DETAILED DESCRIPTION - The device for transforming outer intermittent forces energy into electric power especially usable for sea wave energy conversion, comprises a section having inductor unit for changing magnetic flux within a predetermined space, armature unit for inducing electric current to the changing magnetic flux, control unit to switch on and off the coils/to regulate the amounts of induced electric currents in the coils, resilient unit for damping excessive the outer forces in a forward direction to facilitate the linear reciprocating movement in the backward direction/vice-versa, cooling unit, and impelling unit engaged in a reciprocating motion actuated by the outer forces. The inductor unit is movably disposed. The armature unit is immovably placed within the predetermined space. The number of the magnets is fully placed within the armature step length equal to a natural odd number. The inductor unit comprises permanent magnets and an inductor core to conduct the magnetic flux. The magnets are mounted on side of the inductor core. The neighboring magnets are positioned to couple with the inductor core in the opposite magnetic polarity. The armature unit comprises an armature core to conduct the magnetic flux, outstanding teeth equably distant from each other mounted on the armature core, and electro-conductive coils wound on the armature core so that the coils are positioned between the teeth. The inductor is engaged in a movement relatively to the armature unit along a direction. The armature core and the inductor core forms assembly pair type from a linear assembly, an annular assembly and a pendulum assembly. The armature core and the inductor core are shaped as linear bodies to elongate the direction in the linear assembly. The armature core and the inductor core are shaped as an annular body in the annular assembly. The armature core and the inductor core are shaped as annular segment bodies in the pendulum assembly. The inductor unit has a movement in the form of revolving about an axle. The magnets are equidistantly disposed on the inductor core, except the ending magnets having a distance greater than the nonending magnets. The teeth are made of different heights. The height of the teeth of the portion is increased toward the direction of the revolving. A portion of coils is made of wire turns with different cross-section areas. The areas are increased in the coils to disposed toward the direction of the revolving. The outer forces and parameters of the revolving movement have higher efficiency of the energy conversion. The section has armature core and the inductor core forming a pair of the linear assembly type. The inductor unit is capable to carry out the movement in the form of linear reciprocating movement. The resilient unit comprises permanent magnets, spring member, hydraulic shock absorbing device and pneumatic shock absorbing device. The permanent magnets (110, 116) are positioned in the opposite polarity to each other and a first magnet of the one pair coupled with the armature unit means and the other magnet of the one pair coupled with the inductor unit, so that the pair forms a predetermined repulsive magnetic field. The spring member with predetermined characteristics has a first end of the spring member coupled with the armature unit, and the other end of the spring member coupled with the inductor unit. The hydraulic shock- and the pneumatic shock absorbing device are placed between the inductor unit and the armature unit. The cooling unit has cooling pockets arranged in the vicinities of the coils, a first cylindrical compartment, and piston of a sombrero-like shape having cylindrical sidewalls, a bottom, an opening, and a flat ring. The edge of the opening is continuously coupled with an inner edge of the flat ring and an outer edge of the flat ring snug-fitting within the cylindrical sidewalls of the first compartment. The piston is made of materials with high heat conductivity. The piston divides the first compartment into a primary and a secondary cooling portion. The primary and the secondary portion are fillable with a primary and secondary cooling liquid.
