| Abstract: | A classical magnetic circuit method is adopted to establish the relationship between the voltage characteristics and the structural parameters of the REPM Synchronous Generator With which,the influence of structural parameters on the voltage characteristics of the REPM synchronous generator is analyzed,and a practical and useful program is made to produce a new type synchronous generator with reduced inherent voltage regulation in comparison with old ones The comparison between the calculations and the tests of the two type synchronous generators shows that the method with a program,written in an advanced program language MATLAB,can meet the precision reguirement of engineering The comparison also shows that the method is simple and effective |
