Hey kids.

I am moving on from dual 6355 170kV to dual 6374 190kV(Flipsky Sensored Motors)

Can anyone recommend current settings?

I an running dual FOCBOXES over Canbus. Using Ackmaniac.

I have a 10S6P 756wh battery, with charge only BMS.

I was planning on running sensored BLDC. had some issues with one of the motors last night. did not do too much trouble shooting. It would run detection fine, but when setting the PPM it woudl not actually spin. it would just wine. it ran fine unsensored.

when it seemed to run fine unsensored i had set each Focbox at 80 motor max -40 motor min 40 battery max -12 battery min 32 battery cutoff 30 battery cutoff

I weight 210lbs(95kG)
plan on running 107s 18/38t or 18/36t

with the 6355 170kv motors. it was all the same(18/38t) and i was getting top speed at most 32mph(51.5kmh)

Discharge only BMS? How do you balance while charging then?

80/-40 is ok, I would consider 60/-60 for a more linear throttle.

I think he meant charge only, I make the same mistake all the time :).

**charge only…

So I was under the impression going to the 6374 improves breaking. does the -60 make the breaks even stronger?

and when you mean linear do you mean a similar increase from start to top speed?

i kind of like the punch feeling.

I have heard that, but in my experience it’s the same. The only major difference is mass, meaning it stays cooler and operates more efficiently on heavy loads (meaning my fat ass :slight_smile: ).

I mean accelerates and decelerates at the same force at the same trigger position. Even with a throttle curve, assuming you have identical top/bottom curve values.

Try this, set your motor max at 60a and your motor min at -60a, set the throttle curve to the values in the screen shot below assuming your using 2.54. If you using 3.02 use -20/-20 nominal.

Then you can adjust up and down from there.

Ohhh doggie, I have been meaning to mess with the throttle curve thing…

sorry, i don;t know what 2.54 or 3.02 are?

Those are the firmware version of the @Ackmaniac VESC firmware. The major versions are 2.54 and 3.102. The throttle curve is defined differently depending on the firmware you are using.

Ok. I went 60 -60. 40 -12 on battery and set up the throttle curve. I could not get it going sensored. Messed around with moving the phase wires and got one motor going sensored and the other one would only work sensored spinning in the wrong direction and the wizard could not change the direction… Weird stuff. They sound good unsensored. Off course it is raining so I have to wait a couple days to ride.20190312_191942

Well. I’m sure not smart enough or patient enough to figure it out. I opened it all back up. Reprogrammed the Focboxes. 1 worked sensored on the first go. 2 not so lucky… I tried all variations of the phase wires and it would detect fine Everytime sensored. But when it came time to set the ppm it would not run right. A couple would run stuttering. A couple would not run. One the motor would just whine… And one worked fine but was going the wrong freaking direction. So I ended up leaving the 2nd Focbox unsensored. The master is running sensored. Ground is wet right now. Will see how it goes tomorrow
