A novel four layer switch reluctance generator

High acoustic noise and vibration are two of the main drawbacks, which have limited the widespread application of switched reluctance machine (SRM). Therefore, many studies have been performed to reduce the acoustic noise and vibration of these machines. This study introduces a novel, practical and analytical structure for the switched reluctance generator (SRG). The proposed generator consists of four magnetically independent stator and rotor layer sets. Each layer works exactly in a complementary way with the neighboring layers to convert mechanical energy into electrical energy perfectly. In the proposed generator special switching technique is implemented in order to reduce the amount of torque-ripple and vibration which can also reduce the amount of acoustic noise. Extensive computer simulations are performed to investigate the theory and feasibility of the proposed SRG structure of this study.
