Hi guys,
Finishing some lose ends...
My temperature meter, for my motor, is 100% finish.
Meanwhile, I receive my front light.

Luis.

 

[soaresdacosta]

Still making the last connections...
My on/off button is finish and my pre-charge is finish too.
I'm going to start playing with phase and halls combinations.

Luis.

 

[soaresdacosta]

Power on, for the first time...
Still not got the phase and hall combinations right...just try for 10 minutes.
Very happy with my pre-charge, connect the negative line, push the button for a few seconds and then connect the positive line. Not even a trace off a spark.
My on-off switch, work perfect too.
Next weekend try to make the connections right. Just going to read about that, here on the sphere.

Luis.

try this first - i always use it to get right hall combinations real quickly: http://www.endless-sphere.com/forums/download/file.php?id=7583

Hi guys,
After I read about halls and phase combinations, I thought, find the correct sequence its gonna be fast...
One hour later, I though something is wrong... And it was...
I put my "lyen-tester", and found one hall damage or the wiring...I cant believe I thought I was test drive today...
A ton of work is waiting, I already take the motor apart...

Luis.

 

[soaresdacosta]

Ok, bought some halls from lyen.
After some tests, the problem was a cut wire...
Change the halls wires and put the motor back toghether.
Everything run fine. Test the phase and halls with my lyen-tester, all ok.
Now...again....lets try some combos and make a test drive.

Luís.

Hi guys,

After another broken cable, this time a hall cable, coming from the controller...i run some combinations, and everything runs fine.
Just waiting for my torque-arms, and finish my battery.

Luis.

 

[soaresdacosta]

Hi guys,

After 3 months, my torque-arm, finale arrive... Not 100% happy with them, but for now, that's it.
Install my "magicshine" light, and I have a new button for my "regen".

Luis.

 

[soaresdacosta]

Start to put my "charging-station" together.
24v power supply and a 1000w powerllab6 charger.
Need to build some cables...

 

[soaresdacosta]

Continue to put my "charging-station" together. I believe, the best way, is to buy a box, like a tool-box, and put everything inside...power-supply, charger, cables...
I have a difference in voltages between my "cell-log" and charger. I believe the charger is more accurate. Right ?
Very happy with the charger, extremely fast and some nice graphics and data to look at.

Luis.

 

[soaresdacosta]

Doing some test-drives, to see if everything is ok.
This thing is amazing...lots of power.
But...always a but...my controller signed off. After some tests, i have a short on the yellow phase. I was pulling betwen 1500 and 2000 watts, wen this thing faill. Is this that fragile ?
Well, im going to try to repair the controller. If I cant, is going to lyen. ..2 months out.

 

[soaresdacosta]

OK, I buy a new 18x4115 controller.
In the meantime, I try to fix this one. I bought a iron with an integrated pump. Not very powerful, but did the job.
I bought some 4115 feets, from a German company...but made in China.
I been able to remove the mosfets, and install the new ones.
Still don't power the controller, but at least wen I connect the phases, the motor spins with no drag.
If didn't work, I will send it to lyen.

Luis.

 

[soaresdacosta]

I receive my controller from EM3ev. Very well packed.
I never receive a package that fast. I maid the payment on the 10 of June. Today is 19. Incredible.

Luis.

 

[soaresdacosta]

Hi guys,

Incredible... My repaired controller work. (I'm not an electronic guy). Now I have a new, spare controller.
There is some adjustments to do in my bike. I need a good torque-arm for the gears side. After that, I will try the regen. I already have a button for that.
If I start this build today...go with full suspension.
This motor have lots of power and no increase in temperature...for now.

Luis.

Since I have one spare torque-arm for the "disc" side...I try to adapt for the other side.
This is a temporary fix, until I find a local company.
I think the result is acceptable.

Luis.
