Trident motor controller



On your blog, Update #19, you explain the motor control is done with Field Oriented Control.

It seems a very interesting controller. How do you manage it with your ESC ? You need to reprogramme them ? You measure the current on each phase at the output of the ESC ?

Thank you for your great blog.

Best regards,



Hi Frederic:

Trident uses a custom-designed ESC that is integrated onto its main circuit board. It is very different than the Afro ESCs that are used on the 2-series OpenROVs.

Yes, we measure the current on each phase leg as part of the Field-Oriented-Control process.



Hi Walt,

Thank you for your response.
