The problem with these windings are reduced torque, increased BEMF and no possibility of extracting inductive kickback. Its good for speed control and reducing arcing at the brushes. The advantages of a simple winding are the reverse of this. What was considered the big disadvantage was the arcing but these days we can extract that energy and use it elsewhere.
