Abstract
The DC generator is widely used in the fields of industry motor control and energy transfer, and the simplex wave winding (SWW) is the main winding pattern of the DC generator. In this paper, a brief introduction to the structure of the SWW is presented first. Then the characteristics
of the current and electromagnetic fields of the SWW are analyzed particularly in a commutation cycle and two typical concepts of the “central slot” (CS) and the “widest magnetic peak area” (WMPA) are proposed respectively. The characteristic frequency which is 63 and
21 times higher than the fundamental frequency (FF) of the voltage between two brushes is obtained and verified from 6 conditions of different speeds and currents. Furthermore, with the help of an induction coil sensor between two main poles, the characteristic frequency 84 times higher than
the FF of the WMPA is also verified in 6 conditions and the results coincides with the theory well.
