Can anyone familiar with Carvon hubs help me identify my problem?
Setup: I’m using Dual Carvon 2.5 hub motors with 2 Ollin 4.12 Vescs using a y splitter servo cable to connect to the receiver (not using canbus cable). I’m also in FOC mode.
Issue: One of the hubs spins sometimes. When it doesn’t it just makes a high pitch squeaking grinding noise.
What I did (I’m dumb I know) Everything was great but I thought the trigger on my Gt2b was a little too sensitive. I was messing with PPM app configuration to get more range. In doing so I must have accidentally hit “read default configuration”.
I found out something was wrong when one motor was significantly louder. I road one block and turned around and I lost brakes.
When I checked the setting on the vesc I noticed it was set back to default motor configuration with BLDC.
I reloaded the firmware and loaded the settings when it worked. Motor detection for FOC works every now and then. Now I get the noise on one motor and it just vibrates and squeals. No Fault code.
I also noticed the servo wire was loose on one of the vescs. Since I have been opening and closing my incredibly tight enclosure. I think the servo wire may have broke. So I re soldered a fresh y split servo wire. There also may be a slight possibility I connected the servo wire backwards, but really don’t think so.
What did I do? Did I…
- Break or stripped something in the hub motor
- Blow something in the Vesc
- Getting interference from motor wires.
I will try post a video tonight.
