Abstract	A method for calculating the electromagnetic processes in a cylindrical linear electronic motor (CLEM) taking its field three-directional distribution into account is considered. The radial-axial topology of the magnetic CLEM field is considered to be three-dimensional. Numerical calculation of the three-dimensional CLEM field depends on the excessively large computational volume, which can be significantly decreased by reducing the problem to a two-dimensional one. It can be numerically solved in the course of several minutes by using a computer, while the three-dimensional problem requires several hours. The magnetic field of the CLEM and rotation motor were analyzed from the YZ plane of the air gap. Comparison showed that the magnetic field of both motors along the axis of motion is distributed and is homogeneous if motion is across the axis. Analysis of the fields allowed one to conclude that it is possible to transform the three-dimensional geometrical model into a two-dimensional one. This is done around the air-gap plane. The model transformation causes a change in the air-gap topology. The circular air gap of the CLEM is transformed into the line of the rotary motor along the Y axis of the models. For the Z axis, the CLEM rotates in a circular air-gap rotary motor. Geometrical model transformation equations are derived. The CLEM calculation method allows the finite-element technique to be used with small time losses and sufficient accuracy.
