[QUOTE="CWatters, post: 5443855, member: 423469"] Before working on the brake I suggest you connect a variable load to your turbine. Pick a constant wind speed and while changing the load plot a graph of the power output. For example with no load (open circuit) the output current will be zero so the output power will also be zero. With a high load (eg short circuit) the output voltage would be zero so the output power would also be zero. Somewhere in between the power output will be a maximum. It sounds like you are planning to use the generator voltage to control the brake. I'm not sure that is a very good idea. For example when the brake is ON the turbine will slow down causing the voltage to drop which will release the brake. You may find the brake switches itself on and off a lot causing it to wear out? I believe the brake needs to be latching, either electrically or mechanically? [/QUOTE]
