Abstract
An overview of methods for calculating and designing linear electric generators with permanent magnets is given. The techniques are grouped according to the type of calculation approach used. A detailed analysis of the proposed methods and assumptions is carried out, conclusions are drawn about the possibility of their use in the design of electric generators with permanent magnets with solid magnetic circuit elements. The main assumptions are related to the representation of the parameters of the equivalent circuits of magnetic systems. It was found that the main part of the methods does not take into account the influence of magnetic hysteresis and eddy currents in solid elements of the magnetic circuit. It is shown that many approaches aimed at designing electric machines with permanent magnets can be adapted to linear electric generators.
