The test setup is a kelly kbs36051 sensor commutated controller and a turnigy sk3 6364 motor with 59mm hall effect sensor board running on 24 volts.
Thanks to the people from endless sphere for their suggestions.

Turnigy aerodrive sk3 6374 149kv brushless outrunner motor.
Which hall sensors and how do they work.
I often have a project on the go and its a useful way for me to document what i am doing.
When they say sensored in the context of hobby brushless motors they mean that it has hall effect commutation sensors.
How to add external hall sensors to a turnigy sk3 outrunner.
The sensor arrangement is fixed with hall signals a b and c on the kelly being connected to signals a b c on the board arbitrarily selected for easy wiring.
Making an accurate battery meter.
However you should note that hall sensors are much lower resolution than encoders so accurate position control is not possible.
It s finally working after all the failed attempts and the reworks.
For a 7 pair 14 pole motor like the sk3 the key number is 17 14 degrees.
So the centre of each hall sensor needs to be 17 14 degrees from the next.
Opened in july 2019.
Ss461 work fine too.
I already had a feeling one of the hall sensors was damaged from when i was first testing out the motor.

August 6 2015 at 10 36 am it seems that most of the hall sensors are inset into the actual stator plates.
I was able to work on the scooter for a whole afternoon.
