Large Sensored Outrunner in a chainsaw? - 12.10.2015, 09:11 PM

Hi Guys. Long time no chat.

I just stumbled across this and had to share.


I remember all the talks about outrunner motors and if they could be made sensored. Well Ryobi is using a large sensored outrunner to power chainsaws now.

According to this write up it is a 63/54 type sensored outrunner 300kv.

This really makes me want to get one, dissect it and start getting creative! :)

The sensor board only shows 5 leads?

How can this be adapted to run on popular sensored controllers using the 6 pin connector?

Is Johnrobholmes still around? LOL

Chime in guys. Let me know what you think.

I think it should work with most ESCs, as far as I know the 6th pin is for a temp sensor. Usually its three wires for the sensor signals and +5v and Gnd to power the sensors.

I have read on the endless sphere forums that there are companies that make sensor boards for popular 63mm outrunners, just forgot the name, but I can look it up when I have time...

Depending on how much power you need it might also be worth looking into the VESC open source ESC for that type of application.

Edit: Was easier to find than I thought:
