Need help identifying sensor lines on BLDC motor

I'm trying to develop my own hardware to control a robot mower I have. It is an Ambrogio L210. The motors for the wheels are BLDC which have 6 sensor wires and 3 phase wires from each motor. (Red, green, yellow, blue, black and white for sensor) I'm trying to determine how they could be wired. I'm guessing that they are coming from Hall Effect sensors. In the picture, the top three cables of six wires go to the 3 motors (wheels and blade).

So what you are saying is that 5 of the sensor wires are for the hall effect sensors and the other wire is for something else?

If there is six conductors for the sensors, i.e., two for each sensor, they could be passive devices, Try a (V) meter on each pair and spin the motor see if it generates a voltage.
If they are passive, you should see the 'blip'.
