That looks great! I’m working on something similar.

Mawzie · December 10, 2020, 3:20pm

That looks awesome. Did you do the glass frit yourself?

Sorry for my noob email to you by the way lol. I was struggling with the motor mounts but was installing them wrong and thought the pulley was the issue.

No worries we all have those day’s.
No had it custom by @yelnats8j

cherryflavouredpez · December 12, 2020, 3:31am

like these ones?

Mawzie · December 12, 2020, 3:34am

Those are bearing spacers, which we all use. The discussion was in regards to thin speed rings (washers) that go on either side of each bearing.

cherryflavouredpez · December 12, 2020, 3:34am

ah, thanks

glyphiks · December 12, 2020, 3:38am

Holy fuck. $50 for fucking spacers!?

Who the fuck would pay that!?

Oh, I see.

cherryflavouredpez · December 12, 2020, 3:40am

would a shim washer like this do the same job?

cherryflavouredpez · December 12, 2020, 3:40am

I got some cheaper made up (about 1/2 the price)

Davega X on the way. Received the battery today and should have this puppy running in a couple days.

Did a lot of aesthetics work today:

Loctite Motors and swapped to black screws.
Dyed Shockblocks red
Spray painted motor pulley and wheel pulley.
Wrapped motors in CF vinyl.

Got the BMS and going thru settings on FocBox now that it’s fully charged. For reference it’s a 12s6p P42A battery.

Settings help:

The unity let’s me set the Max discharge current at 120a max. Based on the calc I should have a modest 150A cont and 180a Max. Not sure if I need to be able to put it higher than that.

For the the regen setting it at - 24 should be ok?
Running 60amps on 6374 190kv motors.

Any tips for tweaking some of this?

Also does this mean the belt is to tight on the other motor?

Mawzie · December 21, 2020, 4:57am

Also any suggestions on fitting the bms and unity together? I have the unity on the heatsink and mounted by with the two screws through the top of the unity. If I were to velcro it to the top of the unity could i run into problems?

monsterbuilder · December 21, 2020, 3:34pm

Yeah, the belt is too tight on the other side. Loosen it up until it spins more freely.

Mawzie · December 21, 2020, 3:37pm

Thanks I got that figured out. I also think that the since one of the motors was running sensorless that had an impact on it.

I couldn’t get the other motors sensor wire to work so I decided to just go sensorless all together.

Mawzie · December 21, 2020, 4:12pm

So we are up and running. This looks a bit strange. Is it cause it’s running sensorless?

JoeyZ5 · December 21, 2020, 4:33pm

Yep

If you are feeling adventurous, properly setting up HFI with the VESC tool will eliminate the cogging you are seeing.

Happened to me as well,Check that your motor detection was correct, showed I was only running 1 pole. Reprogrammed it and it was perfect

chatherton99 · December 21, 2020, 5:30pm

Or that part where it’s a circle and has groups of 3 little circles that are suppose to go around the big one. If there’s only 1 group of those 3 little ones then you gotta reprogram
