The paper presents the results of a study to develop a method of modeling the magnetic flux on the shaft and in the end panel of the electric machine. Development of a method due to the necessity of designing diagnostic protective systems are based on using information of a magnetic field asymmetry in the end zone of the electrical machine. The method is based on the idea of separating the element from the magnetic flux into two equal parts on a path along the boundary surfaces and the anti-clockwise, followed by summation of the elementary streams from the bypass element along the ferromagnetic channel. The method is simple, reliable, and allows you to get the value of the magnetic flux in the shaft and face shield at the point of measurement with an accuracy of about 20%, which satisfies its requirements.
