omg did'nt think about that Now the parts are on my working place, will see that tomorrow but I'm confident. ~edit: it fitsPediglide wrote:Looks nice. I'm just worried about the back of the motor getting too close to the baseplate.
I did mine on the lathe and got a result like that, but using a diamond tip going back and forth slowly (about 2 mins a wheel) you can get it pretty smooth. You don't want it fully smooth anyway. If you get rid of the big ribs around it and any loose bits, thats perfect. You want some hollows and rough surfacing to help the glue adhere it to the aluminium tube. Otherwise a forsner bit works well, if you can get the right size.Nordel wrote:..but it's a very old machine (no CNC) and I do not think I'm able to mill a perfect circle.
I'll probably have to wait until my vacation is over and then make it at work on the CNC. Or do you guys have some nice idea?
I think that was the problem, I ''almost'' finished my board (nähh... let's call it my prototype) now, the low voltage alarm is set to 3,5v and it beeps sometimes when I'm riding hard at 3,8v.chaka wrote:Sounds like you ran the voltage down too low. I used lifep04's with a total of 60c discharge rating and I toasted a good number of them by simply riding too hard with tall gearing. You are using a 1 : 1 ratio so you are going to pull a lot of amps when getting up to speed. This causes the voltage to sag on a small battery pack, when the voltage dips severely the amperage draw goes up in order to output the wattage demand. In short, it's a bad scene for a lipo. This is where a low voltage protection circuit or overbuilt battery come into play.
Yes, i can switch them outside but will solder them together inside the motor next time I take it appart. There would be also the option for a star/delta switch but no need on a skate i think.Hummina Shadeeba wrote:Nice u hooked it up so u can do star or delta? Can u switch outside of the motor?
I think that would be possible, it's already done on some ebikes and in many industrial motors.Hummina Shadeeba wrote:If a switch could be done for star to delta on the remote that sounds great to me. Don't know if that's possible.
I have 60 cells, doubt 10S6P (=36V@60A) would stress batterys less than 12S5P (=44V@50A). I like it also to not hit my controller or motor limits wich both are 12S (for sure the motor could handle more^^). However in this case I think will get close or over my battery discharge limit:(Hummina Shadeeba wrote:I juuuust ruined a lipo velcroed to my deck, which is good as now I'm finishing my li-ion pack. 48 cells 12s4p lg hg2 cells with 20amp discharge. If ur doing the vesc why not just do 12s? Better performance and friendlier on the motor and battery. Maybe ur bms won't do it. I'm skipping the bms
