This chapter presents a modal analysis of the electric motor automotive component. Using the finite element approach, the frequency responses for the electric motor’s rotor component were calculated. The results of the modal analysis of the electric motor’s overall deformation frequency are compared between the stator and rotor parts. The electric motor components are designed using CATIA V5, which also made it simpler to assemble complex pieces. Using ANSA, which turns the domain into a mesh and immediately shows the failure part, the electric motor is refuted. Modal vibrations are calculated using a numerical method. To prevent resonance, rigid body and natural frequencies are computed and shown in various modes. The system is investigated using the ANSYS finite element (FE) code.

摘要

This chapter presents a modal analysis of the electric motor automotive component. Using the finite element approach, the frequency responses for the electric motor’s rotor component were calculated. The results of the modal analysis of the electric motor’s overall deformation frequency are compared between the stator and rotor parts. The electric motor components are designed using CATIA V5, which also made it simpler to assemble complex pieces. Using ANSA, which turns the domain into a mesh and immediately shows the failure part, the electric motor is refuted. Modal vibrations are calculated using a numerical method. To prevent resonance, rigid body and natural frequencies are computed and shown in various modes. The system is investigated using the ANSYS finite element (FE) code.
