I'm wondering if your sensored motors use a magnetic angle encoder or 3 hall sensors?
Very interesting either way.

Hi Drifter,

So far I am using two separate commercially available motor/ESC combinations. The benefit of this approach is that these combinations run correctly straight out of the box. The disadvantage is that they don’t come with diagrams showing how the sensors are wired inside each motor. That is a task for my oscilloscope to explain to me!

Learning so far:

The combination with the 4300KV sensored motor has a six pin sensor socket on the motor casing but only four pins appear to be electrically connected. This is likely a single Hall sensor configuration.

The combination with the 5500KV sensored motor has a five pin sensor socket on the motor casing with all pins electrically connected. This appears to be a three Hall sensors design.

As I say, all to be checked out in due course via oscilloscope waveforms - and BTW the DRV10970 manual has a nice instruction on how to identify sensor phase versus motor winding phase when building new ESC hardware.

Meanwhile I can proceed to track level trials with both motor/ESC combinations without needing to address sensor configurations until I progress to the DRV10970 based digital decoder designs (my stage 3).
