BLDC 전동기의 설계 및 특성 해석에 관한 연구

Abstract

In general, because the brushless DC motor has a high power out and could be small size, light weight with magnets and development of a electronic technology use of that have been important. Especially, because a core type brushless DC motor with a silicon steel has a simple shape and its manufacture process is very easy mass production is possible. This paper describes the characteristics analysis of the brushless DC motor by using the commercial finite element method. The basic design is done by the commercial software(Ansoft RM Exprt) and the characteristic analysis of the brushless DC motor is done by Maxwell software. We can get design data and characteristics curve of the brushless DC motor from the design software. The design software can change the design data to the analysis model for finite element analysis. The cogging torque and back e.m.f characteristics are obtained from the finite element analysis.
