A vertical wind power generator for converting wind power into electricity, comprising: a support base; inductor coils fixed in position over the support base in a circular array; an annulus ring track fixed to the support base and configured to provide a circular track around which the circular array of inductor coils is located; rollers placed in the circular track of the annulus ring track so as to roll in the circular track and to move around the annulus ring track; an annulus ring rotor placed on the annulus ring track and engaged to the rollers in the circular track of the annulus ring track so that the annulus ring rotor can rotate relative to the annulus ring track by operation of rolling motion of the rollers in the circular track without having a rotary shaft in the center of the annulus ring rotor for rotating the annulus ring rotor, the annulus ring rotor structured to include separate magnets evenly spaced from one another on an outer peripheral of the annulus ring rotor to move through the circular array of inductor coils as the annulus ring rotor rotates with respect to the annulus ring track so that the relative motion between the magnets and the inductor coils causes generation of electric currents in the inductor coils; and a cylindrical wind rotor assembly located above and fixed to the annulus ring rotor to form a unified assembly to rotate with the annulus ring rotor relative to the annulus ring track, the cylindrical wind rotor assembly structured to include wind-deflecting blades that are spaced from one another and arranged in a circle around the cylindrical wind rotor assembly to form a hollow central cylindrical interior space for containing a wind vortex formed from deflecting of the received wind by the wind-deflecting blades, to convert received wind from any direction into a rotation of the unified assembly relative to the annulus ring track, thus causing conversion of the wind energy into the electric currents in the inductor coils. a support base; inductor coils fixed in position over the support base in a circular array; an annulus ring track fixed to the support base and configured to provide a circular track around which the circular array of inductor coils is located; rollers placed in the circular track of the annulus ring track so as to roll in the circular track and to move around the annulus ring track; an annulus ring rotor placed on the annulus ring track and engaged to the rollers in the circular track of the annulus ring track so that the annulus ring rotor can rotate relative to the annulus ring track by operation of rolling motion of the rollers in the circular track without having a rotary shaft in the center of the annulus ring rotor for rotating the annulus ring rotor, the annulus ring rotor structured to include separate magnets evenly spaced from one another on an outer peripheral of the annulus ring rotor to move through the circular array of inductor coils as the annulus ring rotor rotates with respect to the annulus ring track so that the relative motion between the magnets and the inductor coils causes generation of electric currents in the inductor coils; and a cylindrical wind rotor assembly located above and fixed to the annulus ring rotor to form a unified assembly to rotate with the annulus ring rotor relative to the annulus ring track, the cylindrical wind rotor assembly structured to include wind-deflecting blades that are spaced from one another and arranged in a circle around the cylindrical wind rotor assembly to form a hollow central cylindrical interior space for containing a wind vortex formed from deflecting of the received wind by the wind-deflecting blades, to convert received wind from any direction into a rotation of the unified assembly relative to the annulus ring track, thus causing conversion of the wind energy into the electric currents in the inductor coils.
