Brushless dual 6kw ALIEN Power system - electric longboard

Well my large bracket would fit or you could put the threaded grub screw home in the middle of the teeth.. And just have the boss stick out of the end of the shaft . One concern I do have is that you are only using grub screws to drive the pulley .. I really think you need a keyway to transmit the power .

However, I'm facing one problem. as shown on the pictures below, there is a clip at the base of the shaft and the bore on small bracket is too small to fit this clip...n

That clip is very thin. You'd only need to take off a small amount of material around the hole to provide clearance.

Find a machine shop nearby, take motor and mount with you, and tell them what you want.

Should be cheaper than shipping.
 
Or cut and drill a thin piece of shim stock to fit between the motor and mount.

I have the same motor and I suspect that's what I'm going to do. A 1/16" thick shim should be sufficient.

Thanks!! think i'm doing with your idea of threading grub screw home in the middle of the teeth with hole drilled into the shaft for set screws..

how do i machine the motor shaft for keyway to work? I'm new to all these machining stuff and have not seen how keyway fits on a shaft.. if you have a picture it would be very helpful
 
the motor need dismantling really- then you use a milling machine to mill a keyway in the motor shaft and the key sits half on the shaft and half in the pulley
this is the best photo i have..zoom in on the pulley /shaft

I see.. Now I understand what you are talking about. However, I don't think I can do such a job.
I will just try with set screws drilled into the shaft and see how it goes.
 
ok- well if you put the pulley on the shaft and then drill trough both parts together and just machine into the shaft maybe 2-3mm it may be ok..
 
Yes. The two piece design gives two advantages, one is ease of manufacture and the other , as pointed out is for adjustment of the belt tension.

Grinding a small flat spot on the shaft seems the most often suggested improvement.
 
Hi !

Long time ago (1 month) i started to mount a new board with drive and power system ! I just received yesterday my alien power esc (dual) and the two motors.
I can't connect to alien esc with prolific drivers and the APS.exe program. Hope someone here has an idea what is problem.
I installed prolific drivers on 3 PC without problem. Port is OK (not always the same). I starded APS.exe, and the software says port is ok, and please me to connect the esc with the 4 wire (with attention to colour of course). But no response, i see nothing on the program, same on the 3 PC...
Before i start all the connection on the board i will be sure that the esc is ok.
I see on the prolific driver on the red and black wire a voltage of 5V. So it must give the current, without another battery.
If someone here had one time the same problem and can help, i thanks very much.

With bests regards
Yann
 
I had a similar problem to start with . You must make sure the prolific driver is running first then open the APS . From experience it can take a few goes at it .. Maybe give Bruno a email ?
 
Hi. Please email me on ES or on my personal mail. Don't use the Alien website. It is not operative yet and I can't receive any mail from there. Sorry about that. Regards
 
Huge Thanks to Beetbocks and Brunotollot! I found this forum after checking out Boosted Boards and decided to try and make my own.

I got the single drive kit from Beetbocks, and Alien Kit setup from Bruno.

I took my first ride last night, and really fun. I would highly recommend these kits - very easy to put together, and Bruno was super helpful helping me understand the electronics.

Here is my setup:

Single drive kit from Beetbocks
120A Single ESC Alien power kit, with 3kW motor
Turnigy 60v SBEC
Zippy 8000mah 5S lipo (just one battery for now)

Add some trucks, a board, and radio gear - and off you go! Seems great so far, the single drive gets me moving from standstill just about (but better to kick) and uphill seems fine.

Thanks again everyone. Now to refine my look and enjoy the ride :D
 
Thanks Ben. Feel free to ask for any help or questions. Regards
 
Here's a pic, nothing too exciting. Everything wired up, just getting some placements for the electronics/wiring. Need to construct a nice case for this lot!

One thing I'd love is to get the deck height down. Feels a bit high for me, and I'd love to get everything closer to the floor.

I guess the motor bracket would need adjustment, and I'd need a better deck to stop wheel bite.

Any thoughts on that Beetbocks?
 
well yes- that is kind of the problem with hanging a larger motor under the deck,I could change the motor mount angle to give a lower ride but then the motor would be more likely to being damaged by kerbs etc.especially as its an outrunner.
as you say a deck with wheel wells would certainly help..and maybe slightly thinner risers?
The one thing to consider is that's its not a deck meant for pushing like your probably used to..its powered now so the lower pushing height is not really required..

Okay, I thought I'd take another look at that nice board. Something to look forward to ...

But ... what's wrong with that picture?

Glad I'm not the only one that does things like that. :)

Thanks for the photo!

Hi

I just saw that there seem to be more than 3 wires entering your motor. Do you have hall sensors inside your motors?

regards,
