Optimized Design of Switched Reluctance Motor Based on a New Rotor Structure

In this paper, the theoretical analysis and structural optimization of switched reluctance motor are studied to improve the vibration and noise of this type of motor. Starting with the structure of the motor, a switched reluctance motor with a new rotor structure is analyzed and designed. By changing the magnetic field distribution inside the motor, the new rotor structure reduces the vibration and deformation of the stator core and the shell, thereby it can improve the vibration and noise of the motor in operation. By using the finite element analysis method of electromagnetic field, the simulation analysis shows that the radial magnetic force and torque ripple between the stator and rotor of the new type of rotor -structure switched reluctance motor can be reduced to a certain extent, and at the same time the higher efficiency can he obtained, then enhancing the performance of the motor comprehensively. Finally, the simulation results are compared and analyzed to obtain the optimal parameters of the prototype rotor structure.
