Every coil owns one segement in each commutator if the segments equal the armature poles. Some commutators have segements doubled vs. motor poles. Then there are 2 segments per coil.
Standard windings reverse current flow / polarity after passing the brush. This causes apparently unevitable losses along reduced torque in high rpm area.
Asymmetric windings get pulsed when contacted to brushes and then are leaved alone performing the magic we are after.
Conforming P. Lindeman the electric energy being truely converted into mech movement perfoms with factor 3 (300%). In figures: 36W in / 6W converted in 18W mech power / 30W losses. I the view as a blackbox we measure COP 0.5 and feel it is a natural law - but it is not.
Please study the thread for details.
