Understanding brushless drives

For students of brushless drives for multirotors...

I recently made some validation measurements after reconfiguring the brushless drive used on one of my quadcopters.

The upgrade involved resolving a problem with SimonK compability, the solution in this case was simply removing the rather large BEMF caps from the ESC.

This 300+W input power drive is quite low cost, ESC+motor+propeller were around US$30 total... so this is budget hardware.

The measurements and write up are at Report on Hobbyking 40A ESC 4A UBEC 9261000003 / BC3540-14 brushless drive #2.

Note the very good fit to the first approximation models, an indication that the system does not contain components that are misbehaving.

Exactly like BLHeliSuite... probably not.

AVRDUDE and an appropriate ISP adapter to read unprotected memories.

AVRDUDE and USB Linker can read flash if you have the SimonK bootloader installed.
