A new chapter 11 has been added to report KD 571 in which the VIRYA-1.36 rotor and PM-generator are described. Chapter 11 gives an alternative of circular magnets in stead of square magnets. The advantages of circular magnets are: 1) The total magnet costs are lower. 2) The fluctuation of the AC voltage is more sinusoidal. 3) Mounting is easier.
