The Horizontal Axis and Vertical Axis are the types of Wind turbines or windmills. In the Horizontal Axis Wind Turbine, the rotor couples the electrical generator, and the generator is placed on top of the turbine tower. On the other hand, in Vertical Axis Wind Turbine, the rotating shaft is vertically aligned. Wind Turbines refer to the machines that are used to convert wind energy into electricity. It uses a generator for this purpose.

Horizontal Axis and Vertical Axis Wind Turbines

In Horizontal Axis Wind Turbine, three blades having lengths from 20m to 80m are horizontally aligned. The blades are usually white in color so that they can be viewed by aircraft easily. It has a gearbox in between the turbine shaft and the generator shaft.

The gearbox is responsible for providing mechanical coupling between these two shafts. It also steps up the slow rotating speed of the turbine blades to the high rotating speed of the generator. Vertical Axis Wind turbines are shorter in height than Horizontal Axis Wind turbines. Hence they can be installed even on the rooftop.

  • These turbines are more suitable for areas where the direction of wind significantly varies.
  • Although Vertical Axis Wind Turbine has so many advantages over Horizontal Axis Wind Turbine
  • They cannot be used for bulk power generation because the output power is less.


Horizontal axis and Vertical axis of turbine are the types of

Wind turbines have different types, such as Horizontal Axis and Vertical Axis. A Wind Turbine is a machine that uses the kinetic energy of wind to generate rotational mechanical energy in its shaft. After that, the rotational motion helps in generating electricity. Both horizontal and vertical axis wind turbines have their strengths, but the latter has more advantages in general.
