The sources of energy lost in an artillery shot have been analyzed. It is proposed to use the anti- recoil devices energy of movement for generation, accumulation and storage in the form of electrical energy for the energy independence of the unit in course of a combat task.

For this purpose, a linear pulse generator with a smooth anchor of magnetoelectric excitation, the structure of the active part of which was investigated, was applied.

The principles of structure discretization of the electromechanical converter to the linear impulse generator were applied, which made it possible to optimally use the active materials.

The assertion is used that in the case of an unsaturated magnetic conductor, the magnetomotive force of a permanent magnet is applied mainly to the nonmagnetic gap, so the basic height criterion is the equality of the height of the magnet with the magnitude consisting of a winding layer thickness and the technological gap between the magnet and the surface, and the thickness of the core is equal to the total thickness of the stator's backs and slider cores.

The optimal values of the pole division rate for the specified values of the inner and outer diameters of the designed generator have been set.

The basic relations for determining the optimum values of the width and height of the magnet, the thickness of the stator core and the slider backs have been provided, taking into account the scattering coefficients and bringing the area of the magnetic core to its average diameter, which takes into account the reduction of the magnetic field due to the diameter decrease compared to the inner magnet diameter.
