LINEAR ELECTRIC GENERATOR Russian patent published in 2021 - IPC H02K35/02 H02K11/30 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, namely to linear electric generators. Under action of gravity of cylindrical barrel (5) and magnetic core of cylindrical shape with axial magnetisation (4) and force of spring (8) pressing movable contact (7) is in contact with lower contact platform (10). Key (13) is closed and current flows through spring (8). There is an attractive force between adjacent turns of spring (8), as result spring (8) begins to contract and magnetic core of cylindrical shape with axial magnetisation (4) will start to move upwards. As a result, sign-reversing magnetic field of permanent magnets of magnetic core of cylindrical shape with axial magnetisation (4) induces electromotive force of sinusoidal shape in turns of cylindrical coil with axial winding (3). Further, as a result of separation of movable contact (7) from lower contact site (10), electric current and force of compression of spring (8) disappear and magnetic core of cylindrical shape with axial magnetisation (4) begins to move down under action of gravity, inducing electromotive force in turns of cylindrical coil with axial winding (3).

EFFECT: expansion of functional range.
