전동차 출입문 신뢰성 향상을 위한 BLDC 전동기 위치제어에 관한 연구|RISS 상세보기

다국어 초록 (Multilingual Abstract)

In this study, we conducted a study aimed at replacing the DC motor, which drives the electric doors of EMU, with a BLDC (Brushless DC) motor. The existing DC motor has contact parts such as brushes and a commutator, which require regular maintenance due to wear caused by rotational contact. This results in decreased motor efficiency, impedes normal door opening and closing operations, and affects the operational lifespan of the drive unit. To overcome these issues and enhance the door system's performance, we propose the adoption of BLDC motors. BLDC motors operate without brushes and a commutator, reducing friction-related heat issues and lowering the probability of malfunctions. They enable stable door operations even with lower power consumption and allow precise control of position and speed using hall sensors. We developed a prototype BLDC motor door hardware based on the existing electric door profile. The motor speed and panel position were controlled through the Hall sensor of the BLDC motor. Additionally, various conditions were experimented based on the existing door speed profile to verify the reliability of the BLDC motor door position control.
