I am trying to use a DC motor as a generator for a wind turbine but then there are two possibilities for the DC motor which are brushed and brushless. Which one is more efficient to use?
I know that if I use a brushless motor then I need to use a 3 phase rectifier which includes 6 diodes. Will the voltage drop in these 6 diodes affect efficiency? But if I use the brushed motor then I don't need to use the rectifier. Can this be the advantage over the brushless motor?
