The latest hex file I received from Paul is SensorlessFOC.hex dated Sep 12 at 11:14 am

Loaded into the controller - OK

foc test 2 is the log file

set for pole-pairs 4

set rotor-time-constant=index 40 (17)

run the motor with the throttle signal

Motor is NOT 4 pole pairs


foc test 3 is the log file

set for pole-pairs 2

run-rotor-test

video shows a big bang - test aborted at 870, index 50



foc test 4 is the log file

set for pole-pairs 1

the last index is NOT the best, 83, but that's still low.

index 25

run motor with throttle .. lots of buzzing. Motor does NOT have 1 pole pair.



foc test 5 is the log file

set for pole-pairs 3

the last index is the best, 27, but that's still low.

index 50

run motor with throttle .. lots of buzzing. Motor does NOT have 3 pole pairs



foc test 6 is the log file

set for pole-pairs 2

Throttle fault on power-up

Check for a couple of items in config, wiggle potentiometer to get a reading. But it appears to need a power cycle to reset the fault.

pole pairs 2. run-rotor-test

Best value is last - 890.

Set rotor-time-constant-index to 49 (is it 0 based or 1 based?) Oh well, if I get the second last value it will be fine.

Crank the throttle - it appears I was too aggressive. Hardware fault when I try to slow down. Darn!


log file foc test 7

throttle is out of range on power up

cycle power

throttle is 257. Change to 482. Run-rotor-test

Powered down during test. It was cycling pretty badly. I should not have killed power - the test had completed (but I didn't realize that!) Oh well.




log file foc test 8

run-rotor-test finishes, but there is a hardware fault at the end of the test. So I could not select the highest value (1231) and test with the throttle.

It appears that there is a problem with my cheap potentiometer, used for the throttle. There are dead spots. Those spots give me 0 as a throttle value.

Sigh!

Log files attached. Working on the videos.
