What is the Hall sensor MTPA?

0693W000002liptQAA.pngWhat is MTPA in the MC workbench speed position feedback management --> Hall sensors? This is NOT the Maximum Torque Per Amp, I believe. Any reference for this?

Thanks for reading.

Hi,

It seems to be some kind of interpolation algorithm to estimate the position of the rotor based on the 6 ticks (rising edge and falling edges) of the 3 hall sensors.

They talk about it in a ST Video at 16:30 - https://www.youtube.com/watch?v=dt6bGpykerE

The question has been moved from the "STM32 Motor Control" section to the "Motor Control Hardware" section (the question is not about the STM32 MC SDK). 

Best regards
