ABSTRACT

The structure of separated shielding coil(SSC) is analyze and it goes, the magnetic field of the center cause is calculated and the result is confirmed through the simple experiment. In case of considering the materials for shielding of the separated shielding coil as the iron sheet it compares with the case which is not shielded and it measures actually and the shielding factor is found and we define to the numerical formula. It is the object that it is seen like the brush less direct current (BLDC) pulse there is no sensor using SSC and without the brush that acceleration control of the ferromagnetic ball is possible.
