Adding hall sensors to brushless outrunner motors


(Sebastian Schürmann) #1

Hi,

is there anybody here who knows how to do this, which sensors to buy, etc? I would like to use two brushless outrunners with sensored car escs.

The encoders mentioned in the wiki are grounded to the Pololu motors but are discontinued for a newer model with endcaps.

You may be able to use https://www.pololu.com/product/3499 and mount to outrunner case. I think those are the highest count per rev. they make. Not sure how fast a rover your making as they do make a few stand alone encoders

Thanks for your reply and sorry, I did not make clear enough what I am trying to do. I want to convert two sensorless brushless outrunner motors into sensored brushless motors, to make them start and run smooth at low rpm. I am using blheli ESCs right now and already got them configured quite good, but sometimes, the motors just start to vibrate.
After playing with google search terms, I found a site where the theory of sensor placement gets explained really good:
