Post race motor pull down...
hall side stator is shorting to core. This is most likely a result of the controller tripping out at full throttle as the windings jerk back and forth and wear through the laquer.
Not sure if that robbed me of any power during the race as the motor pulled smoothly all weekend.
Have re assembled the second motor and will install it for the ride day at Phillip Island next week.
What I learnt at Wakefield,
advantages of Hub motors in racing (yes there are some !)
the weight of the motor in the rear wheel drastically reduces forward weight shift during braking meaning you have 2 wheels braking not like a conventional bike where you have the rear wheel floating in the air.
We only discovered this once Jon (Catavolt) finally started tweaking his Kellys and turned regen up to 50%. The effect was phenomenal, instantly the Dealim (Korean for donkey) started braking like a McLaren F1 and was easily outbraking me into turns. You can see the effect in the 3 videos posted on YouTube a couple of posts back in this thread.
In contrast heres what my bike did when I turned regen up to 50%. It was like someone sticking a broomstick in my rear spokes.
I locked up and went straight through the gravel, came in and had to turn regen back down to 23% on switch mode because when I activate boost function in the Kelly the regen brake loses its pot modulation function (????)
sounds like some sharing going on in there but the power ramping at low speed was more valuable to me than variable regen.
Riding so close to Jason all weekend I saw exactly what the disadavantges of Hub Motors are. The unsprung weight of the rear wheel almost rolls the tire off the rim in some of the corners and makes the bike slow to tip over into corners as the gyro forces are very heavy.
So now you have the Hub Motors 2 main advantages and disadvantages in direct opposition to each other.
The superior braking is something you want to design towards but the bad handling has to be designed around. Maybe a full sized 190 tire would help.
This definitely has me thinking about Hub Motors in a race bike, very eye opening considering I was totally against Hub Motors up untill now.
Under advice from a front running SuperMotard racer (Shaun Geronimi) who test rode my bike on Sunday morning in Warmup I have fitted standard genuine Yamaha front brake pads and have noticed an improvement in bight straight away.
He also gave me one of his older Pirelli Diablo SuperCorsa's straight off his Motard bike as the Michelin Power ONE was under par and both he and I saw the front end pushing and sliding in turns.
Il have to get him to ride my bike more often.
