Abstract:
kground and Objectives: The rotor of synchronous reluctance machines (SynRM) is conventionally designed and implemented in two types of axially-laminated anisotropic (ALA) and transversely-laminated anisotropic (TLA). Torque ripple and power factor have always been the design challenges of this machine; however, with proper design, their values can be as close as possible to the desired value. Each of these two structures has some advantages over the other, in terms of electromagnetic performance and ease of construction. For the first time, in this paper, a hybrid anisotropic rotor is presented with both radial and axial laminations, Based on the theory of anisotropic rotor structure for the fundamental harmonic and isotropic rotor structure for other harmonics, so that the designed motor meets the advantages of both structures as much as possible.Methods: To this end, the proposed design is implemented and investigated a Magnetic Equivalent Circuit(MEC) for the first slot harmonic on a machine with stator of ۲۴-slots. To evaluate the proposed design, its electromagnetic performance is simulated using Finite Element Method.Results: The theory-based conceptual design method is applied to a rotor with new structure and simulation results including average torque, power factor and torque ripple of the machine are presented.Conclusion: Based on the obtained simulation results and comparing performance of the proposed design with other structures, it is shown that there will be a significant improvement in electromagnetic features including torque ripple, average torque and power factor and the proposed design has lower torque ripple than ALA rotor and higher average torque and power factor than TLA rotor.
