Design of a 5 MW, 9000 V switched reluctance motor

This paper presents an 8/6 switched reluctance motor with tapering poles, which is capable of carrying larger current and producing larger torque while the flux density remains unchanged. And this feature makes it possible of using high temperature superconducting windings to improve the torque potential of electrical machines. Finite element analysis with commercial software is utilized to support this result.

“…-The mechanical losses due to friction in the bearings and windage between stator and rotor can be approximated by [20]: where R is the phase resistance and rms I is the effective phase current. -For iron losses estimation there are many models however for fast and still accurate estimation the model of reference [21] has been adopted. The model is based on experimental work and background knowledge of how core losses vary in conventional machines:…”

This paper presents a new method for multiobjective optimisation of a switched reluctance motor. Four objective functions regarding motor efficiency, power factor, torque ripples and outer volume are considered. The proposed method combines fuzzy logic, genetic algorithm and simplex technique as a general global optimisation technique. The new technique is searching for the best compromise solution, which maximises the designer total degree of satisfaction. In order to predict the motor performance accurately , a hybrid FEA-analytical simulation model has been adopted. The model combines some of the FEA accuracy with the simplicity of analytical model. A full time stepping FEA analysis for the optimised motor has been done to verify the final design of the motor.

In this study, radial forces that create noise, which is a fundamental problem in Switched Reluctance Motor (SRM), are investigated. Since radial force causes stator vibrations and noise caused by magnetic field, a new switched reluctance motor model with increased stator and rotor poles has been designed in order to reduce the radial force acting on the rotor poles. In addition, a structure with high torque and low leakage flux compared to conventional winding structure has been proposed for Switched Reluctance Motors (SRM). The windings of the designed SRM are placed in layers, insulated from each other. Rotor poles are formed to move on both sides of each phase winding. Thus, the flux that will occur in the phase windings axially completes its circuit from the stator poles and the rotor poles. This designed ARM model has been examined by Finite Element Method (FEM. The proposed motor geometry has been analyzed with ANSYS Maxwell-3D, which performs FEM-based solution), and parametric analysis with ANSYS-RMxprt.
