the drawing above has its regauging magnet underneath the core in the far right illustration with its polarityy backwards.
IT should be S on top N on bottom. Will fix this soon.
Above is illustrration of method to improve power and lower draw in DC pulse motors, by magnets polarizing the cores of coils advantageous to the rotation of the motor - this elimnating magnetic 'clash" of coills and cores with approaching rotor magnet of same polarity.
Power increase of X3 is possible, and draw lowers by half when this technique is used
The core of a coil once the coil has been energized and becomes an electromagentc, will "keep" the polarity of what it became when energized for some time...the core doesnt suddenly switch polarity or suddenly "relax" itself to a "default neutral state" after being energized - it stays the same polarity as it was when energized.....even though the kickback recol spike at turn-OFF will be opposite polarity, this spike will not be enough energy to flip the core of the coil into the same polarity as the spike; so the core stays pretty much the polarity of what it is when it becomes energized into an electomagnet as the mtoor runs
This creates slow-down problems to the rotor on the the APPROACH of the rotor magnets (or rotor coils) to the coil as shown in illustration.
The purpose of the "regauging magent" is that it pulls the CORE of the coil back to an opposite polartity as when it was energized.
And this creates an attractive-PULL situation at the point in rotation where N-N coils and magnets would try to push the rotor backward.... a free power stroke more or less, plus the elimination of rotational loss too, so it greatly incresaes power and speed in the rotor, with less draw to the motor coils too..
In motors with coils vs coils, the re-gaguaging magnet would be positioned right next to,stator coils, not direclty behind them, and "downstream" in rotation,
In coils vs coils motors, the regauging magnet affects the rotor coils and cores only wiht no affect on the stator coils or cores.
