Tried with and without a resister on the temperature wire, just in case there was a glitch in the software. But it still cuts out.
The other day I had everything set to max fun and was doing about 40mph (no speedo) and when I shut off it didn't just cut out, it locked the back wheel for a second...
Well I tried increasing the max phase current to 300A, but that made no difference.
All the connections are good.
I've tried every permutation of e-brake and regen.
I've tried running the battery down.
I've tried all sorts of setting including no field weakening so it doesn't go too fast...
Seems to be getting worse. Virtually every over-run situation (shutting off) causes it to shut down.
Thanks for the software Minde. I managed to turn on variable regen, but as soon as I went back to the mobile app, variable regen vanished again. The PC software seems to have made the motor...
My slow EV to fast EV moped conversion is going reasonably well, with some teething problems.
It now has a Sabvoton 72150 and 20s7p pack and it goes like a little rocket.
However, at the end of a fast section after closing the throttle, the Sab' cuts out and needs rebooting.
Is this a common...
My understanding is that field weakening is necessary to run a motor above it's rated speed by reducing the magnetic flux.
In a brushed motor the field winding current can be modified to reduce the magnetic flux, but with a brushless motor with permanent magnets, some electronic trickery is...
Sorry I missed your questions. I don't seem to be getting notifications.
Thanks Amberwolf. Specifically, this is the phase converting connector - https://www.aliexpress.com/item/32796266176.html
Does anyone have a link to the latest PC software for the 72150 please? I need more than just the...
For the sake of finishing this thread off.
I am up and running now. And flying! :)
The halls were fine, but the motor was a 60 degree which the Sab didn't like. I fixed that with a little phase wire switch that converts it to 120.
I'm now testing all the settings. Haven't managed to get the...
AH yes. Thanks, I didn't notice that photo.
Anyway, the good news - it works! :)
I had to swap the blue and green wires coming out of this converter then it tested ok and I could begin the process of understanding the software. I have no idea what has changed, but now it saves the settings :)...
