.....
I already mentioned that it was for braking in my earlier post #8 further up.
I assumed I did not have to repeat 
(example of how that motor works & could work)
I made a few typo's as well
We don't blame you.
I just tried to clearly explain to sairfan1 the details of how the motor works as we are in the beginner section
It doesn't matter who said what first.
