I changed out my esc’s to AM32 and I am wondering if the “Startup Power” setting in the AM32 config and MOT_SPIN_MIN effect each other.
What I am running into are my motors seem to struggle to start if at all and make a horrible squeeling noise.
I havent changed any Mission Planner settings just changed out my esc’s.
Here is my other post about this change…
Not a lot of info out yet regarding AM32
You need to obviously change the ardupilot parameter if you change the AM32 parameter
I found this video helpful. I’ve configured a couple of AM32 ESCs recently without issue (and one where I had significant issues - be careful updating firmware and maybe don’t do it if you aren’t 100% sure you have the correct target identified).
Thanks @Yuri_Rage , everything I see and watch/read is all about small quad fpv settings for am32 and not 15 plus inch size. I’ll keep reading and testing.
Fair enough, but I think these settings apply fairly well to slightly larger motors. 15” props aren’t THAT big in the grand scheme. I run a larger quad with 10-14” props depending on the day, and my BlHeli_32 settings for it didn’t really differ from anything I did on smaller stuff.
Disable sinusoidal start if you have it enabled. I don’t think that will help the cause. Set the kV correctly, and if anything, undershoot slightly.
These are the esc’s that I have.
This is the firmware I have and I think it may be the wrong one. It is the only option that it gives me…
I am thinking I need to do this…
If it’s taking input and producing output, it’s probably the correct firmware. My own experience with the Tekko series AM32 is similar - the firmware targets don’t really seem to match expectation. But they do work as delivered, and updating to the only option given by the online tool has been successful. Don’t get creative on that count like I tried…
DEFINITELY don’t flash an F415 target!
I see that the MCU is the f421. I am getting some really odd dshot current readings that are way off. I will keep testing. Thanks for the help.
Are you absolutely sure that they are 28 pole motors?
And why such high startup power?
350kv
The high startup is bc I was getting weird cogging then stall with a squealing on start up. I haven’t tested it yet with it that high.
Maybe I should change MOT_SPIN_MIN instead?
Set startup power to 100 and increase MOT_SPIN_ARM and MOT_SPIN_MIN by equal amounts.
I’ll try tomorrow if no rain happens. Thanks again.
You have the correct firmware. I’m the guy who refactored the guide.
In parallel I asked Holybro for a guide and they came up with
afterwards.
I run these ESCs on a 5" Quad with Betaflight and a flying wing.
Check what color your RGB leds dim out. I’m not sure if there are fakes around or if the color results by chance. On the copter I have one white, 2 green and one red.
I have not changed anything on the settings and it even smoothly spins a heavy 9,5"x5" prop without issues.
The esc’s that I have from holybro came with am32 I updated them with the latest firmware. I guess what is most curious to me is will they spin a 20in or larger prop? Everybody that I see using them or building with them it’s less than a 10-in prop. If I test the esc with the motor test feature in ardupilot vs thru the flight controller is the real test. The only difference in the situation is the esc’s. The quad had blheli32 previously and had zero issues spinning larger props.
I have 6215 24pole motor turning a 24in prop, this is my test stand setup.
As far as the LEDs, they only light up when I plug the battery in them they dim out in a blue ish color I believe.
And you have 28 poles in the settings.
You need to correct that in the AMC component editor window!
Sorry it’s 28 magnets 24 stator motor. That was a typo on my behalf.
It’s correct in the AMC.
The only setting in the am32 config software other startup power is the kv of the motor. My motor is 350kv and the software will only allow 340 or 360. I picked 340kv.
