- the N is a total number of the blades, where the N is a natural number greater than 2,
- the Am is a distribution size of distances between the blades (equal angles), where 0°<Am<360°/N,
- the i is a sequence of the blades, where the i=1, 2, 3, 4, . . . , and N, and
- the P1 and the P2 are factors having an effect on a period, where 0≦P1≦N, and 0≦P2≦N, the P1 and the P2 being real numbers.
