mm , 100mm? on that 60mm wide stator.
The last rewind was 7turn i think .?

Re: Scootabot

Front corners cut off getting rid of the weak welds ..looks better and stronger to boot.
After re cutting front down tube [ fork rake ] i hand filed mating surface so the fork/ wheel is perrrfectly aligned and i will hold it in place while welder tacks it.This is the most critical part now.

Re: Winter Project... Design and Build an eScooter

Nice scooter Roncat
That qs hub should be more than enough torque , what is the magnet width 35/40mm ?
If so cant see any reason why you couldnt give it 8kw burst :D .
