The Development of 152kVA High-speed Large SmCo Permanent-magnet Sub-exciter

The Application of SmCo permanent-magnet material to high-speed large SmCo permanent-magnet sub-exciter can improve property of permanent-magnet electric machine in many ways. The construction design, choice of permanent- magnet material, optimized design, fablication technology and test of 152 kVA SmCo permanent-magnet sub-exciter are inquired into Test results of this sub-exciter show, that the employed construction can sufficiently make use of the fentures of SmCo permanent-magnet All indexes of the sub-exciter, the machining and assembling technologies could meet the requirements of excita- tion system for 600MW turbogenerator and laid a good foundation for further developing of large permant-magnet sub-exciter.
