Abstract

In this paper, a blind spot of motor car, and the put case that is driven the miniature model motor system, when make practical application of the permanent magnet synchronous motors(PMSM) braking and having had the ability that can all absorb regenerative power by means of electric brake which is occurred. a tow system of a miniature model motor traction system is established by 1C1M methods to control individually permanent magnet synchronous motors (PMSM) of each motor. vector control method is applied in order to improve ride quality of motor car and the efficient use of energy. it was obtained excellent experiment results from the simulations as a function of momentum load and miniature model. Also, this study is investigated the regenerative braking power securities of permanent magnet synchronous motors, speed detection to stop electric brake at extremely very low speed and motor control method of algorithm.

본 연구는 전동차를 운전 시, 영구 자석형 동기전동기(PMSM)가 제동할 때 발생한 회생전력은 모두 활용하며, 전기제동에 대하여도 발생한 회생전력을 모두 흡수할 수 있는 능력을 가진 축소모형 전동기 시스템으로 운전함을 가정한다. 축소모형 전동기의 견인시스템은 각 전동기는 영구 자석형 동기전동기(PMSM)를 개별로 제어하는 1C1M방식으로 구축 하였다. 전동차의 승차감 향상 및 에너지의 효율적 이용 등을 위한 방법으로써 벡터제어 방법을 적용하여 관성부하에 대한 시뮬레이션과 축소모형으로 실험을 하여 좋은 결과를 얻었다. 또한, 영구 자석형 동기전동기(PMSM)의 제동력 확보에 의한 회생제동 제어 확보와 전기제동으로 정지하는 극 저속에서의 속도검출과 전동기를 제어하는 방법의 알고리즘에 대하여 연구 하였다.
