Bike Update - Newbies first bike, to much power!
So in the quest for more power, I bought a 36-fet greentime controller(100a). I kept blowing my 18-fet and I didn't want the controller to be the weakest link in my setup. Well unfortunately after I installed the MASSIVE controller... I found the next weakest link in my build:
Axle failure, Sorry for the HUGE image (right click - view image in new tab).
I had taken my bike out on a few test runs and was on my 3rd commute into work with the new controller. I grabbed a wrist full of throttle from a dead stop and put all my weight on the front wheel to keep it from flipping me off. Then all of a sudden I lost power and came to a stop. I figured I killed another controller because this was the exact same spot as where all my other controllers have failed. But upon further investigation, the broke axle actually shorted out my phase wires and blew the controller.
For everyones information, this motor was NOT
from the Zombiess shipment and I had made some modifications to the axle for upgraded phase wires (i'm a noob, this was stupid).
This is the areas that I modified. I believe the metal i shaved down from the yellow areas had no effect on the failure but I did some light filing in the wire channel (in red). I believe this is the reason my axle failed. I didn't really feel like i removed much material in the wire channel... but when the axle isn't very big to start with... removing any is detrimental to it's life.
So now after this expensive lesson... I'm wondering where I should go next.
New Axle built by a local machinist?
- I have no idea how much this will cost. I dont' know where I can source an original Axle... Zombiess doesn't have any.
New Cromotor in 16/24 inch rims?
Mod a crystalyte HS and live with a 18fet controller and low settings?
I'm open to suggestions, because right now... I'm feeling pretty defeated!
