“…For the conventional multi-layer SRM, different layers have similar structures as observed for a 4-layer 8/6 SRM in Figure 1. To determine the optimum value of alpha, below equation is suggested here: (17) where N phase and N layer are the number of phases and layers in the multi-layer SRM, respectively. With this explanation, it is clear that torque ripple of the conventional multi-layer SRM and the one-layer SRM is the same.…”

Summary In comparison to one‐layer switched reluctance motor (SRM), a multi‐layer SRM is able to produce much larger output power and it can be considered as a good candidate for high‐power electric machine. For a multi‐layer SRM, different layers have the same performances and they are completely independent from electromagnetic point of view. Therefore, analysis of one layer can be only carried out to determine the electromagnetic characteristics of the multi‐layer SRM. In the present paper, a fast and simple magnetic equivalent circuit (MEC) model is introduced for one‐layer SRM and it is then used for performance prediction of the multi‐layer SRM. Due to high torque ripple of the SRM, a simple solution is suggested for different types of the multi‐layer SRM by which torque ripple of this motor can be reduced significantly. To evaluate the done modeling and the suggested torque ripple method, simulation results are presented for a typical multi‐layer 8/6 SRM.

“…In, 14 a 3-layer 4/4 SRM is presented in which torque is produced only by one layer in each instant of time. A different configuration is proposed in 17 for the 2-layer 6/4 switched reluctance machine. A 5-layer 4/4 SRM is introduced in 16 in which a single rotor is considered for all layers and there is a displacement by 18°between two adjacent stators.…”

“…Higher number of rotor segments than the stator slots are considered to reduce the overall volume of the motor, which results in increased torque density, reduced winding overhang length and compact motor. In addition, a novel type of two-layer 6/4 three-phase SRM was proposed to reduce torque ripple in [18][19]. This SRM has a higher starting torque capability and lower torque ripple and acoustic noise when compared to a classical SRM.…”

This paper presents comparative studies between a novel modular switched reluctance machine (SRM) with modular E-core stators and segmental rotors and a conventional SRM. Owing to the particular construction, there are hybrid magnetic paths with both radial and axial magnetic paths in the modular E-core stators SRM. To evaluate the motor performance, a 3D modeling finite-element analysis (FEA) is presented to simulate its flux distribution. Comparisons of static magnetic characteristic and dynamic performance between the modular SRM and the conventional 6/4 SRM are made to emphasize and evaluate the advantages of this novel SRM. Finally, a prototype modular SRM is built and tested in the laboratory. The measured static flux linkage characteristic and dynamic operation of the MSRM are presented to verify the theoretical and simulation results.

“…In contrast with PMSM, the structure of the switched reluctance generator (SRG) is rather simple, with no windings and permanent magnets on the rotor. Further, the SRG can generate DC power directly with strong fault tolerance [20]. Therefore, the SRG is suitable to work in the harsh sea environment.…”

The dynamic model for a bidirectional driven float-type wave power generation system design is presented in this paper. The gravity, buoyancy and drag force acting on the wave energy converter (WEC) are all analyzed. The analytical expression of the torque applied on the rotor is given based on a linear model of the switched reluctance generator (SRG). The SRG usually rotates with low velocity in the WEC system. In this situation, current chopping control (CCC) is adopted with fixed turn-on angle and turn-off angle control mode to have a quick response for SRG. Further, in order to make the float keep in phase with the wave so as to improve the power generation efficiency, the reference current is dynamically adjusted according to the wave motion at all working stages. Then maximum power point tracking (MPPT) of system is achieved. A simulation model is developed in MATLAB for the bidirectional driven float-type wave power generation system with real wave statistical characteristics taken into account. Simulation results show that the WEC can output desired torque periodically with high efficiency and good adaptability. Therefore, the feasibility of applying a SRG in a WEC is also verified.
