Study and Analysis of the Switched Reluctance Machine Shaft Position

The switched reluctance machine (SRM) was, during the last decade, target of the attention of researchers. Some studies stand out the application potentialities of the machine, another´s developed the machine design for better performance in terms of efficiency, good torque and speed behavior. Others denote the possibility of good machine functioning without the position sensor and there are still others presenting a way to reduce the noise produced in dynamic regimen. However, there are very few works about the analysis of the machine behavior regarding its shaft position. This work presents some results in this thematic, studying and analyzing its geometry and torque values necessary to develop when a shaft position is intended. Some methodologies are presented in order to be applied to obtain a shaft position. One of them is based on experimental results taking into account the two phases that are necessary to excite simultaneously in order to produce the immobilization of the motor shaft in one determined position.
