Design and Analysis of Rotating Stator in Electrical Machine System

This paper presents a study on effect of rotating stator in electrical machine system. The designed generator is different from the conventional one, in which in conventional system, only rotor is rotating and the stator is fixed. In this study, both rotor and stator are allowed to rotate. The objective of this study is to investigate and analyse the potential improvement to the electrical power generation if the stator part is also allowed to rotate. The direct current (DC) machine is redesigned in such a way that both stator and rotor can be rotated. In this paper, a model of DC generator is observed for the following conditions; when only stator rotates, when only rotor rotates, when both rotor and stator rotate in opposite direction and when both rotor and stator rotate in same. From result, it is observed that the output voltage that is produced when both rotor and stator are rotating is higher than to normal rotor only rotated. This indicates the possibility of generating more electrical power using this configuration.
