摘要
本电机是在谐波励磁的三相发电机的基础上设计研制的。本文从理论上阐述了:谐波励磁能使发电机具有两种不同的外特性;谐波绕组不同(对称或不对称)布置可满足两种外特性要求;谐波绕组匝数和弧焊绕组外特性的计算方法。经5kVA两用发电机实验证明,论述正确并可行。
This alternator was developed from harmonic excitative 3-phase alternator.Discusses. 1) principle that the harmonic excitation makes the alternator provide two unsimilar types of load characteristic; 2) principle for the symmetric arrangement of harmonic winding; 3 ) calculation for the number of harmonic widing turs and the load characteristic of arc-welding. By the test at a 5 kVA alternator, the demostrations have proved to be correct and practical.
