Electromagnetic Fields on 3-Phase Induction Motor Using Finite Element Analysis

Abstract

Electromagnetic fields of a 3-phase induction motor, i.e., electric and magnetic fields and current density, are highly influenced by its geometry, conductor material (conductivity, magnetic permeability, electric permittivity, and nonlinearity), and boundary conditions applied (interface between conductors and dielectrics). Through Finite Element Analysis (FEA), the behavior of electromagnetic fields can be predicted. Thus, favoring the electromagnetic interference mitigation techniques of the 3-phase induction motor. Therefore, this paper presents numerical modeling with FEA, based on COMSOL, as an early pre-compliance tool to investigate the current density distribution and electric and magnetic fields. The validation of the modeling approach will be presented and discussed considering a 3-phase induction motor. Furthermore, CISPR 25 will be considered to evaluate the interactions between electric and magnetic fields, current density distribution, and skin effect on an increasing frequency.

Versatile LabVIEW-FPGA-based Testbench for Electromagnetic Interference Evaluation in VSDs

“…The standard IEC 61000-1-2 describes electromagnetic compatibility (EMC) as the proper functioning of equipment or systems in their intended environment without interfering with other devices used in their intended environment. It implies in that the prediction, design and test of devices are of great importance and are useful to evaluate EMC in development process of a product [2]. Thus, having a cyber-physical that supports such a design process and prototyping is essential to assess EMI from devices.…”
