Did you compare your calculated number of turns per slot (62) to the number removed from the old winding? Can you explain the connection of the 4 windings per phase? These seem to be in series but it is not addressed in the text.
In step 40 - I believe your indication of the magnetic poles is reversed - the North should be to the top for current flow as shown (into the page on the right).Can you elaborate on the connections of the windings? You show two sets of two windings per phase. Are these series, parallel, or parallel-series connected? I see some light colored lines on the winding diagram - are those connection points?
Excellent tutorial. Not to be critical, but in the table "Loaded motor test" it appears that "1996" should be "1966", and maybe the voltages are swapped (higher voltage should have higher phase current and higher "power in"?).
