Need help with Axial flux generator

In summary, the conversation discusses the use of axial in wind turbines and how to slow down and stop the turbine in high winds. One method is to "feather" the blades while another is to turn the turbine side on to the wind. The suggestion of using electromagnetic power input to slow the turbine is deemed impractical.

TL;DR Summary
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.
