i have an amateur in a dc motor bearing 2 magnets symmetrically arranged with North north poles facing 2 coils up and down respectively the down coil repels the down mangnet and moves the whole amateur having the 2 magnets the up one induces forward emf on the up coil and the down magnet induces a back emf on the down coil that powers the dc motor now a device disconnects the upper and down coil immediately the amature rotates away the upper and down magnets coming again to the same point where it was repelled is supposed to induce current on the upper coil now making the upper coil having similar poles with the oncoming upper North pole magnet but since the upper coil circuit is opened there's no current and there's no magnetic field to oppose the incoming magnet, also similar to the down coil and magnet (the driver coil) but due to the aid of the special sensors the driver coil is powered at the right time and the upper coil circuit is closed so that the upper coil forward emf can flow to the down coil emf to counter the back emf since the upper magnet is the same with the lower one and their coils are the same the foward emf is equal to the back emf countering the effect of the back emf in the driver coil now there's no drag in the dc motor the driver no longer draws power from the power source to counter the back emf again to increase the speed to the maximum potential of the magnets, this potentially means elimination of back emf now insisting that the potential energy of the magnets can now be directly involved in the motor's rotational force not just influencing it by creating a back emf to draw more electrical power
