Analysis of BLDC Electric Motor Shaft Treatment Model Using Numerical Method

Abstract

This research studies the shaft strength of a BLDC electric motor. A Shaft is one of the components in a rotary engine and functions to transmit power. The design calculation is needed to determine the effect of the strength of the material being treated. The strength analysis of the shaft used FEM (Finite Element Method). The shaft is modeled on the manufacturing design and tested by numerical simulation with Ansys Mechanical 14.5-BRIN commercial license software. The static simulation used a structural statics module with static and dynamic load input. The research method comparing the results of FEM simulations with two different types of materials is determined. Based on the simulation parameters, the selected material types are JIS S45C tempered and AISI 1045 cold-drawn. The simulation results represent the maximum stress (von Mises) and total deformation. The deformation value of S45C tempered material is slightly higher than that of AISI 1045 cold drawn. However, both materials have the same maximum von Mises stress.

The Prediction of Stress and Safety Factor of Shock Absorber Based on Cyclic Loading Using Finite Element Method

“…However, the use of cyclic loading for analysis offers increased precision and suitability as it reveals transient conditions during the process. In this current study, FEM was considered due to its capacity to address challenges related to discrete element, particularly complex structural models 12,16) . Additionally, the application of FEM proves highly effective for structural analysis, resulting in time and cost savings in laboratory experiments 17,18) .…”
