Abstract
The paper offers an approach to Computer Aided Design of low‐voltage linear actuators, from the aspect of geometry, as the level preceding their optimal design. Magnetic circuit geometry in addition with the shading pole and exciting coil are taken as the objects of CAD. Complete complex computer program FEM‐3D is developed for this purpose. Finite Element Method — FEM in three dimensional domain is used in order to compute the field distribution, as well as for the evaluation of working characteristics.

Abstract
Experience and exploring the linear AC and DC actuators confirm the necessity of the computation of forces distribution as the step preceding their optimal design. This paper expresses an approach to computations of different forces of low‐voltage linear actuators acting on both mechanical and/or electrical parts. The computations are based on magnetic coenergy concept associated with virtual work method and simulated by step displacement of the armature from the total open through total closed position. The magnetic coenergy is numerically computed through the flux‐linkage approach, where the magnetic field distribution is obtained by applying the finite element method in 3D‐domain.
