1. A vertical wind turbine, comprising:
a plurality of vertical blades each fastened to and motor-driven pivotably around a respective vertical blade axis independently of other vertical blades, and the vertical blades are rotatably supported to travel along a common circular path (K) around a vertical rotor rotation axis (C2); and
a plurality of pitch motors, each pitch motor having a motor shaft,
wherein each vertical blade axis is operatively connected to the motor shaft of a respective pitch motor from the plurality of pitch motors for motor-driven pivoting of the vertical blade that is fastened to the vertical blade axis,
wherein the motor shaft of each pitch motor extends concentrically to a respective blade rotation axis,
wherein each vertical blade axis includes a vane axis section in a region of a vane thereof, and wherein a transition section is positioned between a vane axis section of a vertical blade axis from the plurality of vertical blades and the motor shaft of a pitch motor from the plurality of pitch motors, and
wherein each transition section tapers in a direction extending away from the motor shaft of the pitch motor from the plurality of pitch motors.
