Abstract
A novel compound permanent magnet (PM) generator with adjustable air-gap flux is investigated. The proposed structure and control principle are described in detail and design equations are completely derived. By using three-dimensional (3-D) finite-element analysis, the electromagnetic distribution and the performance evaluation are carried out. A 7.5 kW prototype generator is manufactured and tested. The calculated data are compared with the experimental data. It is obvious that the proposed structure generator has good regulation characteristic by means of variation of dc field current.
