Need help with Axial flux generator

Click For Summary
Axial flux generators can potentially be used in wind turbines to manage high wind conditions. The discussion highlights the idea of using an external power source to create electromagnetic resistance, aiding in slowing down the turbine. However, the conventional method for managing excessive wind is to "feather" the blades, which is more efficient than actively trying to halt the turbine through power input. Another technique mentioned is orienting the turbine sideways to reduce wind impact and speed. Overall, traditional methods are preferred for safety and efficiency in high wind scenarios.

TL;DR
Can you slow down a axial generator by cutting the flow of the power been generatored and then putting a current back into the generator to slow it down and then hold it at a stop?
I am sure axial are used in wind turbines so i will use it as my example.

Say you are using the wind turbine to generate power but its getting to windy and you want to slow down the turbine to bring it to a stop.

What i want to know is ...

If you can cut off the power that's been generated, to then have power inputted into the generator from another sauce would this then act as a type of electromagnetic and use this to help slow down the turbine to bring it to a stop and hold it in place?

Welcome to PF.

The usual way to deal with high winds is to "feather" the blades of the wind turbine to slow them to a stop. This is much more practical that wasting a bunch of power to actively slow-stop-hold the blades and connected generator.

Another way is to turn the turbine side on to the wind so as to reduce the speed and power.
 
I mentioned in a post some time ago now that, at present, the renewable energy debate here in Australia is mired in economic issues, not technical issues this forum is concerned with. It still is, but a new twist has appeared - the need for synchronous condensers: https://search.abb.com/library/Download.aspx?DocumentID=9AKK107258&LanguageCode=en&DocumentPartId=&Action=Launch All sides seem to agree they are needed, and the discussion is now around their economics. The economics is not in...
