摘要

Purpose

The main purpose behind this study is to evaluate the electromagnetic characteristics and the influence of silicon steel lamination material in vibration attributes of the proposed 8/10 E-core hybrid excitation reluctance motor (HERM) for electromotive applications.

Method

First, the finite element model of the 8/10 HERM is created and analysed using the MagNet software package. The electromagnetic performance of the proposed motor is compared against the conventional configuration. Thereafter, the Ansys mechanical workbench is utilized to evaluate the structural behaviour and vibration characteristics through modal and harmonic analysis. The performance of the proposed motor with different laminating materials like M19, M43, and M890-50d is analysed.

Result

The comparative analysis revealed that the proposed 8/10 HERM exhibits minimum torque ripple, higher efficiency, and high torque per weight while utilizing less volume than the conventional configuration. The influence of lamination materials in structural, modal, and harmonic analyses revealed that in electromagnetic aspects, the proposed motor with M890-50d material provides higher torque, less ripple, but its efficiency is less than motor with M19 material. Through the structural analysis revealed that 8/10 HERM with M890-50d material experienced highest deflection of 0.032 m at 10 Nm. In addition, motor with M890-50d materials its having less natural frequency than other two materials. In this perspective, the motor with material M19 is chosen which prefers higher natural frequency of 375 Hz and exhibits the least deflection of 0.16 mm at the time of natural frequency. It is also observed that the structural response of the 8/10 HERM with M19 silicon steel material exhibits the least deflection under different load conditions compared with other laminating materials. Through electromagnetic analysis, motor with M19 material yields moderate torque, higher efficiency and ripple.

Conclusion

The current study evaluates the performance of 8/10 HERM with different laminating materials. The study’s comparative analysis shows that the proposed motor with M19 silicon steel lamination material is well-suited for electromotive applications due to its first-rate structural, vibration, and electromagnetic attributes.
