when 2 armature coil is contect in one brush so its a make a spark or produced voltage(magnatic filed ) so we give external voltage on brush so its a neutralized the comutation or use a interpole in the core thet mean when we r shift the brush position oposite the reaction so its will be reduced

I dont understand the terms MNA and GNA. Can you please explain me these terms in Layman language?
What are the significances of these axis. How brushes are shifted along with new MNA ?
