Autonomous Rover Build - Need help with Sensored BLDC motors

I am in process of building an autonomous rover, I am using sensored BLDC motors from another rover. This has hall sensors (a total of 8wires coming out of the motor), but I have brushless ESCs which only accept 3 wires, So I have connected M(a), M(B), M© from the motor out of the 8 wires with the three wires of the ESC. I have ignored the other 5 wires[Hall(a), Hall(B), Hall©, GND and +5V]. I am trying to connect now test my motor with my ESC by plugging the ESC 5V signal and BEC cable into the Pixhawk and run a motor test on my Mission Planner interface.

But I am not able to spin the motor, is there anyway someone can help with the build? If there’s no way the sensored BLDC motors work without the Hall inputs plugged,

I have ordered a sensored BLDC motor driver, now I am not sure how I configure it with my Pixhawk…

This is kinda urgent as I have a lot of other stuff to do post this.

I have used here two of those drivers (finally the smaller version of it). Basically, you have to connect (and supply) the three Hall sensors to the driver and, if using them, two of them as WENCx signals (they are at 120º, but that does not matter), in the correct order.

First, verify connections with driver and motor only (no FC).

Hi @Webillo is there a way I can contact you?

Can you maybe drop me your email address and we can discuss on it further. It would be really helpful for me.

Thanks for responding man!
