Review comment:
       @acassis Just adding some extra information, having the number of poles 
which is tipically given the foc controller is able to convert the mechanical 
angle into the electrical one.
   
   The only extra requirement that may have to be considered is a initial park 
and go alignment to keep the IQ + ID pair aligned to a initial known value and 
consider this offset to the account when converting mechanical into electrical 
angle.
