This was a very interesting presentation and because of Tinmans motor he built I almost understood all the man talked about. The motor this man built is switched very fast on 2 sides with a magnet shunt (my words) to the motor which does not let the core pull against the magnet as it leaves the coil. It is hard for me to explain it but I understand it.
