External hall sensors on the turnigy aerodrive sk3 6374 149kv brushless outrunner motor doug says.
Sk3 hall sensor.
However you should note that hall sensors are much lower resolution than encoders so accurate position control is not possible.
I began using honeywell ss441a sensors because i know others have had success with them however i later switched to latching ss460.
One thought on internal vs.
I appreciate that notching the plates will short some of the plates out but i think the shorting is.
This is a feature we are looking to support one day you can subscribe to the issue here to be notified of updates.
For a 7 pair 14 pole motor like the sk3 the key number is 17 14 degrees.
This blog is a page to collate my thoughts and maybe help others along the way.
Ss461 work fine too.
Thanks to the people from endless sphere for their suggestions.
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.
I was able to work on the scooter for a whole afternoon.
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.

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.
Completed boards with sensors single completed board with sensors bare pcbs without sensors mounted on example motors 63mm c style 59mm sk3 63 style 80mm c style using hall effect sensor adapters example sk3 63 motor not included with hall effect sensor adapter and board.
Which hall sensors and how do they work.

So the centre of each hall sensor needs to be 17 14 degrees from the next.
How to add external hall sensors to a turnigy sk3 outrunner.
It s finally working after all the failed attempts and the reworks.
Making an accurate battery meter.
I often have a project on the go and its a useful way for me to document what i am doing.
