Abstract
The article presents the spectral analysis method of the magnetic fields to be able to evaluate transversal and longitudinal effects, based on Fourier integral transformations. It has been determined that the expressions of the relative spectral characteristics of the braking force and power coincide. In accordance with the derived expressions, the software program Mathcad 2001 Professional was used for the calculation of the dependencies of the transversal effect on the relative spatial frequency and under different Reynolds’s numbers. The results of the calculation indicate that when increasing the width of the secondary element, the influence of the transversal effect on the braking characteristics tend to be reduced.

Summary
The controlled linear induction drives are used in the modern mechatronic systems for generation of direct motion. They allow the simplifying of the system itself because the mechanical chains of the movement replacement are not required. The braking of the linear induction motor plays a very significant role for positioning. The electric braking of LIM comprises a separate specific scientific and technical problem. The scientists from various countries investigated separate modes of LIM braking [2]–[4]. The electrical modes of braking are analysed the most extensively, presuming that the velocity of the motor during
