Electric motors are electromechanical machines commonly used in industry and automotive products. Interior Permanent Magnet Synchronous Motor (IPMSM) is a synchronous electric motor with a permanent magnet that is often used on electric vehicle engines. However, one of the characteristics of an electric motor with permanent magnet is the existence of torque ripples. The presence of torque ripples in electric motors can cause vibrations in the machine which affect efficiency, structural durability and operating speed. Therefore, it is necessary to make improvements or changes to the motor design to overcome this problem. This study was conducted to analyze the effect of a modification of the electric motor parameter on the torque value in the existing design. Modifications are applied to the existing design with an initial condition of torque ripples of 42.58%. This study modified the air gap, magnet angles, magnet thickness, and opening slot width. Modifications are carried out through a finite element method-based software simulation with the Taguchi method to reduce experimental configurations of design factors from 625 to 25 experiments. Through this research on parameter modification, the results of the analysis show that each modification of the design factor has an influence on the value of torque ripples. From the process of Analysis of Mean (ANOM), it can be seen that wider air gap and slot opening, the smaller torque ripples. Then, the greater magnet rib and thicker magnet cause the greater torque ripples.

In addition to research related to static eccentricity and dynamic eccentricity examining fault and diagnostic methods in various types of motors, there are also studies conducted for motors with non-uniform air gaps similar to the condition. In these studies, improvements and changes in motor performance for such types of motors can be observed. In this study, the effects of the rotor structures determined in the study and the air gap shape, which is effective by changing the eccentricity ratio, on the motor performance of the interior permanent magnet synchronous motor designed for electric vehicle applications are examined. Besides the elliptical rotor structure, which is widely researched in dynamic eccentricity studies, these eccentric motor structures also include novel rectangular and polygonal eccentric rotor structures. Motor models with non-uniform air gap structures are designed in two dimensions and subjected to simulation and analysis studies using the finite element method. At the end of the study, along with the parameters identified for motor performance, the harmonic components of the stator current, radial air gap flux density and the output torque obtained through Fast Fourier Transform analysis have been provided.

Synchronous Reluctance Motors (SynRMs) have attracted a lot of attention in recent years due to their simple construction, high efficiency and the fact that they do not require rare earth magnets. SynRMs produce torque by directing the magnetic flux through barriers in the rotor, making them a low-cost alternative. The performance of the motor can vary significantly depending on the design of the stator windings and rotor barriers. Different combinations of stator winding types and the number of rotor barriers directly affect the critical performance parameters of the motor such as torque, efficiency, torque ripple, output power, saliency ratio and copper consumption. In this study, SynRMs using six different stator winding types and two different rotor barrier structures (3 and 4 barriers) are analyzed. Output power, efficiency, torque, torque ripple, saliency ratio, d-q axis inductances depending on current phase angle, total losses and copper consumption are investigated. The effect of full pitch and shortened pitch configurations in winding structures on the performance is discussed comparatively. The effect of 3 and 4 barrier rotors on these parameters is also evaluated. These analyses aim to reveal the ways in which winding and rotor configurations in motor design can be used to optimize performance. SynRMs can provide energy efficiency and cost benefits in a variety of industrial applications, therefore selecting the proper configuration is of great importance from both an economic and performance perspective.
