On the question of taking into account the main dimensions when selecting type of electromagnet according to value of constructive factor

Abstract

Using the finite-element modeling of the magnetic field with the help of Finite Element Method Magnetics (FEMM) software, the influence of the ratios the electromagnet’s main dimensions on the values of constructive and efficiency factors has been stated. The possibility of taking into account the constructive parameters and the limits of their rational use more explicitly has been shown based on the example of calculating a suction DC electromagnet with a conical frustum that operates the air gap.
