Control device for brushless motor and control method therefor
Dude, check this out.
It is some kind of explanation about a system driving for 3 phase motors specially made it for Kokusan Denky.
This is the second time i ended up reading something about patents web sites!
It suggest something like "Rotation angle" and all things like that.
i will read it this night and see what happens.
No matter which is the answer (It is able to run both directions or not, it is able to run at variable speeds or not) i will post the results to make a first statement about the subject.
Chears.
