As the first step, the uniformity factor α is initialized at 0.5,
which is the minimal value to maintain the benefit of constant
flux. The plate thickness Hp , and radii RO1, RI 1 , and RO2 can
be calculated by solving (1)–(4) simultaneously. After Hp is
determined, the radii of the remaining winding windows can
be obtained recursively from (2) and (3); note that the total
number of winding windowsNw is limited by the manufacturing
constraints such as the width of the winding and the distance
between the winding and the center of the core. The number of
turns nj is approximated from (5) and (6). Since nj is a rounded
