I went back and created a conservative motor profile for the EMAX 1106/6000 from values measured independently to:
Back in the motor work bench, connect to the board and run Start Motor - the motor moves slightly and starts.
In the advanced tab - set the Speed controller to 10000rpm and 10000ms. Press Exec ramp - nothing happens - the motor does not run. Note there looks to be a speed feedback in orange warning - why?
I am running my power supply at its maximum 15v - do I need "3s" (21v~)? The motor is a 2s/3s motor, does the board needs this level of voltage?
Please please improve your documentation. Start with a simple diagram that describes the workflow. Provide more info about errors. Fix the UI. It took me a while to even find the Exec ramp.
What would you do if you were me to get this to work?
I set the "Nominal dc voltage" to 8v. and reran. The motor tries very hard to run after start motor. After a couple of secs this appears - Speed feedback
What does this mean?
Thinking that the 5.Y wb might yield better results ... I started with the 5.Y motor profiler and had some success.
The profile never finishes - it moans about taking too long and the speed limit being too low or too high.
More to report - first motor profiling.
I grabbed another 1106 emax drone motor (4800 kva) that has a slightly higher impedance than the other one and grabbed a 5amp psu. I made sure I updated to the 5.4.8 and 6.1.0 mcwb.
The 6.1.0 wb's profiler (ST Motor Pilot V1.1.3) is a step backwards - there seems to be no way to find the board and it's unclear what needs to be typed into the search fields to find something - more about the 6.1 wb in min ...
The 5.4.8 wb profiler mostly works. Setting as follows:
pp: 6
rpm: 1000000 (yes that high)
Apk: 2.7
VBus: 12
It seems to hit the motor with the full amount of current (and makes it very warm) and reports .8 ohms and .03 mH, and then runs it up. It reaches about 33,000 rpm consuming about 1.3 amps, at some high percentage complete and then seems to reverse the motor and do it all again before stopping at 96%-ish complete and complains about taking too long. Answering the prompt to continue restarts the cycle running the motor at 40% - it never completes whatever changes are made. ARGH
Is this a bug? Can the timeout a set bit higher? Is the rpm max value being scaled by 100? (The only way to get to 30000 is by making this value enormous)
Now on to the code generation with the 6.1 wb - I am pleasantly surprised to find the 6step seems to work - this is more than adequate for my needs - however after getting to the last step and asking it to open in ST32CubeIde - IT FAILS.
If I go an manually open the project in STM32CubeIde it will open however it appears to me to have not generated all the code - there is no 6step lib for example. I am going to do some more testing later and will have more to say.
All in all 6.1 looks like progress - so well done ST. Please test your code 🙂 I would so love this all to work. It's got promise - but it's not there yet - at least for me.
