Last year I build my first electric longboard, with inspiration and information from you guys! Thanks for all the amazing builds and information avalible on this forum, its amazing
I have been riding my board for a year now, and borrowed it to my cousin a few weeks ago. He road it for a few miles, and of course fried all the electronics That gave me a new opportiúnity to create something new and hopefully better.
So far my build will contain:
1 Turnigy SK3 6374-192kv motor
30 Samsung 25R 2500mAh (10S3P)
1 40A 10S BMS
1 Vedder Antispark Switch with 40A/50A fuse
4 83mm ABEC 11 clones
Custom remote with NRF24L01
A VESC 6.4
15T and 40T HTD pulleys and belt
The deck is designed in Inkscape, and milled out with my X-Carve from Inventables - a most usefull machine! The deck is made of some glulam I had in stock.
It’s looking oddly similar to my build so far. You might try and router out the edge of the deck a bit on the underside to give it kindof a wheel well. It’s been working out really well on my. I’ve got 97mm wheels and only 1/4 inch risers
It seems like this has been addressed and fixed w/ the VESC 6. Where the VESC 4.xx was pretty much guaranteed to kill the DRV chip over 60k ERPM’s (thanks to @Chaka for calling out this limitation and sharing here).
I just read a pretty lengthy post by Ben on his forum regarding the VESC 6 Beta. Getting close finally! And some motors over 150k ERPM it seems w/o issue. Much higher amps possible, and just seems a ton more robust!
The possible downside if you were going to build your own (you made your own deck - i’m guessing you might try reflowing your own VESC) - Vedder’s BOM/Gerbers aren’t yet available during the “Beta” . But you can see if there is room to join the beta group by contacting @trampa (Frank at Trampa) to get on the list. Trampa being in the UK, and you in Denmark - it should be a bit faster for you vs those of us in the states.
If you go printed pulleys - you should go 15mm wide belts for more contact, and hopefully you are light. Being in Denmark - i’m also guessing it’s pretty flat where you ride?
I had a single 9mm setup w/ printed wheel pulley for my GF - worked OK. Nylon IIRC, not PLA, but while she could ride it - it would skip terribly for me no matter how tight i ran the belt. Not just at faster speeds… So while it can work… I would still go w/ Aluminum if you can. Look for @Titoxd10001’s 15mm 15/40 setup if you want to gear down (less top speed, better accel and torque) w/ some nice aluminum gears that won’t break the bank $ wise. Unsure if shipping to EU will be prohibitively expensive though…
Thanks for the tag. @Deathjunior I have aluminum 40t pulleys designed especially for 97mm flywheels. I also have steel 15t 15mm pulleys. They will be available for purchase today or tomorrow shipped directly from Europe at a very reasonable price.
I’m good lol I run cnc aluminum wheel pulleys I just use an abs 3d printed spacer to make them work on my 97mm flywheels. My motor pulleys are steel. I’m going to rework my motor covers and print them from pla in order to investment cast them in sand.
I have just recieved my 40T and 15T pulley from @Titoxd10001! Looks great, and fits my ABEC11 clones perfectly - thanks, you just saved me a lot of enginering !!!
Thanks, but I have been working on a motor mount myself ! Just finished the 3D-sketches today, and been trying to carve the design in aluminium on my CNC. It came out very good, however I did not have the time to finish it completly.
So, it’s been awhile since I had the time to work with my board, however since the VESC 6.0 just has been released for Beta, I simple had to finish the mechanics (motor mount etc.). Instead of the aluminum motor mount I had been working on, I decided to try something new. I recently bought a 3D printer, so I thought it would be fun to try and make an all 3D-printed motor mount. And I came up with this design (inspired heavily by the one from DIY).
It consists of to parts, heavily interlocked and reinforced. The locking ring fits perfectly on a caliber truck and is tightened by one 5mm bolt and locked in place with another 5mm bolt. The whole motor mount fits right over the caliber-ring, and is locked in place with 1-5 4mm bolts. To make sure the motor mount doesn’t bend I have made room for two solid 3mm*80mm steel rods, that slides in from the tip of the motor mount.
Sooo… I printed it with some high quality carbonfiber reinforced PLA in about 4 hours, and it fits perfectly
