Let us consider the design of the LPEC of a coaxial configuration, containing a fixed inductor 1 and a double armature, enclosing the inductor from opposite sides [8] (Fig.
When a signal is applied to the thyristor VS, the current excites a stationary inductor from the CES C, and due to the emerging magnetic field, eddy currents are induced in each of the parts of the double armature. As a consequence, oppositely directed EDFs of repulsion act on both sides of the double armature on the inductor side, which leads to the total force action of the striker on the object of action.
The goal of the paper is determination of ways to increase the power characteristics of a linear pulse electromechanical converter of induction type with a double armature, designed to destroy information in a flat solid state SSD storage device.
As indicators of LPIEC with a double armature we will use:
* the amplitude of the axial EDF [f.sub.z23m] acting on the fixing clips from the oppositely directed forces on the front and back parts of the double armature [f.sub.z23m] = [f.sub.z2m] - [f.sub.z3m], where [f.sub.z2m], [f.sub.z3m] are the amplitudes of the EDFs acting on the FPA and the BPA, respectively;
* the value of the EDF pulse [F.sub.z23m] = [F.sub.z2m] - [F.sub.z3m] acting on the fixing clips from oppositely directed forces on the front and back parts of the double armature, where [F.sub.z2m], [F.sub.z3m] are the amplitudes of the EDF pulses acting on the FPA and the BPA, respectively; impulse [F.sub.z] - [integral [f.sub.z](t)dt;
Let us consider the LPEC of a coaxial configuration in which both parts of the double armature are identical and are made in the form of a flat disc of technical copper, one of whose sides faces the inductor.
Electrodynamic characteristics and indicators of LPEC with a double armature. Let us consider the influence of geometric parameters on the electromechanical processes of a LPEC of induction type with a double armature.
The maximum value of the EDF acting in opposite directions on the front and back of the double armature is [f.sub.23m]=11.99 kN.

Let us consider the effect of the geometric parameters of the inductor on the indicators of LPEC with a double armature. One such indicator is the thickness of the copper bus b, which affects the number of turns of the inductor [N.sub.1].
Based on the studies carried out, an experimental LPEC model of an induction type with a double armature was developed.
