谈直流发电机的基本工作原理、电枢反应及换向

直流发电机与直流电动机具有相同的结构,只是直流发电机是由原动机拖动旋转而发电。可见,它是把机械能变为电能的设备。文章以直流发电机为讨论对象,论述了直流发电机基本工作原理、结构、电路、磁路、运行原理、电枢反应及换向问题,指出了直流电机的最大弱点就是电流换向问题,并分析了影响换向的因素。

On DC Generator Principle,Armature Reaction and Commutation

DC generator as well as DC motor has the same structure but the former generates power by driving and rotating prime mover.Thus,it is a sort of equipment that can change mechanical energy into power.Through the discussion of DC generator,the paper elaborates the working principle,the structure,the circuit,the magnetic circuit,the operation principle, the armature reaction and the commutation of DC generator principle and points out that the main deficiency of it is the current commutation,meanwhile,analyzes...
